Replacing the driveshaft crosspiece of a VAZ 2106

The photo shows the universal joint of a VAZ 2106

Note: The driveshaft is a mechanism that transmits torque from the gearbox to the wheel drive. Used in a variety of vehicles. The main feature is a cardan transmission, invented by Gerolamo Cardano, which allows the transmission of torque between two non-parallel axes. The main working part of the cardan transmission is the crosspieces. They most often require replacement. The VAZ 2106 cardan contains two identical crosspieces. Our instructions will help you replace the VAZ 2106 crosspiece yourself; the replacement is quite simple and will allow you to save on car service costs.

Rules for choosing a cross

This is what the part looks like

On VAZ 2106, auto mechanics advise changing the crosspieces as a set. In some cases, 3 crosses are replaced at the shank. The best parts are made in Germany. Products from the following manufacturers are installed on the VAZ 2106.

Trialli with oiler. Made of steel and uniformly hardened over the entire surface. Such parts can withstand significant dynamic and statistical loads.
Kraft. Made from anti-corrosion stainless steel alloy. The manufacturer provides a warranty on the part.
Weber, GKN and other foreign manufacturers. The disadvantage of such products is the need to adjust the retaining rings.
Domestic products. Plus - affordable price.

Replacing the crosspiece on a VAZ 2106 car involves dismantling the cardan. To do this you will need an inspection hole or a jack. Removal and installation are carried out using keys “12”, “13”, “27” and a hammer.

The suspension bearing is installed using a tension puller and an old flange. The release spring is disconnected from the bracket using pliers, then it is dismantled. The cardan is jammed with a screwdriver. Unscrew the nuts and remove 1 end of the cardan. The plank and plate of the suspended structure are dismantled. The cardan is removed. The location of each part is noted so that the balancing of the shafts is not disturbed. The retaining rings are dismantled. Using a puller or vice, remove the bearing. If an anvil is used for this, then the cover of the 2nd bearing should not rest against the plane of this device.

The VAZ 2106 cardan is turned over 180°. Similar actions are carried out with the 2nd bearing. If the process is carried out without a puller, then the blows are made on the crosspiece or on the 2nd part of the cardan (with a transverse crosspiece). The bearing is pulled out of the fork. The transverse cross is disengaged. The puller is installed on the 2nd pair of bearings.

Step-by-step installation of the part

Before installation, the crosspieces are checked and lubricant is applied to the parts. For lubrication, use “Fiol” or another substance of similar effect. The bearing housing is inserted into place, the forks are pressed into place. Then the retaining rings are installed. They hit the forks with a hammer. All gaps existing between the bottom of the bearing and the ring disappear. To check the free movement of the main part, use a feeler gauge. The stroke should not exceed 0.04 mm. Otherwise, a larger diameter ring is installed.

The rings come in 5 sizes, each with its own color. If the thickness of the part is 1.5 mm, then the product is not painted.

Disassembling the cardan to remove the cross

Replacing the crosspiece involves installing a new outboard bearing. This procedure is carried out after dismantling the cardan and crosspiece. Then unscrew the front shaft nut. The puller is fixed to the fork. Using a hammer, the fork is moved and pressed from the splines. The outboard bearing fixing bolts can be unscrewed with a 13 key.

The main part is knocked out of the shaft. Reassembling the cardan is carried out in the reverse order. If the above process is carried out without dismantling the cardan, then an assistant will be required.

Lada 2106 “Red Garnet” › Logbook › Replacing crosspieces

Good day to all!

Yesterday we replaced the universal joint crosspieces. Due to noise during gear shifting. As it turned out, the bearings on the crosspiece were worn out.

How to determine crosspiece wear

If, when lowering the pedal, when shifting gears, or during sudden acceleration or braking, you hear a knocking sound in the cardan drive, vibration of the axle, this indicates severe wear of the crosspiece and bearings. It is urgent to carry out work to replace these worn-out parts. You can, of course, ignore the symptoms, but then there is a high probability that the bearing will collapse and the cardan will fall out someday right on the road. The gearbox may also be damaged.

You should have the following tools at hand: open-end wrenches 12 and 13, a copper or aluminum adapter, compression pliers, a hammer, a socket wrench 13 and 27. If it becomes necessary to replace the outboard bearing, you will need a tension puller and an old flange of the elastic coupling.

