Replacing the steering rack on a VAZ 2110, VAZ 2111, VAZ 2112

Welcome! The steering rack is responsible for turning the wheels of the car; inside the rack there are mechanisms that make it not so difficult to turn the wheels with the help of the steering wheel, but it is comparable to if you turned the wheels by hand; in addition to the steering rack, the steering rack is also responsible for the easy rotation of the wheels power steering, the power steering can be Electric or Hydraulic, on cars of the tenth family only power steering was practiced, on cars of Ukrainian assembly (Bogdan) an electric power steering was also installed, we should immediately note that removing the steering rack with a hydraulic power steering will be more difficult than without it, you will have to tinker a little, so immediately tune in to this and take into account the fact that a steering rack with power steering costs much more, in addition, when buying a new rack, try to take a new one assembled so that all the tips are there, and so on, if you do this and don’t save a little If you spend a little money, the installation will go much faster and you won’t even have to bother with the rack.
Note! To remove this part, stock up on: Blocks of wood, you will need to put the front part of the car on them and remove both wheels from the front, if you have a pair of jacks, then you can leave the car hanging on them, but it can simply fall off the jacks, all the keys that You also have a large flat-head screwdriver that will come in handy, as well as pliers and a mounting spatula with a hammer!

Summary:

Where is the steering rack located? The rack is located on a shield that separates the engine compartment and the interior of the car, the rack is secured using two metal clamps that secure it on the sides, through a small hole in this shield, the rack goes into the passenger compartment where it connects to the steering shaft, you can understand everything schematically in more detail, You can look at the photo below, in which everything is indicated, but only that very shield (Partition) is not there, and the rail is indicated under the number 18.

When should you change your steering rack? A sign that the rack needs to be replaced is a characteristic knock that will still transfer to the steering wheel, as well as play in the steering wheel, if all these symptoms do not disappear by adjusting the steering rack (How to adjust the rack, read “in this article”), then In this case, the steering rack needs to be replaced.

Symptoms of a problem

Without proper care, such as lubricating bearings and checking play, the steering rack can quickly fail. Signs of malfunction that indicate that the mechanism should already be changed:

• A noticeable knock when driving over bumps, which is transmitted to the steering wheel. If a knocking noise is heard when turning the steering wheel, it is unsafe to drive such a car; it is necessary to urgently diagnose the mechanism.
• Strong play in the steering wheel indicates loose fasteners or wear of the rack-and-pinion joint.
• The effort when turning the wheels has increased.
• You can hear noise from the hydraulic booster (if equipped).
• The cause of the knocking noise may be an insufficiently lubricated bearing or wear of the gear-rack pair. If, when rocking the steering shaft, there is noticeable play at the junction with the rack, repair is necessary. If not, just check and tighten the joints between the bushing and the steering shaft gear.

A powerful vice is used to fasten the rail

How to replace the steering rack on a VAZ 2110-VAZ 2112?

Note! Before buying a rack, you should know something, firstly, before you buy a new rack, look at the markings on the old one and buy according to it, racks are generally interchangeable, but to avoid problems, buy everything according to the index and by the way, if If you have power steering installed, then take the new rack from the power steering!

1. Before you start work, unscrew the wheels so that they are pointing towards the front, then hang the front part and remove both front wheels from the car, but before that, carefully secure your car so that it does not fall to the ground, but To do this, you will need to put it on the handbrake, put wheel chocks under the rear wheels just in case, and most importantly, the area on which you are going to do the work must be flat and must be asphalt, in case the car does fall, place the wheels under it in advance ( So that he falls on them).

2. Let's go to the salon, while there, you will have to use two keys (one bolt must be kept from turning) to unscrew the nut of the bolt that compresses the clamp clamp, with the help of which the propeller shaft is held on the splines of the steering rack, after the nut is unscrewed, and the bolt is removed (see small photo), insert a powerful screwdriver into the slot (where the bolt was, indicated by a blue arrow) and with its help, unclench the clamp so that the driveshaft can easily come off the steering rack splines.

3. Now, on both sides, pull out the steering tips from the holes into which they go, we will briefly explain how to pull out the tip using the example of the right side, in general, take pliers and use them to pull out the key (This is a kind of metal wire), as soon as it is pulled out, unscrew the nut and using a puller, press the tip out of the hole and that’s it, if you need pictures and you have no idea what a steering tip is, then in this case read the article: “Replacing steering tips”, it says everything in detail.

