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.

Driveshaft VAZ 2106

The cardan transmission consists of two tubular shafts connected to each other by a universal joint, an elastic coupling and an intermediate support. The front driveshaft is made of a thin-walled pipe, with splined ends welded to both ends. A flange is placed on the splines of the front tip, which is fastened to the flange of the secondary shaft of the gearbox with six bolts through a rubber coupling. The alignment of the connected shafts is guaranteed by the centering ring 15, pressed onto the end of the secondary shaft, and the centering sleeve, pressed into the flange of the propeller shaft.

Replacing the cross

Sequence of actions when replacing crosspieces

The cardan has been removed. Once again, we emphasize that it is necessary to mark the relative positions of the parts with paint or a chisel, so as not to disturb the balancing of the shafts. Using pliers, remove the retaining rings.

Install the puller and press the needle bearing into the puller cup. If there is no puller, you can fix the driveshaft in a vice or place it on an anvil, but so that the opposite bearing cover does not rest against the plane of the anvil or the vice. While carefully tapping the cap of one of the bearings (a drift with a hammer), follow the opposite one.

The bearing should extend 1/3 of the way.

Turn the cardan 180 degrees and begin a similar operation to press out or knock out the second bearing. If the work is carried out without a puller, please note that you need to hit not on the cover, which already protrudes half a centimeter, but on the cross itself or on the second part of the cardan on which the cross member is held. After the second cover appears above the surface with the same protrusion half a centimeter, you can remove them using cobra pliers or, resting a screwdriver on the edge of the bearing housing, knock the pressed bearing out of the fork.

Release the cross member from its engagement.

Install a puller for the other pair of bearings.

Experienced car owners often do not remove the cardan to replace the rear crosspiece, but only unscrew the cardan from the axle. To do this, you need an inspection hole and, preferably, an assistant. If you have little experience in car repairs, it is better not to resort to this method.

Installing the clutch basket follow the link.

Malfunctions

If a howling or whistling sound occurs while the vehicle is moving.

Check the condition of the vehicle's propeller shaft support bearing.

The cardan shaft is out of balance; this can be due to mechanical damage, distortion, or a build-up of dirt on the surface of the shaft.

Severe wear or damage to the centering sleeve of the flexible coupling flange and the centering ring of the transmission secondary shaft.

Wear of the support bearing or increased clearance in the bearing, which led to the formation of whistling and howling of the cardan shaft.

The bearings of the cardan joints are worn out and may become jammed.

There is an imbalance in the cardan shafts.

Insufficient lubrication of the spline joint, check and lubricate if necessary, use LITOL-24 lubricant.

Perhaps the problem is in the elastic coupling, or rather, the flange seal ring has weakened.

What to do if a lubricant leak occurs?

Wear of the seal or loosening of the seal ring of the flexible coupling flange. It is also possible to loosen the nuts securing the elastic coupling.

Severe wear or mechanical damage to the universal joint seals.

In the front propeller shaft, the spline clearance has been greatly increased.

Severe wear and, as a result, a fairly increased gap in the bearings of the cardan joints.

Deformation of the cardan shafts is also possible.

Suspension bearing

To replace the crosspiece and suspension bearing on cars you will need: open-end wrenches 12 and 13, socket wrench 13 and 27, an aluminum or copper adapter and a hammer, compression pliers for removing the retaining rings, a tension puller, an old flange of an elastic coupling. You will need a puller and flange if you are replacing the driveshaft outboard bearing.

Note:

When reinstalling the elastic coupling (if it was removed during repairs), the liners 2 must coincide with groove 3 located on the flange of the front propeller shaft and groove 1 located on the flange of the secondary gearbox shaft.
When free, the outer diameter of the coupling increases, which is why the new coupling set includes a turnbuckle. It must be removed after completing the installation of the cardan transmission. If you still don’t have a clamp, you can use a punch to align the bolt holes in the flanges and coupling.