Removing the cardan on a VAZ 2106 Sequence of actions when removing the cardan

Using round nose pliers or pliers, disconnect the tension spring from the body bracket and remove it.

Mark with paint the joint between the gearbox flange and the cardan (this will be useful during assembly). Having jammed the cardan with a screwdriver so that it does not turn, unscrew the self-locking nuts (there are four of them) with a No. 13 wrench.

After the nuts are unscrewed, one end of the cardan can be easily removed.

The relative location of the elastic coupling flange and the cardan should also be carefully noted.

Bend back the 4 locking tabs on the seal ring near the elastic coupling.

Carefully move the cage towards the cardan (together with the seal).

Using a 13mm socket, unscrew the two nuts and remove the safety bar.

Using a 13mm wrench, unscrew the two nuts and remove the plate of the outboard bearing, secured to the body through rubber washers, from the studs that secure it to the body.

Remove the cardan shaft from the splines of the flexible coupling flange and remove it.

Which crosspiece is better to install?

Car service specialists say that if the time has come to change the crosspiece, then it is better to change them as a set, both of them. In fact, this is not always the case. The front crosspiece, as a rule, lasts much longer than the rear one. Sometimes three crosspieces are replaced at the shank, but at the outboard bearing the crosspiece remains fully functional.

Experts advise not to “kill the ears of the cardan”, and not to change the crosspiece unless necessary.

When purchasing, you should not save on cost, it will be more expensive. Quite good crosspieces made in Germany are of high quality and come complete with retaining rings, which come in very handy if the “original” ones break during disassembly.

Trialli reinforced crosspieces (with an oiler at the end of the tenon) - made of high-carbon steel, uniformly hardened over the entire surface. Withstands high static and dynamic loads. The improved seal design provides reliable protection from sand and dust to the bearing units.

The crosspieces (with oiler) are made of a special stainless steel alloy that is resistant to corrosion. The manufacturer guarantees high quality based on multi-stage control during the production process.

Crosspieces from Weber, GKN, etc. The only disadvantage of imported crosspieces is that the retaining rings often need to be adjusted.

Installation of crosspiece VAZ 2106

First, you should check the presence of lubricant in the new crosspiece on the inner surface of the bearing housings and the spikes of the crosspiece. If necessary, lubricate the crosspiece bearings with Fiol. Place seals and plastic plugs on the crosspiece. Insert the spider spikes into the fork. Place the bearing housings and press them into the fork holes. The bearing should go deeper than the groove for the retaining ring. Install retaining rings. Tap the forks with a hammer (preferably one with a plastic striker). The gap between the bottom of the bearing and the retaining ring is eliminated under the influence of impacts and gaps will appear between the ends of the crosspiece studs and the bearing housings. Use a feeler gauge to check the axial free play of the crosspiece - it should not exceed 0.04 mm. If the axial stroke is greater, replace the ring with a larger diameter. Retaining rings are available in five sizes. For clarity, each size has its own color. Rings with a thickness of 1.5 mm are unpainted, 1.52 mm are dark brown, 1.56 mm are blue, 1.59 mm are black, 1.62 mm are yellow. Check the balancing of the cardan drive and the ease of rotation of the hinge forks.

Malfunctions of the VAZ 2107 driveline

You can determine that the VAZ 2107 driveshaft is faulty by the following signs:

Knocking sound after engaging the clutch. The cause of the knocking may lie in a poorly tightened universal joint drive, worn splines, damaged elastic coupling, or failed crosspiece bearings.
Grinding noise when the car is moving. This sound occurs when the cardan joint bearings (crosspieces) are heavily worn.
Vibration of the cardan when driving. This phenomenon occurs when there is mechanical damage to the driveshaft or dirt adheres to the driveshaft, which disrupts its alignment. Vibrations also occur when there is significant wear on the gearbox driven shaft, outboard bearings, cardan crosspieces, drive gear flange of the rear axle gearbox, or loose fastening of the cardan drive.
Knocking noise during sudden acceleration or engine braking. The reason for this lies in the wear of the cardan shaft crosspieces.

You can check the condition of the cardan drive by placing the machine on a lift or inspection hole. The transmission parts should not play when the cardan is “rocked” in different directions.

To eliminate malfunctions, it is necessary to replace the VAZ 2107 driveshaft crosspiece, coupling, and other damaged parts.