4. When both steering tips are removed from the holes, proceed to unscrewing the bolts that secure the rods themselves (the steering rods are located on these rods), they are directly screwed to the steering rack in the central part (To remove the bolts, pry up the locking plate with a screwdriver, it is not allows the bolts to unscrew spontaneously) by turning out one bolt at a time, completely remove the rods from the car (you need to pull them out through the wheel arches) and as you already noticed in the small photo, when removing the rod, the person still holds the connecting plate, do not lose this plate when turning out the last bolt , always hold this plate with your other hand.

Note! When the rods are removed, check their silent blocks (These are rubber bands, you will see them immediately, because the rod itself is metal and the rubber part is just silent blocks), their rubber should not be damaged, cracked or have signs of age, otherwise In this case, replace the silent blocks with new ones (see “Replacing silent blocks in rods”) and by the way, worn silent blocks can cause play in the steering, so keep this in mind!

5. And finally, unscrew two nuts on each side that secure the steering rack to the shield, remove the metal clamps and through the arch, remove the rack completely from the car, you can see all this in more detail by looking at the photos below:

Note! This is how absolutely all the racks that were installed on the VAZ 2110 family are removed, while the racks with the power steering are removed in a slightly different way, before starting work you will need to pump out the liquid from the tank with the power steering with a syringe, disconnect the hose from the tank and then put it in any bottle, not when starting the car, turn the steering wheel until all the fluid has drained from the hose, for more detailed instructions on how to remove the rack from the power steering, read the article: “Replacing the steering rack on a Lada Priora” and by the way, when reinstalling it, make sure that the steering rack is installed to the splines according to the marks (For more details about this, read the article: “Replacing the rack on Kalina 1”, point 1) If you need to change the EUR on a Priora? Read - Do-it-yourself electric power steering repair on a Lada Priora.

Additional video clip: Look at the detailed instructions for replacing the rack, it is shown on the example of a VAZ 2109 car, everything is done exactly the same on it, and we will even tell you more, the first generation of the VAZ 2110 was produced with a steering rack from the ninth family, so the differences are There is no removal at all, either on the first car or on the second.

Dismantling, diagnostics and installation of the steering rack

Regardless of whether the rack is being repaired or replaced, it must be properly removed and reinstalled.

Replacing the steering wheel on a “classic” is not at all difficult if you have the proper desire. Information on dismantling can be obtained from this material: https://vazweb.ru/desyatka/upravlenie/kak-pomenyat-rul-na-klassicheskih-modelyah-vaz-2101-2107.html

List of DIY tools

For dismantling and repair you will need the following tools:

• flat screwdrivers of different sizes;
• pry bar or mounting blade;
• small hammer;
• pliers;
• torque wrench;
• a set of socket and ring wrenches ranging in size from 10 to 27;
• open-end wrenches for 10, 13, 15;
• special key for adjusting the steering rack. Such a key can be purchased at a car dealership or made independently.

The need to replace the steering rack: diagnostics

To restore the performance of the steering rack, it is not always necessary to replace it; often the problem can be solved by carrying out maintenance with the replacement of tips, covers and bushings. Beginners should not service the steering wheel on their own. The design of this mechanism has many springs and pressing washers, and not everyone can disassemble the mechanism, sort through the parts and correctly replace them with new ones. Unprofessional installation of these parts will lead to incorrect functioning of the mechanism. The same applies if you need to loosen the mechanism or tighten it. It is also necessary to remember that repair work may well be more expensive than replacement, so the choice is sometimes obvious.

Steering rack repair kits of different compositions are produced for VAZ 2110 vehicles. They also differ in the year of manufacture and the presence of an amplifier.

Experienced car owners restore the slats themselves, but this is not always possible

The steering wheels of VAZ 2113-2115 cars do not have an outstanding design, so many car enthusiasts prefer to replace them. To carry out an independent replacement procedure, it is recommended that you read this article: https://vazweb.ru/desyatka/upravlenie/kak-snyat-i-zamenit-rulevoe-koleso-na-vaz-2114-i-2115-svoimi-rukami.html

It is necessary to change the part in the following cases:

• a crack in the rack body or the threads for fastening the tips are broken;
• very strong knocking in the rack, increased play in the steering mechanism;
• corrosion of the internal parts of the steering rack caused by rupture of the rubber boot;
• the rack was deformed after the accident.

