Replacing the outer CV joint boot of a VAZ 2110 without any particular difficulties can be done with your own hands in literally half an hour. You will need a new CV boot, a tube of lubricant, a couple of new clamps, a screwdriver, several wrenches to pull the CV joint out of the steering knuckle and a hammer to knock it off the drive. To see the procedure for replacing the CV joint boot on VAZ 2110, 2111, 2112 or other front-wheel drive vehicles, watch the video.

And so, in order to free the drive shaft, and then remove the outer CV joint and pull off its boot, you will have to disconnect the steering tip, unscrew the hub nut, and unscrew the 2 bolts securing the ball joint. After dismantling the grenade, be sure to wash out the old lubricant and thoroughly fill it with new one!

Grenade boot and its replacement

The grenade of the VAZ 2110 car is a constant velocity joint that forces the front drive wheels to rotate and allows them to turn. The peculiarity of this device is that it is capable of transmitting rotational movements to axle shafts located in relation to each other at a constantly changing angle. Replacing the boot of a VAZ 2110 grenade is necessary when noise and knocking are heard, especially when driving on sand. You can easily replace the boot of a VAZ 2110 grenade with your own hands, fortunately there are step-by-step instructions.

Constant velocity joint or CV joint

The design of the car provides that the hinge is subject to a significant load and is made of very strong alloys. A well-maintained and good CV joint (grenade) can last longer than the car itself. To achieve this result and save money, because the procedure for replacing a hinge is expensive, you must follow some rules. One of these rules is to systematically check the condition and timely replacement of the grenade boot. The most important enemies of a car grenade are dirt, dust, water and sand that enter the working part while driving. To protect against such destructive factors, anthers are installed, which are protective rubber cones that very tightly cover the CV joint mechanism of the vase. If you find that the grenade boot is torn, it must be replaced immediately. During periodic technical inspections, you need to carefully inspect the boots and replace them if necessary.

Note. If folds, cracks, deterioration in the elasticity of the rubber and other deformations and damage are found on the anthers, replacement should not be shelved.

Assembly of the unit

The assembly process for the outer CV joint is as follows:

• We stretch a new rubber element onto the shaft;
• We place a washed or new CV joint on the shaft splines (if it is also being changed), and then we stuff it so that the groove in the joint cage fits onto the locking ring, which will ensure fixation from removal;
• We add new lubricant (press it into the hinge itself, as well as into the boot);
• We pull the boot onto the outer casing;
• Use your hand to press the boot a little to squeeze out the air from inside;
• We put on the clamps and fix everything.

After this, the drive is installed back - the hub is put on the splines of the limit switch and the whole thing is secured with a nut. Next, put the rod end, support and wheel in place.

After removing the car from the jack, tighten the drive fastening nut and using a powerful screwdriver, it is cored (its skirt is bent into the groove on the shaft) to prevent spontaneous loosening.

Replacing the CV boot

The process of replacing the boot is not as complicated as it seems at first glance. Most car owners change the boots one at a time, that is, when the inner boot wears out, the grenades change it without touching the outer one. And after a while, after damage or wear of the outer boot, they change it. This is a pointless waste of money, effort and time.

Note. It is strongly recommended that if it is necessary to service and repair CV joints, remove the entire shaft and replace both the inner and outer boots at the same time.

Functionality check

of the inner and outer CV joints should be examined separately , since the procedures and signs are somewhat different.

External grenade

The most obvious and main sign of wear of this element is the appearance of a sound similar to a crunch. It appears because the grooves have worn out and the balls do not move along them as well as before. The crunching becomes noticeable when entering turns, sharply pressing the gas pedal or passing difficult road sections.

Grenade

If you want to verify that the outer CV joint is faulty, do the following:

• When starting from a standstill, deliberately create jerks, but not strong ones;
• Try to accelerate sharply and slow down;
• Move the shaft transversely between the CV joints. If you feel any play, then the grenade is definitely worn out.

Internal grenade

It is noteworthy that the internal hinge is more durable and less subject to wear. Most often, the inner CV joint declares its malfunction when simply driving in a straight line or when passing through difficult sections. A check for play, similar to an external grenade, will allow you to verify problems.

Purpose and principle of operation, possible malfunctions

The constant velocity joint of the VAZ 2110 car model (abbreviated CV joint) is subject to loads throughout the entire period of operation, which leads to its failure. The design is distinguished by the highest level of properties; high-quality carbon steel is used for its production, capable of withstanding loads for a long period of time.

CV joint VAZ 2110

The reasons for the failure of the CV joint VAZ 2110 vehicle include the ingress of various parts of dirt and sand inside, which is associated with loss of lubrication and at some point leads to damage if the equipment is operated with a torn rubber boot. In this case, it will be necessary to urgently replace the internal grenade, which fails and needs to be monitored for technical condition, guaranteeing long-term operation of the VAZ 2110 model car. You can find the need to replace the internal CV joint of the VAZ 2110 if you hear a corresponding crunch caused by the presence of gaps in the mechanism, foreign bodies leading to malfunction.

Drive design features

The main advantage of CV joints, in comparison with conventional joints, is the transmission of rotation without loss, even with a strong change in the angle between the components of the shaft (up to 70 degrees).

In total, the VAZ-2108 drive shaft includes three components:

1. Shaft (with connecting splines);
2. Internal CV joint (for interaction with the box);
3. The hinge is external (provides interaction with the wheel hub).