Description of design

The cardan transmission consists of front and rear cardan shafts, an intermediate elastic support, an elastic coupling, a movable spline joint and two cardan joints. The presence of two universal joints and a spline connection makes it possible to transmit torque from the gearbox to the main gear at an angle that constantly changes during suspension operation. Cardan shafts are made of thin-walled steel pipe. The front shaft has splined ends at both ends, and the rear shaft has universal joint forks. The elastic coupling is designed to absorb vibrations and jerks in the driveline. It connects the gearbox and the front driveshaft through two flanges. Their alignment is ensured by a centering ring on the gearbox shaft and a centering sleeve in the propeller shaft flange. The intermediate support consists of a radial ball bearing mounted in a bracket inside a rubber insulating pad. The bracket is secured to the body using a cross member through vibration-isolating bushings. The cardan joint consists of two forks mounted on shafts, which are connected to each other by a cross. The hollow spikes of the crosspiece are fitted with needle bearings with sealing collars. The bearings are secured in the forks with retaining rings. Currently (since 1988), cardan shafts are equipped with hinges of increased durability. They are equipped with crosspieces with spikes of increased diameter, stamped needle bearing housings, radial-end type seals without a metal clip and a fork of increased thickness. Modern and previously produced crosspieces are interchangeable, but installing “new” crosspieces into the forks of “old” driveshafts is not recommended, since this reduces the overall rigidity of the joints. Below we consider the technology for replacing only the hinges currently installed.

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.

Note: It is not necessary to replace the grease fitting with a plug. It’s just that when you re-lubricate the spline joint, you will have to thoroughly clean the oiler from adhering dirt.

Lubricate the needle bearings and stud surfaces of the universal joint with grease.

Tip: We recommend using grease (purple) for bearings containing molybdenum disulfide.

Having installed the bearing races, we determine the gaps between the end part of the bearings and the upper edge of the annular groove located on the hinge fork using a flat feeler gauge. The permissible gap is within 1.5-1.66 millimeters.
We select the thickness of the locking rings based on the obtained gap values (we measure the rings with a micrometer).
After installing the rings, we apply a couple of blows with a rubber hammer to the hinge forks from the reverse sides (this ensures the contact of the needle bearing races with the locking rings and the free movement of the cross).

That's all, all that's left to watch is: Replacing the crosspiece on a VAZ 2106 video.

Note:

Special tapered head bolts and fast wearing bald nuts with a nylon ring secure the universal joint flange together with the pinion flange. If the bolt turns, you need to fix it with a screwdriver.

Unscrew the 2 nuts connecting the cross members of the intermediate support and the body of the VAZ 2106. Remove the washers.
Remove the cardan drive by moving it in the direction of travel of the vehicle. At this time, the rear shaft should pass above the handbrake cable.

Assembly is performed in reverse order.

Replacing the driveshaft crosspiece in a VAZ 2107 2105 2106 with your own hands.

Today we will learn with our own hands how to quickly and correctly replace the driveshaft crosspiece on VAZ cars of the classic family, such as VAZ 2107, VAZ 2105, VAZ 2106, etc.

We drive into the inspection hole, as in our case, or lift the car on a lift. Unscrew the 4 bolts on the cardan shaft:

We unscrew the two bolts on the suspension bearing (a 12 or 13 wrench, depending on which bolt you have):

We dismantle the cardan. We wrap the splined part with a clean rag to prevent sand and other dirt from getting there. We tap through the mandrel:

We pull it out using pliers:

We select a suitable mandrel and press out the old cups through it:

The last part is knocked out with a hammer. We clean the seats from sand and dirt with a metal brush, carefully clean all the grooves with a screwdriver, and lubricate them. Installing a new driveshaft crosspiece:

We use round-nose pliers to install new locking rings (they come complete with a new cross):

We check the work by rocking it in each direction. The crosspiece should rotate equally left and right, up and down. If one of the sides rotates worse, then when you put the driveshaft on the car you will feel vibration. One of the sides rotates tighter, so we remove the retaining ring from this side and grind it down with sandpaper to make it a little thinner:

After turning and reinstalling, the flange began to move easily in each direction, it can be easily moved with a finger. At the same time, we check the suspension bearing, twist it, make sure there is no noise or play, the rubber band should be intact and not torn.

When replacing the middle crosspiece, mark the cardan with the half-cardan with chalk so as not to confuse it. The removal process is identical to the rear crosspiece:

The video shows the process in full. Before installing the cardan, lubricate its splined part with nigrol.

Replacing the cardan on a VAZ 2101-VAZ 2107 - Vaz-Russia.ru

29 Nov 2014 — Replacement of the driveshaft for VAZ 2101, VAZ 2102, VAZ 2103, VAZ 2104, VAZ 2105, VAZ 2106, VAZ 2107.

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.