In the above cases, restoring the removed part does not make sense. Restoration by professional craftsmen will cost a lot of money. Therefore, it would be more expedient to change the entire rail, which will require less time and financial costs. It will be much easier to purchase a new one in the store and install it assembled in place of the old one, ensuring excellent operation of the steering mechanism for several years to come.

In order to do a wheel alignment in a VAZ 2110 car, it is not at all necessary to contact a car service center. Details of the procedure: https://vazweb.ru/desyatka/hodovaya/razval-shozhdenie-vaz-2110.html

Installing a new

After diagnosing and repairing the rack, we install it in place:

1. We set the rack to the middle position. To do this, unscrew the shaft in any direction until it stops and return it 2.5 turns. The shaft flat should be on the right and located vertically.
2. Carefully insert the mechanism through the arch and secure it in the reverse order of dismantling. Tighten the bolts with a torque wrench.

If the steering system malfunctions, you should not immediately call a service station or buy the entire unit. If you have basic plumbing skills, you can repair and adjust the steering rack in your own garage. At the same time, you will be sure that you did not spend extra money and the work was done to a high standard.

Signs of steering rack defects, dozens and pre-repair preparation

A sign indicating problems in the steering mechanism, and most likely in the rack, is a knocking sound in the steering mechanism. It manifests itself when driving on a bumpy road surface, where the road is replete with potholes, holes and bumps from uneven soil or expanding asphalt. This creates a feeling in the car user that this knock is heard directly into the steering column. If such sounds occur in the steering system, it is necessary to diagnose it.

What is the risk of a faulty steering system?

Car steering mechanism

Timely identification of a steering rack malfunction and its repair is the key to safety.

If there is play in the steering mechanism, and there are also constant noises and knocks when driving on uneven roads, then this is a sign that the mechanism requires repair.

Causes of malfunction

The design of the rail itself is relatively simple. During operation, the parts of the mechanism may wear out, so gaps appear between them, which will cause backlash.

Steering design

Anthers also play an important role in the rack, protecting the mechanism from dirt and dust, as well as moisture.

If the rubber boots are damaged or there are leaky places in them, this may cause some problems that may be associated with corrosion or contamination of the assembly elements .

Steering rack diagnostics

If uncharacteristic behavior of the car on the road while driving was noticed, then it is necessary to determine what caused it. There are not many ways to diagnose reiki. They are all simple. Among them are the following:

1. a knocking sound is heard in the area where the rack and steering shaft meet when force is applied , then the problem is a lack of bearing lubrication.
2. If, by grasping the joint of the rod in the engine compartment, play is detected , this will be evidence of wear on the bushing or insufficient tightening of the connections.

Removing the steering rack bushing

Replacing steering shaft bearings VAZ 2110 1996

1. Disconnect the wire from the “–” terminal of the battery.

2. Remove the steering wheel (see subsection 5.3.1).

3. Loosen the bolt securing the base of the steering column switches and slide the base towards you. 4. Disconnect the wire from the oil pressure sensor. 5. Disconnect the two connectors with the horn wires from the contacts on the base and remove the base of the steering column switches.

6. Insert the key into the ignition switch and turn it to position I to unlock the steering shaft.

7. Disconnect the ignition switch wire block from the wiring harness. If the ignition switch wires are connected to the wiring harness with a clamp, cut or loosen the clamp.

8. The steering column is secured with bolts with break-away heads (the same as the ignition switch). If new bolts with breakaway heads are not available, you can replace them with regular M6 bolts 20 mm long.

9. Unscrew two nuts and two bolts with break-away heads, remove spring and special washers. If the bolt heads are stripped, the bolts must be drilled out or removed using a screwdriver and hammer.

10. Remove the steering column from the studs, slide it towards you and lower it down. Then remove the bolt securing the propeller shaft to the steering shaft.

11. Remove the bolt and remove the column assembly, while removing the thrust bushing from the shaft. 12. Press the steering shaft along with the bearing out of the pipe. It is recommended to press the shaft towards the steering wheel mounting.

13. Remove the front (steering wheel side) bearing from the shaft.

14. Replace the steering shaft if the splines or threads are worn or damaged.

15. Using light hammer blows and a drift, press the rear bearing out of the steering bracket pipe.

16. Before installing the bearings, check that they rotate easily and without jamming. The plastic bearing bushings must not be damaged.