Both hinges used on the VAZ-2108 are of the ball type; they are almost identical in design, but differ in size. Thus, the outer ring of the internal element has a significantly greater depth. This provides the possibility of axial displacement of the inner race, and as a result, a change in the length of the shaft, which is necessary for the drive wheels to make turns. In addition, the left and right drive shaft assemblies are different lengths.

The main components of the CV joint are:

• Outer ring (made in the form of a glass, special grooves are made on the inner surface);
• Inner race (represents a power fist, which also has grooves);
• Balloons;
• Separator (prevents balls from falling out);

All this is assembled into a single structure, so it is generally impossible to check the VAZ-2108 CV joint, even if it is completely disassembled.

The inner races are connected to the shaft using splines. They are secured against removal with locking rings.

The outer races are made integral with the limit switches, which are splined into the gearbox and hub. But the end stop of the inner CV joint is secured in the box with a retaining ring, but the outer joint is secured with a threaded connection (nut).

What will you need at work?

When replacing the internal CV joint of a VAZ 2110 car, you need to select the right equipment and tools, without which the next job is impossible. Repairing the unit does not seem likely; it will only need to be replaced .

To perform the following operations, you will need a set of equipment and tools:

• A new internal grenade, which includes a clamp and lubricant, will ensure subsequent trouble-free operation of the system over a long period of time;
• A lift, or a special inspection hole with a jack, will be required to lift and secure vehicle , guaranteeing safety during the work;
• A set of standard tools used to replace the internal CV joint. Includes wrenches, screwdrivers, pliers and much more needed for repairs.

"Grenade" defects

Before replacing CV joints on a VAZ 2110, you need to make sure that they are made with high quality and can effectively perform their job in a new place.

Alas, sometimes replacing the inner CV joint on a VAZ 2110 does not give the expected result, since product defects .

The literature indicates that CV joints are made from special high-strength alloys that practically do not wear out. But in practice everything looks a little different. Whatever one may say, there are no eternal parts, and CV joints are no exception.

Defects may be as follows:

• Low quality of alloys used in manufacturing;
• Banal fakes and defective components;
• Poor quality or complete lack of lubricant, which leads to rapid failure of even a new grenade;
• Damaged anthers, due to which all kinds of debris get into the grenade.

Regarding the replacement of CV joint boots on a VAZ 2110, we recommend watching a video that will help you cope with the problem that has arisen. This issue should be approached thoroughly.

Replacement of failed equipment

Replacing the CV joint of a VAZ 2110 vehicle, located on the inside rather than the outside, is a simple process; several operations will be required. The design transmits rotation from the gearbox to the shaft. The operation of the device affects traffic safety; for this reason, detection of a CV joint failure is carried out at a high level from the ground.

The replacement operation is performed on a special lift, an inspection hole, which is due to its location in the lower part of the vehicle; access is needed only in this position.

Design

Drive diagram
If you disassemble the CV joint, it will consist of three main elements:

• Inner ring;
• A ring with holes that hold six balls - a separator;
• The hinge body together with the drive shaft.

In a VAZ 2110 car, the CV joint may need to be replaced. But which one exactly? After all, in the “ten” there are two of them - internal and external. They are necessary in order to effectively overcome all obstacles. Here one CV joint will clearly not be enough.

Internal and external

1. The first grenade is internal, and it transmits torque to the shaft from the transmission.
2. The second grenade is external and engages with the car's wheel hub.

Despite the fact that their operating principle is the same, they differ in design and price.

We change a grenade on a VAZ 2110 without removing the drive

This is the first, shortest path, which implies the presence of all the specified tools. Everything is quite simple.

• Before jacking up the car, you need to unscrew the grenade nut. To do this, we seat the assistant in the cabin; he must press the brake pedal with all his might and hold the steering wheel. In order to unscrew a grenade after a conscientious tightening, you need a lever of about a meter, sometimes more. The threads are usual everywhere, right-handed.
• Then we remove the wheel bolts, jack it up and remove the wheel.
• We unscrew the two 17mm bolts that hold the ball joint, disengage the splines, and move the hub to the side.
• Now, using a tool for removing clamps or a screwdriver, depending on the type of clamp, remove it. Don't forget about the small clamp.
• Now we screw the reverse hammer with a welded nut onto the grenade. We clamp the drive with a gas key so that it rests against the forged lever (saber). This is necessary in order not to tear the drive out of the box, otherwise you will have to take the second path. With a sharp blow we rip the grenade off the slots.
• We remove the boot; as a rule, the grenade fails precisely because it has broken through.

Important! Under no circumstances should you install the anthers that come with the grenade. They are made of very low-quality rubber, become tanned at the slightest cold snap and burst. Therefore, you will soon have to change the grenade again.

• We install a new boot. We do this very carefully, preferably after washing the slots first. The main problem is the thrust ring; carefully throw the boot over it with a screwdriver.
• Now we tighten the inner clamp, screw the new grenade onto the hammer, and then hammer it into place. Theoretically, this can be done with a hammer through an old nut; knocking a grenade down with a hammer is also possible, but there is a risk of damaging the slots if you are not used to it.
• We take CV joint lubricant, it is usually included in the kit. We squeeze it out in a circle onto the balls, removing the boot and turning the grenade inside out.
• Next, tighten the clamp.
• We put everything back together in reverse order.
• It is very important to tighten the nut just as tightly and be sure to tighten it.