VAZ 2106 replacing the crosspiece yourself

How to diagnose wear on crosspieces

Replacing the crosspiece in a VAZ 2106 is carried out after diagnostics:

When, during rapid acceleration or braking of a car, when changing gears, a knocking sound from the cardan transmission or vibration of the axle is heard, all this indicates wear of the crosspiece and its bearings. There is an urgent need to replace the VAZ 2106 crosspiece, which has become unusable.
If you don’t pay attention to these signs in time, then the result will be destruction of the bearing and the cardan falling out directly onto the road. The axle gearbox and the underbody of your car can also be damaged.

Buy a “VAZ” crosspiece, do not forget to purchase spare retaining rings (if they are not included in the kit), because old rings, as a rule, become deformed or break.

Tool required for replacement

Replacing the driveshaft crosspiece of a VAZ 2106 requires the following tools:

Two open-end wrenches 13 and 12
Socket wrenches 27 and 13
Copper or aluminum extension
Hammer
Compression pliers with thin jaws to remove circlips
Two mandrels for pressing out the cardan cross bearings.
Universal puller
Ticks
Chisel
Large screwdriver

We remove the cardan

Replacing the VAZ 2106 crosspiece with your own hands is not possible without removing the cardan from the car. So:

We remove the cardan on a lift or inspection hole. Unhook the handbrake cable spring.
Using a chisel, we apply marks at the junction of the cardan and the gearbox flange. Using a 13mm wrench, unscrew the nuts (there are four of them). Use a large screwdriver to secure the cardan shaft from rotating.
Remove the rear end of the cardan.

Disconnect the cardan from the bridge

Use a chisel to mark the position of the cardan and flange of the rubber coupling

Mark the position of the cardan and flange with a chisel

Then we bend the locking tendrils of the seal ring near the rubber coupling
We move the cage with the seal together towards the propeller shaft

Using a 13mm socket, unscrew the nuts and take out the safety bar
Supporting the cardan, unscrew the nuts using a 13mm wrench and remove the plate securing the outboard bearing from the studs. It is attached to the body using rubber washers.

We pull the cardan out of the slots inside the rubber coupling flange and take it out

It is first recommended to watch how to replace the crosspiece of a VAZ 2106 video.

How to replace a driveshaft bearing?

In order to change the propeller shaft bearing , it is enough to knock out the old bearing, after first removing the retaining ring. And slowly hammer the new bearing into place.

“When you choose a driveshaft crosspiece, it is better to give preference to the VAZ crosspiece”

1)Buy a cardan shaft crosspiece;
2)Buy retaining rings.

How to buy a driveshaft crosspiece for VAZ 2106, VAZ 2107, VAZ 2101, VAZ 2105, VAZ 2102, VAZ 2104?

Before buying a driveshaft crosspiece , you should go through two stages, the first is to select a driveshaft crosspiece and check the driveshaft crosspiece.

I decided to write down information on how to buy a universal joint for a driveshaft because of frequent requests on the Internet about: What are the best manufacturers of universal joints? What are the quality crosspieces? How to buy a high-quality driveshaft crosspiece? How to determine if the driveshaft crosspieces are defective?

Let's look at a list of reliable and inexpensive crosspieces for the VAZ 2106, VAZ 2105, VAZ 2107, VAZ 2101, VAZ 2102, VAZ 2104, VAZ 2103 (Fig. 1).

1) GKN cardan shaft crosspiece is a German-made crosspiece, characterized by good quality and a fairly inexpensive price. I advise you to install such a crosspiece on newer cardans, since when installing a crosspiece on a tired cardan, the crosspiece will also wear out quickly.
2)The AvtoVAZ driveshaft crosspiece is produced in Russia in the city of Togliatti. It has excellent quality and price. I would buy a cross from AvtoVAZ.
3)VolgaAvtoProm driveshaft crosspieces are also good crosspieces, but you should pay attention when purchasing and take time to check the driveshaft crosspiece.

Checking the driveshaft cross

You can check the driveshaft crosspiece using a regular mirror. Place the mirror on the table surface and place the cross on top. Take the propeller shaft crosspiece by the ends and rock it, checking for any play. If, when checking the crosspiece using a mirror, slight play and knocking are observed, then such a crosspiece can also be installed, but slight vibration will be observed, which is not very pleasant.