17. Press the rear bearing all the way into the pipe collar using a suitable mandrel, applying force only to the outer race of the bearing. The bearing is mounted on a plastic bushing, which has a wide flange on one side. When installing the bearing, it is the wide flange of the bushing that must be directed outward.

18. Slide the front bearing onto the shaft with the wide flange of the bearing bushing facing the end of the shaft.

19. Insert the shaft into the pipe. In this case, the rear end of the shaft should enter the rear bearing.

20. Press the front bearing all the way into the pipe collar using a suitable mandrel, applying force only to the outer race of the bearing.

21. Install the steering column in the reverse order of removal. Install the thrust bushing on the shaft with the side with the larger diameter.

22. Install special washers for the bracket fastening bolts with their protruding part a in the opposite direction from the bolt head. 23. When installing the base of the steering column switches, before tightening the bolt securing it, adjust the position of the base on the steering column. To do this, install the lower casing and move the base so that the screw holes in the casing and the base match. After this, carefully remove the casing and tighten the base bolt. Install the steering wheel in the reverse order of removal.

What is needed to replace the steering rack of a VAZ 2110

To replace the old rack with a new VAZ 2110 we will need: WD-40 fluid, a vice, a puller for removing the tips or a hammer, an open-end wrench “13”, “22”, “19”, a socket wrench with a head “13” , “17”, “22”, chisel and screwdriver, pry bar, jack, new steering rack.

You should pay attention to the fact that the VAZ 2110 power steering steering rack with the article number (21100340001030) costs much more. When buying a new rack, it is more profitable to take the rack assembled so that there are rod ends, etc., and it is better to choose a new part when you have the old one on hand

The price of a standard rack for a VAZ 2110 with article number (21100340001200) will be about 2,500 rubles, and an improved version with power steering costs 15,000 rubles.

The cost of spare parts is indicated for spring 2022 in Moscow and the region.

Tools and materials for work:

• Socket head for fifteen, nineteen, twenty-four;
• Power driver;
• Two jacks;
• Ratchet driver;
• Wheel bolt wrench;
• Wheel chocks;
• Socket wrench for ten, thirteen;
• Pliers;
• Wire cutters;
• Extension;
• Hammer;
• Five hexagon;
• Steering wheel pin remover;
• Key for adjusting the steering rack;
• Wire brush;
• Rubber hammer;
• Mounting lever;
• Crosshead screwdriver;
• FIOL lubricant;
• Slotted screwdriver;
• Penetrating lubricant.

We carry out repairs

Remember that this unit is a rather “delicate” and fragile mechanism.

under the octagonal nut of the stop there is a spring that needs to be removed;

then remove the retaining ring, which is located under the specified spring;

lightly tap the wooden spacer to tap the rack stop out of the crankcase (note that there is a rubber sealing ring in the groove of the stop);

Next you need to remove the front shield seal;

• under the seal there is a boot, which is also removed (you can use a screwdriver that has a wide and thin blade);
• behind the boot there is a locking ring, which is also removed;

Using a 24mm octagonal head, unscrew the gear bearing mounting nut and remove the nut from the shaft;

we press out the shaft from the gear together with the bearing using a 14mm wrench, which we rest on the mounting blade; the shaft can be clamped in cleats;

• we remove the protrusions of the support sleeve from the holes in the crankcase using a screwdriver;
• •Next we remove the bushing.

Before installing the new support bushing, install new damping rings on it. This must be done in such a way that their thin part is opposite the cut of the bushing. Next, make sure that the purchased repair kit fits your steering rack (VAZ 2108 or 2110), if it does not fit, then you will have to go and change it, we also recommend getting special keys for repair the steering rack, if it has not been done before.

install a new bushing, before doing this, do not forget to lubricate the area under the bushing;

now you need to cut the rubber rings along the contour of the bushing and remove the cut parts with a special knife;

• the next step is to remove the retaining ring from the gear shaft;
• then you need to press out the ball bearing with a special puller to replace it with a new one;

to press out the needle bearing, we use another puller; if there is none, you will have to cut the bearing with a chisel;

• wash the crankcase cavity;
• install the rail;

but before that we check it for the integrity of the teeth;

we install a new needle bearing (we use cold welding for this; we perform reassembly; it is recommended to install a new protective cover and secure it with clamps (the price of the cover is low); we adjust the rack clearance (it is important to tighten the nut all the way, bending the thread, and then loosen it , turning the key in the opposite direction 30 degrees; do not forget about the lubricant that needs to be filled with the steering rack

That's the whole process, which involves repairing the steering rack of a VAZ 2110 car.

