As you can see, repairing the steering rack with your own hands is quite possible for a person familiar with repairs in general terms. By the way, mechanical and hydraulic steering racks, which are much more common than their modern counterpart - an electronic steering rack, are subject to self-repair. The latter requires special configuration, which is best left to professionals.

The steering rack is the power unit of the steering system, which makes it easier for the driver of the vehicle to rotate the steering wheel.

• rice. 2 – with hydraulic booster (with power steering);
• rice. 3 – with an electric amplifier (with electric power steering).

Steering rack device without power steering

The service life of the steering rack is affected by:

• degree of wear of other elements of the steering system (boots, power steering reservoir), brake pads, vehicle suspension, etc.;
• condition and type of road surface (presence of potholes, driving over rails, on paving stones, etc.);
• driving style (sharp braking, incorrect gear shifting);
• quality of working fluid in the power steering system.

The operating principle of a mechanical steering rack. When the driver rotates the steering wheel in any direction, the rack moves at the same time. The steering wheels of the car are turned through steering rods connected on both sides to the rack and pinion mechanism.

The mechanical rack has found wide application in passenger cars due to such characteristics as:

• simple device;
• low weight and cost;
• high efficiency;
• small number of rods and hinges;
• high response during sharp maneuvers.

It is also important that the rack and pinion steering mechanism is located perpendicular to the car, which saves space in the engine compartment for comfortable placement of the internal combustion engine and other vehicle components. Although the operating principle of the steering rack is simple, it has its drawbacks:

Although the operating principle of the steering rack is simple, it has its drawbacks:

• hypersensitivity when driving over potholes and protruding elements of the roadway with vibration transferred to the steering wheel;
• increased load on components;
• installation on passenger cars only with independent steering wheel suspension.

How to change the steering cardan

• It is better to roll the car into a pit (at least raise it in front of the car).
• Fix the steering wheel and steering wheel at a right angle. You should also not move or touch the wheels during repairs.
• Remove the front wheel, then unscrew the mounting bolt through the interior. If all operations are carried out correctly, the shaft should come off the steering wheel on its own.
• Remove both casings (top and bottom), make sure there is a boot on the steering shaft. If it is not there, it is better to install it after repair; the part costs no more than 200 rubles.
• Unscrew the bolt on the crosspiece, then the shaft will come off the steering rack on its own.
• Pull down and pull out the shaft. Before repairing, it is better to wash it from dirt and rust; it also affects the quality of movement.
• Secure the shaft in a vice. When it is secured, take the head and knock out the cross on one side to remove the bearing cup. Repeat the same action from the other end.
• Insert a new cross in the same order (one at a time on each side).
• Press in a new crosspiece with a vice (do not overpress).
• Align the cups and roll them with a hammer and chisel.
• Install the new part on the car in reverse order.

Many car owners note when they are looking for where and how to change the steering joint on a Toyota that steering crosses from the VAZ-2015 are very suitable for this brand. This greatly simplifies the process of finding parts and reduces the overall cost of repairs.

If we are talking about repairing a “workhorse”, a vehicle engaged in transportation or cargo transportation, repairs or replacements have to be made more often than once every 100 thousand km (due to the condition of most of the roads). Experienced craftsmen who give advice on how to change the driveshaft on the steering wheel of a gazelle note that it is better to install two boots at once so that the sound from the engine is quieter. At the same time, the anthers themselves can also be sealed with foam rubber rings, this significantly reduces squeaks and noise in the car interior.

The driveshaft part itself will cost from 650 rubles for domestic cars and higher for foreign cars. Plus - consumables in the form of boots and nuts.

Steering mechanism malfunctions and their elimination

The steering mechanism of the Lada Granta is quite reliable and rarely causes problems for the owner. However, this does not mean that problems do not occur at all. There are problems. And you need to know how to eliminate them.

Elimination

Like the braking system, engine operation and other important components and assemblies, the steering system must be periodically inspected for malfunctions. If there are no signs, protective boots and other smaller structural parts must be inspected. The steering rack of the Lada Granta is a key control mechanism. It is thanks to this that the car is controlled by turning the wheel.