Tool for replacing the crosspiece and the outboard bearing of the propeller shaft of VAZ-2101, VAZ-2102, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107 (Fig. 2).

Replacing the driveshaft crosspiece on a VAZ 2106

We first mark the relative positions of the parts (cardan joint forks) so as not to disturb the factory balancing of the cardan shaft during assembly.
Then we mark the locking rings and their seats in order to install them in their standard places during assembly. Remove the retaining rings (four from each hinge).

We take out the locking rings

We press the bearings out of the hinge fork using mandrels of a suitable diameter.

Since the bearings are not pressed in completely (the joint cross rests against its fork), we remove the bearing using pliers
We disconnect the cardan joint by moving its crosspiece in the direction of the removed bearing, slightly turn the crosspiece and remove it from the hinge fork.

Press the opposite needle bearing out of the hinge fork.
We carry out steps 3 and 4 for other needle bearings and remove the cross.
We do the same with the second cross if necessary.

As you can see, replacing the crosspiece on a VAZ 2106 with your own hands is not particularly difficult.

If necessary, replace the intermediate bearing

Unlock the nut securing the front shaft fork. We unscrew it and press the fork using a puller from the front shaft.

Remove the dust deflector from the front shaft.
Screw the nut onto the threads of the front shaft so that it is flush with the shaft itself
We compress the intermediate shaft support (we apply force to the inner race of the bearing) and unscrew the nut.
Remove the support along with the bracket from the propeller shaft

Tip: Remember the position of the arms - the long and short support bracket relative to the driveshaft (it is better to mark the position of the support bracket relative to the driveshaft).

We unscrew the bolts securing the bracket to the support, remove all the washers and disconnect the bracket from the intermediate shaft support.

Advice: Disassembling the intermediate support requires special tools and certain skills, therefore, it is recommended to change the intermediate shaft support assembly.

Defective parts

We thoroughly clean the parts with a brush before inspecting them.
To cull the cardan transmission elements you will need: a bore gauge, a dial indicator.
Since we have removed the cardan and disassembled it (albeit partially), we check the integrity of the welds. Drive shaft splines so that they do not contain wear marks
For the rear cardan shaft, we check the presence of balancing weights, the condition of the seams and measure the diameters of the fork holes for the needle bearing. Dents of pipes and misalignment of the holes of the cardan forks are not allowed.

Important: Be sure to measure the diameter of the holes in the universal joint forks, where the needle bearings go, so that it does not exceed 23.825 millimeters. Measurements are made with a dial gauge.

We check the condition of needle bearings, oil seals, their cages and spider spikes for damage and significant wear.

Note: A clear sign of a defect in the studs, upon detection of which the entire joint is replaced, are longitudinal dents left by the bearing needles.

At the same time, check (while the cardan is removed) the condition of the rubber coupling of the cardan.
The presence of cracks, mechanical damage or detachment of rubber from steel liners is not acceptable.
We check the intermediate support for deformations. Cracks or ruptures of the elastic clip, as well as peeling of the rubber, are not acceptable. Replacing the defective support assembly
We check the intermediate support bearing, rotate its inner race in two directions, while pressing it against the outer race (the inner race should rotate smoothly). We check the bearing seals for mechanical damage.
We replace all defective parts.

We assemble the cardan in the reverse order, taking into account the features given below:

Before installing the front shaft fork, lubricate the splines of the fork and shaft with grease.
When installing the front shaft fork, tighten the nut securing it with a torque wrench 8.1-10 kgf•m (79.4-98 N•m) and tighten the nut with a chisel.
When installing the oil seal race, the oil seal itself with the flange onto the front driveshaft splines, we fix the oil seal race by bending its three “tendrils”.
Using an oil syringe, coat the splined part of the front driveshaft. Remove excess grease with a rag. We unscrew the grease nipple and screw in the plug in its place.

Which suspension bearing and crosspiece should I install on the VAZ Classic?

The original number of the outboard bearing is 2101-2202080, the average price is 330 rubles.

SEVI 3103 — 426 rub.
Trialli RM0133 — 471 rub.
Master-sport 2101-2202080-ST-PCS-MS — 506 rub.

The original number of the cross is 2101-2202025, the average price is 260 rubles.