This instruction will help you save significant money and allow beginners to become familiar with the main parts and fastening options for this mechanism.

And it will help experienced car enthusiasts avoid many common mistakes.

Disassembling the steering rack

1. Remove the support and protective cap from both sides of the mechanism.
2. Release the protective covers.
3. Remove the stop nut using a special wrench.

Remove the stop nut

Removing the drive gear with bearing

Remove the support sleeve

Next, you need to replace all the elements that are included in the steering rack repair kit, check the product for play and conduct a visual inspection.

After disassembling the rack, special attention should be paid to the worm gear mechanism and the support sleeve. Also, if the anthers are damaged, then corrosion of some parts of the mechanism may occur.

Everything here needs to be cleaned and rinsed, and also generously lubricated.

It is imperative to change the retaining ring and the rack stop . These parts are subject to the most wear and tear.

Cotton steering wheel and how to deal with it

The design of front-wheel drive VAZ cars corresponds both to its price niche and partly to its purpose. An average car for economical travel over average distances at average speed. Know-how of the 80s of the Soviet automobile industry, the MacPherson suspension coupled with rack and pinion looked like something perfect in the early 80s. Although, in fact, the long-travel steering rack 2108 and the classic MacPherson of the 1948 model are not the most progressive solution even for a cheap car.

Compared to classic VAZ models, rear-wheel drive, with a classic steering mechanism and double-wishbone front suspension, the 2110 has more sluggish and imprecise handling. In a word, a wadded steering wheel. It won’t take long to figure out why this happened. Elementary geometry - MacPherson does not hold the car well in turns and during acceleration and braking, and the steering had a long stroke and an unsuccessful upper rack location. Hence the looseness of the steering wheel. It is technically inherent and cannot be cured by any settings or adjustments.

Video tutorial on repairing a VAZ steering rack

However, since the 2000s, a slightly improved design of the power steering rack has been used. There wasn’t enough for everyone at once, because first of all, cars with hydraulic booster were exported. Later, when Europe was full of Zhiguli cars, cars with power steering began to appear more often. But the hydraulic booster did not save the situation. And that's why.

Step-by-step replacement of the steering column

Having decided to replace the steering column on a VAZ-2106 yourself, you need to stock up on free time and patience, and experts recommend performing this step in stages:

1. The steering shaft, which is clamped in the column, should be carefully removed.
2. Using a size 30 wrench and a long wrench, you should try to rip off the connecting nut that secures the steering column. It is not always possible to remove the fasteners the first time, but since this stage is mandatory, you have to return to it several times.
3. The three fasteners that connect the column to the car body are unscrewed. It is most convenient to use a so-called ratchet for this process, since the bolts are not so easy to get to with a regular wrench.
4. After unscrewing all the fasteners, you need to free the column from the tie rod splines, which continue to hold the assembly. To do this, you should pry the structure with a pry bar and try to knock it down with sharp jerks.
5. After dismantling the unit, it is necessary to check the condition of the boot and oil seal; if even minor damage is detected during a visual inspection, these components must be replaced. By installing a new boot, the life of the bearing and shaft will be extended, and the new oil seal will not allow automotive lubricant to leak out of the steering column.

If all components are installed correctly, the car owner will replace the failed elements with high-quality and reliable ones, and the steering column will have a long service life.

To simplify the assembly process, experts recommend putting all the removed elements from the car in strict sequence, so that when assembling the structure, you don’t confuse anything and repeat the whole process again.

As you can easily see, the process of replacing the steering column of a VAZ-2106 is not that complicated, so every car owner can do it if he has the strength and patience and, of course, does all the work step by step. But if difficulties still arise when replacing a car element, it’s time to use the hint, which at a convenient time can be found in the video instructions on the Internet resource. The educational video lesson is conducted by qualified specialists who understand the intricacies of car repair and present their visitors with extremely effective and most necessary advice on the topic of interest to them.

Checking the oil level in the steering column on a VAZ 2101-VAZ 2107

Welcome! Steering column - thanks to it, both front wheels of a rear-wheel drive car of the “Classic” family are turned. In order for the steering wheel to rotate well and with little effort, the steering column is constantly lubricated with oil located inside it. But like any other oil, the oil inside the steering column disappears over time, and therefore its level must be constantly monitored and topped up whenever possible. You can find out how to check the oil level below.