Basic steering rack faults

The main sign of a breakdown is a knocking sound when turning. At first it is almost invisible and appears when hitting potholes. If you ignore the first symptoms, the noise will not go away and will constantly get worse. Then the knock will be transmitted to the steering wheel. If you ignore this symptom, the rack will simply jam, and this risks getting into an accident due to loss of control. The rack knocks due to wear of the hinges, teeth or rubber-metal bushings (damper).

The following symptoms can also be attributed to steering rack malfunctions.

1. The steering wheel turns hard (accompanied by a slight whistle).
2. The tight rotation stops as the speed increases.
3. With straight steering, there is no gain.
4. When turning, the steering wheel does not turn the front wheels properly (the car begins to roll left/right while driving).
5. Vibration, beating, grinding; the steering wheel begins to rattle.
6. The steering wheel does not return to its original position.
7. The steering wheel rotates spontaneously.

There are many reasons for steering rack malfunctions. But these are the most common. If at least one of them occurs, the Lada Granta should go for repairs as soon as possible.

DIY steering rack replacement

For novice motorists, this may seem like an overly complicated procedure. But in reality everything is simpler. The algorithm of actions is as follows.

1. Disconnect the battery, loosen the bolts of the front wheels, hang the front on jacks and remove the wheels.
2. Inside the car, you need to unscrew the bolt that connects the steering gear terminal to the intermediate shaft. In this case, the steering wheel must be in a straight position (the wheels are strictly straight).
3. Disconnect the rods from the swing arms.
4. Unscrew the steering mechanism mounting nuts through the gaps in the wheel arches.
5. Dismantle the clamp and remove the steering mechanism assembly.
6. Next, all anthers and their fastenings are removed.

What breakdowns may be the most common?

The most common breakdowns in the steering of any car, including Largus, can be the following:

• wear of the rack and pinion mechanism;
• leakage of the steering system itself;
• bearing failure;
• failure of the tie rod end.

The most common violation in the operation of the system is the last option. Usually, breakdowns in the steering rod do not occur on their own, but the tip is one of the most fragile parts of the car. It cannot be repaired; when it wears out, it is replaced.

A separate discussion is caused by problems with the operation of the hydraulic booster, the most common of which may be:

1. damage or loosening of hoses;
2. failure of the shaft bearing;
3. too low amount of liquid in the tank;
4. drive clogged.

Such problems can manifest themselves through malfunction of the power steering sensor, leaks of working fluids, as well as characteristic noises and knocks. If such symptoms appear, it is better not to postpone your visit to the car dealership.

Rack adjustment

Before installing the rack and rods back, it is necessary to set the gaps of the gear connection. Please note that it is better to immediately replace the thrust nut with a new one. Set the rack to the middle position, as if the wheels were straight. For adjustment, a special clock-type indicator mechanism is used. We start rotating the gear shaft and measure the indicator readings.

If the value is 0.05 mm, then the adjusting nut should be tightened to the same amount. After the steering rack adjustment is completed, check the ease and uniformity of movement along the entire length of the rack stroke. Provided that everything is done accurately, you should fix the position of the adjusting nut by performing special core punching with a punch. When all the work has been completed, you can begin to reinstall the steering mechanism on the Lada Granta. After the mechanism has been installed back on the car, you should, even before starting to drive with the car stationary, turn the steering wheel, checking the uniformity of rotation. A check that will reveal that there is no knocking can only be done while driving on a rough road.

Steering malfunctions usually occur due to insufficiently frequent preventive inspections. If the owner has missed the appearance of minor leaks in the steering mechanism, loss of integrity of the protective covers, then the likelihood that a knock will soon appear in it is quite high

Therefore, it is important to carry out annual diagnostics

How to adjust the rack?

Adjusting the steering rack involves setting the correct gap in the gear connection. We recommend replacing the thrust nut with a new analogue. The rack and pinion assembly must be set to the “zero” position, which corresponds to the straight course of the car. The adjustment is carried out using a clock-type indicator mechanism. We rotate the gear-shaft and at the same time measure the readings of a special indicator. When the value is 0.05 mm, then tighten the adjustment nut to a similar amount. Upon completion of the adjustment manipulations, we check the mechanism for ease of rotation and smooth movement of the rack in the pipe. After making sure that the steering rack adjustment was correct, we fix the nut of the same name in the specified position by punching it with a special punch.