Trialli CC506 — 212 rub.
Toyo TU-51L — 350 rub.
Zommer 21012202025 — 210 rub.

The parts needed for replacement are the bearing, spider and snap rings.

The set of tools is as follows: open-end wrenches for 12 and 13, socket wrenches for 13 and 27, pliers for removing retaining rings, a puller and an elastic coupling flange for replacing the outboard bearing, as well as a hammer and an adapter made of aluminum or copper.

Let's move on to removing the driveshaft from the car. Unscrew the nuts securing the propeller shaft to the rear axle shank.

First, using a 13mm wrench, unscrew the two bolts securing the suspension bearing to the transverse support.

After the cardan has been removed, not all of its parts need to be marked, so that in the future it can be assembled according to the applied marks in order to avoid its beating and vibration.

We change the cross. Using pliers, remove all retaining rings.

The cardan shaft must be installed in such a way that the crosspiece is suspended. Using a hammer and a mandrel, knock out the cup of the cross. A puller for cardan shaft crosspieces will allow you to do this faster and safer.

We unfold the cardan and take out the cup.

We repeat the same with the remaining cups of the cross, after which the eyes of the propeller shaft are cleaned of dirt and rust, as are the grooves for the retaining rings.

Remove two cups from opposite sides of the crosspiece and tuck the crosspiece into the eyes. Carefully, so as not to scatter the needles from the cup, move it to one side and put the cup on.

Using a soft metal adapter, we seat the cup until a groove for the retaining ring appears. Having installed the retaining ring, turn the cardan over. Carefully move the cross to meet the cup and put it on, in the same way we seat it until a groove appears. We install the retaining ring. The second part will be a little more difficult to assemble. The crosspiece has been replaced.

We are replacing the driveshaft outboard bearing. After removing the crosspiece, insert the splined end of the cardan into the flange of the elastic coupling.

From the other end, using a 27mm wrench, unscrew the nut securing the universal joint fork to the front shaft.

Use a puller to tighten the hinge fork.

after which we remove the outboard bearing from the shaft, for which you can use a puller after cutting off the outer ring of the outboard bearing. Or just try to knock him off the shaft. That's all, assembly is carried out in reverse order.

Purpose of the VAZ 2106 cardan cross

When a car is moving, the axles of the vehicle are not always on the same straight line. They change their position relative to each other and the distance between the axes also changes. On the VAZ 2106, as on many other cars, torque from the gearbox to the rear axle is transmitted through a cardan, at the ends of which crosspieces (hinges) are installed. They are the main link of the cardan transmission, which connects the gearbox and the drive gear of the rear axle gearbox. Another important function is assigned to the universal joint crosspiece - the ability to dampen possible deformation of the universal joint due to the constant movement of all its elements.

What are cardan crosspieces made of?

Structurally, the universal joint is made in the form of a cross-shaped part with needle bearings, seals and covers, which are fixed with a stopper.

Cross

The cross itself is a product with perpendicular axes in the form of spikes, supported by bearings. The material used to manufacture the part is high-alloy steel, which has high strength. Such properties allow the crosspiece to withstand heavy loads for a long time.

Bearing

The outer part of the bearings is a glass (cup), the inner part is a spider spike. The movement of the cup around the axis of the tenon is possible thanks to the needles located between these two elements. To protect the bearing from dust and moisture, as well as to retain lubricant, boots and cuffs are used. In some designs, the end of the crosspiece tenon rests against the bottom of the cup through a special washer, which is a thrust bearing.

Stopper

Bearing cups in the holes of forks and flanges can be fixed in different ways:

retaining rings (internal or external);
clamping strips or covers;
punching.

On a VAZ 2106, a retaining ring secures the bearing cup from the inside.

What does it look like

Let's first look at what rear and front driveshaft crosspieces, or rather their installation methods, are used:

Crosspiece installed by punching.
Retaining rings (internal or external).
Locking caps.

The first type of replacement and installation is usually most common on passenger cars with rear-axle torque transmission, all-wheel drive crossovers, and light commercial vehicles. Factory assembly method, until some time the unit was considered non-separable, the part was sold assembled. During the replacement process, the driveshaft crosspieces are fixed by point-shifting the inner part of the fork metal onto the needle bearing cup.

The second and third types are found everywhere to a greater or lesser extent.