Note! To check the oil level in the steering column, you will need to take: “8” wrenches, and also, just in case, take with you a funnel, clean oil and a brush or just a rag!

Where is the steering column located? Most likely, you have already seen where the steering column is installed, and more than once, because it is located in almost the most visible place, namely in the engine compartment of the car, on the left side (Indicated by a red arrow), and just above the steering column is the main brake cylinder on the photo indicated by the blue arrow.

How can you tell if there is very little oil in the steering column? Everything is very simple! Usually, when the oil in the columns disappears or there is very little of it, the car’s steering wheel begins to turn heavily, and when you turn the steering wheel, various kinds of sounds and knocks can be heard in the engine compartment of the car, namely the sounds will be made by the steering column itself.

How to check the oil level in the steering column, is it the steering mechanism?

1) First, clean the entire top surface of the steering gear cover from dirt.

2) Next, unscrew the oil filler bolt indicated by the arrow.

3) And after unscrewing the bolt, check through the hole how much oil is left in the mechanism.

Note! If there is not enough oil, install a funnel and add it! (For information about what kind of oil should be poured into the steering mechanism, see our website “here in this article”)

4) And then screw the oil filler bolt into place.

Important! Avoid getting dirt into the steering gear housing!

Dismantling the rack on a VAZ-2112

First, you will need to remove the battery, the platform under it and the air duct in the engine compartment. Next, you will need to unscrew the clamps that secure the rail to the body. The difficulty of this work is that if you unscrew it carelessly, you can damage the studs , which are quite difficult to replace.

Removing the tie rod ends from the steering rack

After this, you should unscrew the bolts that hold the rod ends. Next, the flange bolt securing the rack is unscrewed. After this, you need to fold the rail away from the body. This will require a pry bar or crowbar. You can pull out the mechanism through the hole in the mudguard. A jack will be needed here.

Replacement

As already mentioned, the work of removing and installing the steering rack on the “ten” is quite simple. Before starting repairs, it is important to prepare the car for work. Disconnect the battery, of course, you will not be working with an electrician, but it will not be superfluous to be careful. Jack up the car and place jack stands under the rear wheels. Place a special stand under the car itself. Pre-treat all threaded connections with penetrating lubricant.

Replacement is carried out in the following order:

• Remove the front wheels;
• It is advisable to remove the left locker; it will interfere with the removal of the rack. But this is optional;
• Unscrew the screw securing the coupling. You can get to it from the salon. To do this, you will need a socket wrench “13”;
• Disconnect the steering knuckles from the steering knuckles. After that, be sure to use a caliper to measure the distance from the ball joint to the rod. This will allow you to approximately set the wheel alignment angle, and get to the service center without any problems for more precise adjustment;
• The rail is attached to the body with 2 screws. You need to unscrew them. This is done from the engine compartment. For greater convenience, use a head with an extension. While unscrewing, be sure to hold the part. After unscrewing the screws, move the rail, make sure that it is not secured anywhere else;
• Remove the rack through the left arch.

Inspect the removed part. If the problem is damaged boots, then it makes sense to simply replace them. To do this, purchase a repair kit for the steering rack. But keep in mind that most likely dirt has already gotten there. Therefore, after such repairs, the part may break quite quickly, and it will no longer be repairable.

Assembly is carried out in reverse order. But there are some nuances here. All threaded connections must be pulled with a specific torque. To do this, be sure to use a torque wrench. All connections must be coated with Litol 24 or graphite grease before assembly. After 100 kilometers, check the tightness of the nuts and screws.

Diagnosis of steering problems dozens

Every car has weaknesses. For VAZ 2110, this is the tie rod end. This part is an integral part of the car's steering system. The tie rods on the tenth generation VAZ end with tie rod ends. Rods are rarely changed, but tie rod ends must be replaced every 40 thousand kilometers of the car.

But this is an average and approximate figure. The service life of the steering tip depends on the driving style of the car owner and the conditions in which the car is operated.

How to determine the condition of the slats?

Hold the steering shaft near where it meets the rack and try to pull it up and down. If you hear a knock, the rack housing requires repair. The issue may be a lack of lubrication in the needle bearing.