Now we can easily install the assembled unit on the LADA Granta car. Upon completion of installation on an immobilized vehicle, rotate the steering wheel several times, checking the smooth rotation and movement of the elements. It is possible to make sure that there are no knocks only while driving over uneven surfaces. The steering rack is fine.

Comments 24

The warranty no longer applies. For this reason, remove and disassemble. We did it the first time and made a mistake during installation. Then a familiar mechanic fixed everything without removing it. The steering wheel became better than the factory one, a little more informative. A caprolon bushing, a disc spring, and a small repair kit were installed. If it can be tightened, then it’s better to do it first. Some craftsmen lie, this is allowed from the factory. If the rack has never been tightened, then most likely it should be removed.

the bushing didn't help? Hm

It’s simple, the 2190 rack on the driver’s side of the body has ebbs with ears, for which the rack is screwed to the body, but the Kalinovsky rack does not have these ears, there the rack is pressed through a clamp to the engine shield.

The 2190 rack does not have ears (I had one on Kalina). The regular one was 3.1. There was also a sports one with an index of 18. With ears, most likely the 92nd and it doesn’t cost that little. We have about 9 thousand.

I also have a 15 year old with eur. installed with article number 21920-3400010-00

thanks, I ended up with the same one

Don't be foolish and don't trust the service. There are repairs for 200.0 rubles. Just change the plastic bushing.

Can you be more specific about where it is... I have some kind of knocking noise in the cold winter (everything is fine in the summer). How does it warm up, does it?

are you talking about part number 1?

see bzh-no need to change the rack, it’s better to tune it

Look at the article number on your rack, take it off and you will see yours exactly.

This is the most accurate option. What is the mileage on the rack? I saved myself by replacing the repair kit and the bellows, and everything was ok.

it started knocking at about 60-63 thousand, and today it’s almost 73 miles. stays shorter)

I wouldn’t change it, 73 is not a big value for it, the bushing with the stop have worn out and that’s all, tightening it up will help for a week, or even a couple of days. Replace the repair kit and continue riding. At the service center they should change everything to a new one, no problems for them, no one wants to change the repair kit, it’s f...ing necessary, so they say that a new one needs to be installed, we know this, we’ve been through it more than once.

— The steering needs to be replaced, — Which steering? What exactly ?

So maybe first we should look at the bushing on the steering mechanism?

the service condemned the rake completely

Look at the bushing yourself. And then you will think whether to change the rack or not - even 73,000 km is not an indicator. Because if the service has “sentenced” the rack, then most likely the counter part also requires replacement. And this can already affect the steering mechanism assembly.

The steering mechanism in the Lada Granta consists of such a list of components and systems when the failure of any of the elements will not allow the driver to further operate the vehicle. Any malfunction that appears must be corrected immediately. In some cases, you just need to adjust the steering rack.

The steering mechanism of the Lada Granta has a rack and pinion design. This unit is quite reliable, but is not without an unpleasant feature - the appearance of a characteristic knock over time. You may also find information on how to tighten your steering rack useful.

Lada Granta 16 Valves › Logbook › We drive woodpeckers out of the steering rack (some times)

Today the recording will be a discovery for some, but for others it will be banal and a hackneyed topic. Almost a year has passed since the day when the officials told me that my steering rack had arrived because there was nowhere to tighten it further. The cost of the work was determined in the range from 15,000 to 18,000 (approximately 5,000-6,000 rubles). The amount is not large, but still the toad was pressing and it was decided to postpone the revival of the dead man. As time passed, the knocking sound on small bumps, rough patches, and ridges became stronger and more irritating. It was especially infuriating when, having loaded a completely new chassis, I rode like on a cart (I’m talking about the sounds made by the chassis). And then my friends told me a way to eradicate this knocking in a budgetary way. It consisted of inserting a plastic water pipe into the steering rack 0_o You should have seen my expression
