The CV joint is a constant velocity joint. People simply call it a grenade. This is due to the appearance of the device. Its task is to transmit rotational motion from one axle shaft to another, and they are at a constantly changing angle in relation to one another.
This element is always under load, which is why its failure is rather a matter of time. This is even despite the fact that high-quality carbon steel is used in the production of CV joints, which can withstand severe regular loads over a long period of time.
But the grenade on the VAZ 2110 still fails. The main reasons are pollution, sand that gets inside the structure, loss of lubrication, damage to elements, torn rubber boots.
Kinds
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
- The first grenade is internal, and it transmits torque to the shaft from the transmission.
- 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.
How to diagnose a problem
It is clear that there are no problems diagnosing obvious faults. But what to do if there are no visible faults, the machine is working normally, although in fact minor, insignificant damage that can lead to expensive repairs has already appeared? There are two main effective methods for determining a malfunction:
- Listen to the car while driving. If you think you have heard unusual noises, do the following: stop, move the gearshift lever into first or forward gear (depending on the type of transmission), then turn the steering wheel as far as possible in either direction. Next, take off sharply, pressing the gas pedal fully. If during such a maneuver you hear crackling or clicking sounds from the front of the car, check the condition of the CV joints.
- Options for visual diagnosis of faults include a careful external inspection of the condition of the anthers. If, when looking at the wheel rims (this will be especially noticeable on alloy wheels, since stamped ones make it difficult to see), you see traces of thick grease on the front ones, it means that the boot is torn and urgent intervention is required. If there are no traces of lubricant on the discs, then carefully inspect the boot itself. Any defects on it mean the possibility of dust, dirt and water getting inside the hinge. Therefore, make sure that there are no scratches or cracks on the boot itself, as well as that the clamps are securely tightened (the most common cause of contamination and lubricant leakage from the boot).
"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.
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.

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.
But to understand whether an element really needs to be replaced, do this:
- Raise the drive wheels, which will allow you to bring the inner CV joint to its maximum angle;
- Start the engine;
- Turn on first speed;
- If the hinge is at the limit of wear, you will hear a characteristic crunch. This is a signal that you need to change the grenade.
Which CV joint boot is better to install on VAZ 2110-2109, 2110
First of all, the outer boot must be suitable in size if we are not buying an original one, but an analogue. The dimensions of the VAZ boot are as follows:
It is also important to pay attention to the material from which the boot is made. Silicone work well , they are easy to distinguish by their softness, they are often made of unpainted silicone, translucent.
Types of anthers on CV joints and their main weak points
Polyurethane anthers on VAZ are a rather controversial thing. On the one hand, polyurethane is a durable and tear-resistant material. On the other hand, in severe frost they can harden so much that there is a risk of rupture right on the move. It all depends on the composition of the polymer.
rubber boots is also ambiguous, since rubber is different from rubber. If we choose this option, it is better to start with a brand that we trust. And a little about brands.
NTN-SNR, France
Definitely recommended for purchase. Made of polyester (PEEST marking), it has an interesting design feature - fillets are made between the corrugations to remove the load from a specific corrugation and distribute it evenly over the entire surface. The catalog number is the same as that of the branded VAZ boot - 2108-2215030. The resource is more than 150 thousand km , it is not afraid of frost and high temperatures.
HORS, RF
Sold in branded packaging, made of red-painted silicone. The packaging indicates a 1-year warranty; it responds well to severe frosts, but the total resource does not exceed 8-10 thousand km , depending on operating conditions. 2108-2215036 is indicated on the case body .
TRACK, country of origin unknown
Made of transparent silicone, packaged in a blister with a sticker stating a one-year or 40 thousand km warranty. It is absolutely not afraid of frost, it will last more than 50,000 km , if it is not a fake. The specified catalog number is 2110-2215030.
BRT, RF
Made of black material, chloroprene rubber. Indifferent to frost, service life at least 40,000 km . Sold without packaging, all information is embossed on the case, catalog number 2110-2215030 .
Trialli RG 0130, Russian Federation
Made of black chloroprene rubber, packaged in a bag with a sticker, logo and factory catalog number 2108-2215030. Judging by the reviews, it has performed well, is not inclined to become dull in the cold, users estimate the average resource to be within 30-40 thousand km .
TSN 3.2.1, China
It makes no sense for replacement, since the resource under normal conditions is no more than 2,000 km. True, it is sold complete with good clamps and lubricant for the CV joint. Marked with serial number 2108-2215030.
There are also a number of domestic and Chinese anthers that correspond to the factory catalog numbers, but you can buy them at your own peril and risk if you do not trust the VAZ cover.
Replacement procedure
Let's say right away that it is impossible to repair the CV joint. So don't even try. The most correct and reasonable decision is to purchase a new grenade and install it in place of the failed one.
The first thing we recommend starting with is watching a video about replacing the CV joint on a VAZ 2110. This way you will clearly understand how the procedure is performed and in what sequence. Then, according to the instructions we have presented, you can get to work.
- Since the CV joint is located at the bottom of the car, you will need a lift or a pit in the garage from where you can begin replacing the element.
- Be sure to secure the car. To do this, you can engage fourth gear and tighten the handbrake all the way.
- If you have driven the car into a pit, place wedges or wooden blocks under the wheels to block the wheels.
- Remove the protective cap and unscrew the nut on the hub.
- After removing the hub nut, unscrew the wheel fasteners.
- Raise the wheel that requires CV joint replacement using a jack.
- Now unscrew each of the six bolts of the part, after which only the flange will hold it.
- Remove two bolts from the lower knuckle support.
- Turn the steering wheel all the way, which will allow the element to fall out on its own.
- Remove the boot, which is located in the grenade structure.
- Remove the retaining ring.
- Unscrew the hinge from the shaft spline to avoid damaging other components.
- Check the operation of the entire system to determine the causes of the breakdown.
- Install a new CV joint using the steps in reverse order.
Assembly nuances
Before reassembling, we also recommend watching a video about replacing the inner CV joint on a VAZ 2110. Plus, follow a few tips.
- A plastic plug must be installed at the end of the shaft.
- Before installing a new CV joint, the element must be lubricated with special compounds.
- You need to install the retaining ring before installing the new unit - the grenade.
- Having installed the drive, it is mounted on the gear, achieving complete fixation. At this point you will need to use a hammer.
You can see for yourself that replacing a grenade does not pose any special difficulties. However, unless you have absolutely no experience repairing your car yourself, doing the work yourself is highly not recommended.
The best solution would be to find a good service station, where real professionals work. Trust them to replace grenades to guarantee high quality repairs and efficient operation of the entire chassis of your car.
Well, if this is not the first time you are repairing your “ten”, then such a procedure as replacing a CV joint will become an easily feasible task for you. Just remember to follow the recommendations from the instruction manual for your VAZ 2110.
The CV boot is a special element designed to protect constant velocity joints from the effects of dirt dust and various external factors. It is made of rubber and is mounted on the outer and inner CV joints, thereby holding all the lubricant inside, which is necessary for operation.
The video shows the process of replacing the CV joint boot on front-wheel drive cars of the VAZ family.