To check the play of the bushing and the contact of the rack with the steering gear, you need to grab the joint of the steering rods from under the hood and try to move the shaft. If the problem is that the joints are not tightened enough, this is not very bad, but if the joints are coming from the rail, you will have to choose one of the following options:

• purchasing a new rack for a VAZ 2110;
• restoration of worn slats by craftsmen;
• do-it-yourself rack repair.

Selection of repair kit

Before starting repair and restoration work, you should decide on the choice of repair kit.

Minimum set. This set includes the necessary list of fastening and sealing elements: washers, bearings, nuts and fluoroplastic bushings.

The basic set has bearings and shafts in addition to the minimum set, but its cost can be twice as high as the first option.

Please note that the steering rack can be either old or new. The old racks are designed for the VAZ 2108, while the new ones are designed for the “tenth” model. The new version is also more convenient to repair. If there is a need to repair the steering rack, which involves replacing the bushing, then there is no need to disassemble the entire mechanism. Remove the corrugation, unscrew the central nut and disassemble the rack into two component parts. One part will contain the mechanism, and the other part will be the one where the bushing is located.

Preparatory activities

The first thing you need to do is buy a steering rack repair kit. Without it, starting work is completely useless. The set may have different configurations.

• Minimum (washers, fasteners, bushings, nuts, bearings).
• Medium (in addition to all of the above, shafts are added). The cost of such a kit is twice as much.
• Maximum (everything is included here, including the rack).

Please note that there are different slats - old and new. The former are intended mostly for the VAZ 2108, and the latter for the VAZ 2110. It is better, of course, to give preference to the second option, because in this case the bushing is much easier to change (there is no need to disassemble the entire rack).

Steering innovations

It seems like the issue has been resolved. Now it was possible to increase the force on the steering wheel, make the number of revolutions from lock to lock minimal, everything was smoothed out by the amplifier, but another problem arose. The car is operated in too different modes and the exact dosage of the steering angle at speeds of 140 and 55 km/h have completely different values. Not to mention the fact that there was almost no effort on the steering wheel, which made the steering even more insane. Then we had to change the design of the steering rack again. This time the objects of attention were the rack/pinion pair. Installing a new pair helped. The new steering rack was called “short” because the number of steering revolutions was reduced from 3.8 to 2.9. As a result, the waviness has almost disappeared and the steering wheel has become sharper.

This was achieved by using an uneven distribution of tooth pitch. In the central position of the steering wheel and at very small angles of rotation, the force on the steering wheel remains noticeable. This is very useful at high speeds. When actively maneuvering, in a parking lot, in heavy traffic and in cramped conditions, the greater the turning angle, the less force on the steering wheel. So the ten began to be controlled more clearly, without losing its lightness. How this affected the maintenance of the rack and its resource is a separate conversation.

How does the steering mechanism work?

Steering

injury-proof, with a height-adjustable (tilt-angle) steering column, and a rack-and-pinion steering mechanism.

Steering gear

assembled with steering rods, it is attached in the engine compartment to the front panel of the body on two brackets using brackets 2 (Fig. 1). The mechanism is secured with nuts on welded bolts through rubber pads (supports) 3.

A drive gear is installed in the steering gear housing 5, which meshes with the rack.

The steering shaft consists of an upper 14 and an intermediate 10 shaft, connected to each other by a cardan joint. The intermediate shaft is connected to the drive gear by a flange through an elastic coupling. The upper shaft is installed in the bracket pipe 21 on two ball bearings with elastic bushings on the inner ring.

Fig1. Steering parts: 1 – inner tie rod ends; 2 – steering gear mounting bracket; 3 – steering gear support; 4 – spacer ring; 5 – steering mechanism; 6 – sealing gasket; 7 – thrust plate of the seal; 8 – seal; 9 – lower flange of the elastic coupling; 10 – intermediate steering shaft; 11 – coupling bolt; 12 – spacer sleeve; 13 – facing casing (upper part); 14 – upper steering shaft; 15 – steering wheel; 16 – signal switch cover; 17 – adjusting sleeve; 18 – steering column position adjustment lever; 19 – retaining ring; 20 – facing casing (lower part); 21 – steering shaft mounting bracket; 22 – steering shaft bearing; 23 – adjusting rod; 24 – outer tie rod end; 25 – spring ring; 26 – protective cap; 27 – sealing ring

At each vehicle maintenance check the condition of the protective cover, the protective caps of the 26 linkage joints and the tightness of their fit. They must be replaced if there are cracks, ruptures or other defects that impair their tightness.