Which crosspieces to put on the “six”

If you listen to the opinion of service station specialists, they recommend replacing both universal joint crosspieces, even if only one of them fails. But not everything is so simple. The crosspiece located at the front of the driveline travels much longer than the rear one. There are situations when a part in the shank is changed three times, but near the outboard bearing there is no need to replace it. When choosing crosspieces for your car, you should not chase a low price, since repairs will ultimately cost more. Let's look at some hinge manufacturers that you can trust with your choice:

Trialli. Made of high carbon steel and evenly hardened over the entire surface. The product is able to withstand high impacts of dynamic and static nature. The seal has an improved design, which increases reliability and protection against dust and sand getting inside the bearings.

Before purchasing and installing a universal joint, be sure to consider the size and shape of the cups. Attention should also be paid to the hinge pins. They should not have any burrs, marks or other defects. For domestic cars, it is better to give preference to crosspieces with a grease fitting, i.e., serviceable ones, which will allow you to periodically renew the lubricant in the bearings. The seals must not have any defects, such as visible tears or manufacturing defects.

Table: parameters of the universal joint for the “classic”

Number	Application	Dimensions DxH, mm
2101–2202025	Cardan crosspiece VAZ 2101–2107	23.8x61.2
2105–2202025	Cardan crosspiece VAZ 2101–2107 (reinforced)	23.8x61.2

Signs of faulty crosspieces

The VAZ 2106 crosspiece, like any other car part, has a certain service life. Theoretically, the service life of the part is quite long, about 500 thousand km, but the real figures are 10 times less. Therefore, replacement has to be carried out after 50–70 thousand kilometers. This is due not only to the quality of the parts, but also to our roads and the intensity of vehicle operation. Lack of periodic maintenance of crosspieces only brings the need for their replacement closer. The following characteristic signs indicate that there is some problem with the hinge:

blows and knocks;
chassis vibrations;
squeaks when driving or accelerating.

Clicks and bumps

Often problems with crosspieces appear when the seals are damaged and dust, sand, dirt and water get inside the bearings. All these factors negatively affect the service life of the product. When the joints wear out, clicks will be heard when changing gears while moving, impacts at a speed of about 90 km/h, and a crunching or rustling sound will also appear. If metallic sounds occur, it is recommended to twist parts of the cardan, for example, by placing the car on an overpass. If large play is detected, the crosspieces will need to be replaced.

When diagnosing the gap in the crosspieces, the gearbox must be in neutral gear.

Video: play of the cardan cross

If clicks appear in the cardan area on my car, but I am sure that the crosspieces are still in good condition and should move, then, most likely, there is simply not enough lubrication in the hinges, for which they need to be injected. If clicks appear, I advise you not to delay maintenance, since the bearings will break and it will no longer be possible to do without replacing the crosspiece.

Creaks

The cause of squeaks in the area of the driveshaft is usually associated with souring of the crosspieces. The problem is clearly noticeable at the beginning of the movement and when driving at low speed, while the car creaks like an old cart.

The malfunction occurs when the hinges are not maintained, when the bearing simply cannot cope with its task. Sometimes, after removing the cardan, it is discovered that the crosspiece does not move in any direction at all.

Video: how the cardan cross creaks

Vibration

Malfunctions in the form of vibration with the universal joints can occur when moving forward or in reverse. The problem can be present with both old bearings and new ones. In the first case, the malfunction is caused by jamming of one of the hinges. If the vibration persists after replacing the crosspiece, then a low-quality part may have been installed or the installation was performed incorrectly. The crosspiece, whether old or new, should move in any of the four directions freely and without jamming. If you have to exert little effort when moving the hinge by hand, you can lightly tap the bearing cup; it may not be seated properly.

Replacing the outboard bearing

After the cross has been removed, the outboard bearing needs to be replaced. To do this, use the “27” key to unscrew the nut of the front cardan fork. After tapping the fork on all sides, release it from the slots. The bearing is held on the shaft by two “13” bolts; after unscrewing them, you should set the suspension on the corners and knock it out with a hammer.

Installation of all elements is carried out in reverse order. After installing the propeller shaft in its place, you need to make sure that all the bolts and nuts are securely tightened, and you also need to immediately check the play.

With proper repairs, there should be no backlash, and when driving at speeds above 90 km/h, there should not be the slightest vibration emanating from the driveshaft. The crosspiece should be filled with oil every season.