Recommendations:

When working with a lift, it is necessary to hang the rear wheel so that the cardan drive rotates more conveniently; if the car is parked on a viewing hole, secure the wheels with wheel chocks.

Lower the parking brake lever and leave the shift knob in the neutral position.

Remove the nuts that secure the safety bracket to the body, remove the lock washers and flat washers, and remove the bracket.

While rotating the propeller shaft, remove the flange and coupling bolts (this can only be done when the bolt is located in the upper left corner in relation to the coupling axis). If they are tight, you can use a beard.

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”

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.

Vibrations in the driveshaft may be due to imbalance. The reason may lie in the impact on the cardan with something hard, for example, when hitting a stone. The balancing plate could also fall off the shaft. In such situations, you will have to visit a car service to eliminate the imbalance, and possibly replace the shaft itself.

Cardan vibrations are caused not only by the failure of the crosspiece. From personal experience I can say that the problem also manifests itself when the outboard bearing breaks, when the rubber in which it is held breaks off. The vibration is heard especially clearly when reversing and when starting to move in first gear. Therefore, before you start replacing the crosspiece, it would be useful to check the driveshaft support.

Features of the mechanism

The driveshaft transmits the torque generated by the car's engine to the rear axle, causing the wheels to rotate. It is located under the bottom of the VAZ-2107 car, which is why you can find a raised floor in the cabin.

The cardan on the VAZ 2107 consists of two main parts, which are connected to each other using a cross. This design of the device is necessary because the rear suspension constantly “plays” when driving due to shock absorption. The device is a hollow tube, which is the “arm” connecting the engine to the wheels. Despite the simplicity of the product, the shaft, like other car parts, fails and requires repair or replacement.

Main cardan malfunctions

The main malfunction of the driveshaft is that elements such as the spider and the outboard bearing fail. It is these parts that are the most loaded. The crosspiece and bearing fail for a simple reason - lack of lubrication. Over time, it is necessary to periodically diagnose these elements with the obligatory addition of lubricants. In rare cases, a cardan malfunction may be associated with a defective crosspiece, which requires its replacement.

The malfunctions of the mechanism in question are as follows:

failure of crosspieces;
destruction of the outboard bearing;
violation of the configuration (imbalance) of the shaft;
breakage of flanges, splines and couplings, which happens under heavy loads;
excess moisture and dirt inside the crosspieces.

At the slightest sign of malfunction, it is necessary to diagnose the mechanism and eliminate all resulting damage. The malfunction can be identified by the following signs:

the appearance of a knocking sound when the clutch is engaged, which may indicate wear of the splines or damage to the elastic coupling;
the occurrence of a grinding noise when the car is moving indicates a lack of lubrication;
the appearance of vibration when the car is moving, which indicates a violation of the alignment of the product;
knocking noise during sudden acceleration or braking, which indicates wear of the crosspieces.

We will discuss how to replace the VAZ 2107 driveshaft in the next paragraph.

The process of removing and replacing the cardan

The mechanism is removed for the purpose of carrying out repair work or replacing it with a new product.

Often the driveshaft itself is an unpretentious device, but it is important to periodically check the condition of the bearing, splines and crosses. These are the weak points that need to be periodically looked at and monitored for their condition.

Work on dismantling the cardan is carried out in the following order:

First, you need to secure the car by placing stops under the front wheels, and place the gearshift lever in the “neutral” position. Next, jack up the rear of the car, while suspending one of the drive wheels. We proceed to disconnect the device from the mount to the differential. To do this, you need to unscrew the 4 fastening nuts and then remove the bolts. After unscrewing the fastener, you can separate the product from the differential flange.

It remains to unscrew the two nuts securing the cross member on which the suspension bearing is mounted. After unscrewing, you can dismantle the cardan from the VAZ 2107. Using a wooden hammer, you need to knock out (if necessary) the shaft from the engagement of the splines with the elastic coupling. After the shaft is repaired or replaced, you can install it in place. The installation process is inversely proportional to removal

When installing the product, it is important to ensure that the shaft is positioned correctly.

The driveshaft on cars of the VAZ family is a fairly reliable unit. However, it also needs periodic maintenance. All driveline faults should be repaired as soon as possible. Otherwise, more serious and costly problems may arise.

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

We install the hinge and shaft in the following order:

We remove the cups from the new cross and insert it into the eyes.

Video: replacing the cardan cross on a VAZ 2101–07

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.