Make sure that the steering wheel spoke is horizontal when the vehicle's wheels are straight. Otherwise, determine the cause of the problem and correct it.

Turn the steering wheel from lock to lock and check visually and audibly:

- reliability of fastening of the steering mechanism and steering wheel;

- is there any play in the rubber-metal joints, in the steering rod joints, as well as in the rivet and spline joints of the elastic coupling of the steering shaft;

-reliability of tightening and locking the bolts securing the rods to the rack and the nuts of the ball joint pins;

- are there any jams or obstacles that prevent the steering wheel from turning?

If knocking or binding is detected, disconnect the tie rods from the swing arms of the telescopic suspension struts and recheck. After confirming that the knocking and sticking noise is coming from the steering, remove the steering gear from the vehicle for repair.

The maximum permissible gap between the stop and the nut is 0.2 mm. If necessary, replace worn parts and adjust the gap between the stop and the nut.

Basic faults

Like any other mechanical structure, the steering rack, due to certain circumstances, may show signs of malfunction. These include:

• crunch (knock) when turning the steering wheel;
• “tight” steering wheel;
• increased play in the steering wheel or steering shaft drive gear;
• vibration of the steering shaft when driving;
• uneven tire wear caused by improper alignment of the front wheels.

The listed symptoms indicate that it is time to repair or replace the steering rack. However, do not rush into replacement. The rail itself is made of durable steel, and it is not so easy to damage it. Most often, auxiliary structural elements become unusable:

• support sleeve;
• drive gear bearings (ball and needle);
• seals;
• anthers, etc.

There can be any number of reasons for the failure of these parts, from spent resources to mechanical damage due to off-road driving. If you are sure that the rack itself will not have to be changed, you can get by with minor repairs to the steering structure, which consists of replacing the listed “consumables”.

If you decide to repair the steering rack at a service station, expect that you will have to pay about 300 rubles for the simplest repair kit. A complete set, including bearings, will cost about 500-700 rubles. The entire filling, including the rail, will cost 1,500 rubles.

It is advisable to know the markings of the rack before purchasing a repair kit, since they may differ depending on the configuration and year of manufacture of the “tens”.

The cost of repair work, depending on the service station, will be 1000-1500 rubles. If you don’t want to overpay for the work, you can repair the rack yourself.

Work order

1. Remove the steering rack assembly.
2. Cut the clamps securing the boot (cover) of the steering mechanism.

3. Unscrew the thrust nut of the rack (octagonal special wrench 17), remove it from the body.

4. Remove the rubber plug from it. Use a screwdriver to remove the retaining ring and spring.
5. Lightly tap the steering housing on a wooden block to knock out the rack stop (piston) and remove it along with the seal.

6. Remove the boot and drive gear seal (slotted screwdriver).
7. Remove the lock washer (slotted screwdriver).

8. Unscrew the nut securing the drive gear bearing (octagonal special wrench 24 with a central hole with a diameter of at least 18.5 mm).
9. Remove the rack drive gear with bearing from the housing.

10. Remove the rack from the housing.
11. Pull the support sleeve out of the body by prying it with a slotted screwdriver.
12. Remove the retaining ring from the drive gear shaft. Check the bearing for play. If there is one, use a bearing puller to remove the ball bearing from the shaft. Install a new one in its place in the same way.
13. Remove the needle bearing from the housing by drilling two holes with a thin drill (2 mm) on the back of the housing and knocking it out using a thin rod. Seal the resulting holes with “cold welding” or “fast steel”. As a last resort, the bearing can be broken using a narrow chisel (not recommended!).

14. Liberally lubricate the seat, install a new needle bearing into it, and press it into place by lightly tapping its housing.
15. Install a new support sleeve from the repair kit, cut its rubber O-rings, and remove unnecessary fragments.
16. Fill the inner surface of the rack body with special lubricant (Fiol-1 or equivalent).
17. Insert the rail into the housing.
18. Reinstall the drive gear and bearing. Secure it with a nut and install a retaining ring. Place a new boot on the gear shaft.
19. Replace the new stop with the new seal. Secure it with a locking ring. Place a spring in its hole. Tighten the thrust nut.
20. Adjust the rack by first tightening the stop nut all the way and then loosening it 30 degrees. Plug the nut hole with a rubber plug.
21. Place the boot on the rack body and secure it with clamps.
22. Install the rebuilt structure on the car.