How much will this procedure cost at a car service center?

The average price for a crosspiece replacement service is 500 rubles. If any related difficulties arise, the cost increases. It is often suggested that the outboard bearing be replaced immediately, as this will be much cheaper than replacing these parts separately. On average, they require 1000 rubles to replace an outboard bearing.

How to replace the driveshaft crosspiece of a VAZ 2107 (video)

The serviceability of the driveshaft crosspiece directly affects the operation and resource of the entire transmission, as it plays the role of a flexible connector between the engine and the rear axle. Timely maintenance and replacement will significantly extend the life of the VAZ 2107 transmission. This replacement operation can be performed using the repair manual and with a minimum of tools. The main thing in repairs is to be careful and follow the procedure so that the life of the car is as long as possible.

Replacing the VAZ 2106 universal joint

The cardan crosspieces must only be replaced, since the bearing needles and the outer and inner parts of the race wear out, which leads to the formation of play. This indicates the impossibility and inappropriateness of restoring the part. If characteristic signs indicate that the cardan joints need to be replaced, you will need to dismantle the shaft itself, and then begin repairs. For the upcoming work you will need the following tools and materials:

open-end wrench 13;
head 13 with a knob or ratchet;
copper or aluminum extension;
hammer;
compression pliers with thin jaws;
universal puller;
chisel;
new crosspiece;
lubricant “Fiol-1” or “CV joint-4”;
large screwdriver.

Removing the cardan

On the VAZ “Six” the driveshaft is mounted to the rear axle gearbox, and closer to the gearbox the driveshaft is held by an outboard bearing. Removing the shaft from the car is carried out as follows:

Unscrew the cardan mount with a 13 key.

Removing the cross

After dismantling the driveshaft, you can immediately begin disassembling the crosspiece:

We mark the universal joint forks to avoid disturbing the factory balancing during assembly. To apply marks, you can use paint (pictured below) or hit it lightly with a chisel.
We remove the retaining rings using special pliers.

Installing the crosspiece and cardan

The cardan crosspieces are filled with lubricant from the factory. However, when replacing a product, I always syringe the hinge after the repair. There will be no excess lubrication, and its lack will lead to increased wear. For crosspieces, it is recommended to use “Fiol-2U” or “No. 158”, but in extreme cases “Litol-24” will also do. Although I know car owners who use Litol for both crosspieces and spline joints. When injecting, I pump the lubricant until it begins to come out from under the seals. According to the regulations, the hinges must be serviced every 10 thousand kilometers.

You don't have to be an experienced auto mechanic to replace universal joints. The desire of the car owner and step-by-step instructions will help identify the malfunction and carry out repairs in a garage without making mistakes.

Replacing the VAZ 2101 crosspiece - dismantling

1. First of all, you need to remove the propeller shaft, to do this you need to use a “13” key to unscrew the two bolts securing the outboard bearing to the transverse support.

2. At the junction of the rear axle shank with the cardan, unscrew the fastening nuts. I recommend putting labels, just in case, so that it will be easier later and so as not to confuse anything. This will allow you to avoid possible problems in the form of beating and vibration of the cardan, which sometimes arise if the cardan is assembled differently from how it was installed.

3. Dismantle the cardan shaft crosspiece; to do this, using special pliers, remove the retaining ring.

Rotate the cardan so that the cross is in a hanging position.
Now, using a hammer and a mandrel, you need to knock out the cup of the cross.

Remove the cup, to do this, turn the cardan, then knock it out again in the same way.
Prepare the propeller shaft eyes before replacing the crosspiece, clean the surface from all kinds of dirt and corrosion, and pay attention to the grooves for the retaining rings.

How to change the crosspiece 2106 with your own hands

In the article you will learn for what purposes the 2106 crosspiece on the cardan shaft is needed, as well as how to replace it with your own hands. The Six is one of the few cars that can be repaired independently, without the help of specialists at service stations. Unfortunately, everyone tries to earn as much as possible, and mechanics are no exception. Along with replacing the crosspiece, they will force you to install a new driveshaft, and this significantly increases the cost of service. Moreover, you can also run into “black” craftsmen who will include in the cost of repairs those items that were not actually completed. But we have moved away from the topic of conversation, let's still look at how a car is repaired.
