Cars with front-wheel drive have a shaft with two grenades, through which torque is transmitted from the gearbox to the wheels. The mechanism tends to wear out, and it may be necessary to replace the outer CV joint on a VAZ 2114. The repair does not require special knowledge from the car owner who decided to service the car himself, and following the instructions for replacing the outer CV joint on a VAZ 2114 with your own hands, you can do it correctly.
This video clearly shows the process of replacing the internal grenade:
Symptoms of outer CV joint failure
Signs of mechanism failure are similar to an internal grenade:
- Crunch . While driving, turning the wheels and pressing hard on the gas, you will hear a distinct crunching sound in the front axle area. A common problem with outer CV joint failure is a torn boot during operation. If there is a suspicion of a malfunction, to diagnose it, just turn the wheel out and look behind it. When the rubber band covering the moving part breaks, dust and dirt begin to get into the mechanism. Because of this, the lubricant thickens and loses its properties, while acting as an abrasive and increasing production on the balls inside the part.
- Backlash . This also happens due to the development of the mechanism. In this case, vibration will be felt on the body when the car moves. To be sure of the problem, you need to grab the drive and swing it in different directions. If play is felt, it means the part is broken.
Remember that it is extremely unsafe to continue driving in such situations. You can damage your car by increasing the cost of repairs. It’s better to go to the nearest service center or call a tow truck.
VAZ 2114 grenade: signs of malfunction and diagnostics
So, the CV joint, which is actually a ball bearing, has races with transverse grooves to change the angle between the drive and driven axle shafts. It should be noted that on a car with front-wheel drive, it is the grenade that is the weak point for a number of reasons. Even taking into account the fact that all components of the part are made from materials of increased strength, signs of CV joint failure may appear as early as 50-60 thousand km. mileage
Failure occurs for various reasons, the most common being:
- damage to the CV joint boot and ingress of dirt and water;
- low quality or complete absence of CV joint lubrication;
- severe vehicle operating conditions, heavy loads;
At the same time, the main sign that the CV joint on a VAZ 2114, 2115 or other car needs to be replaced is the crunch of a grenade. This sound is made by balls rolling along ditches as wear and tear occurs.
By the way, there are two CV joints in the design (outer CV joint VAZ 2114 and inner CV joint VAZ 2114). Although both elements perform the same function, the external grenade fails much faster and more often. The reason is higher loads and rotation angles of the hinge in the hub area. So, signs and symptoms in the form of a crunch often point specifically to the external hinges.
In turn, the internal CV joint can make noise when driving in a straight line and manifests itself when overcoming bumps. Such a hinge will have play when tested. You can also hang the front wheels and engage 1st gear so that the wheels rotate in a suspended state. In this case, the inner CV joint becomes bent and a crunching sound appears from the faulty joint. All the signs discussed above indicate that the CV joint of 2114 or another car needs to be changed.
Necessary tool
If you decide to do the repairs yourself, you will need the following tools to disassemble the car:
- Open-end wrenches for 17, 19. But it is better to have a full set on hand;
- Set of heads and knobs;
- Wheelbrace and jack;
- Pliers;
- Screwdriver;
- Hammer;
- Rag and gloves.

Also make sure you have a complete replacement kit: grenade, boot, CV joint grease and two clamps. For convenience, you can drive onto a pit or overpass, and for safety reasons, set the car to the parking brake and put supports under the wheels.
The process of replacing the outer CV joint
Having prepared everything you need, you can figure out how to replace the outer CV joint. This is done according to the following points:
- Remove the decorative cover (if any) from the car disk and flare the hub bearing nut.
- We take a 30mm socket, a wrench and preferably an extension to provide greater leverage. We take off the nut.
- Jack up the car and remove the front wheel.
- For convenience, unscrew the brake caliper. This is done with a 17 key. The bolts are located on the back of the hub.
- We spread the pads with a screwdriver and remove the caliper along with the bracket securing it to the hub.
- To press out the steering tip, we need to unscrew the nut with a 19mm wrench, and then apply force to knock it up.
- We unscrew the two 17mm bolts that secure the ball joint.
- Now you can completely unscrew the hub nut.
- We pull the hub towards ourselves, removing the CV joint from it.
- Many car enthusiasts carry out the replacement process without removing the drive from the car. But if you are doing this in the garage, then for convenience it is better to remove it and move it to the workbench. If you have removed the drive from the box, plug the hole with a rag to prevent excess oil from leaking out.
- If the grenade boot is not torn, then use pliers to unclench the large clamp and, prying it up with a screwdriver, remove it.
- We carry out a similar process with a small clamp and move the cover down.
- We begin to knock down the old part with a hammer. Hit on different sides to remove the CV joint evenly.
- We clean the drive splines from grease to see the retaining rings.
- We replace the old ring with a new one, which comes with the grenade.
- We fill approximately 80 cm3 of lubricant into the CV joint cavity and install it on the drive. It is better to do this through a drift made of soft metals or through a block. This will help prevent damage to the new part.
- We install a new boot and place the clamps. Replacing the grenade boot is required in all cases of repair, even if the old one has slight wear. The fastener of each should be directed against the direction of the vehicle. Then we crimp them with pliers.
At this point, the repair process is completed and the entire chassis can be assembled in the reverse order.
Which grenades are better for the VAZ 2114: choosing the best option
Before considering the main topic of the article - which grenades are better for the VAZ 2114, you should first understand what this part is. A CV joint (otherwise called a grenade because of its characteristic shape) is an element of the front suspension of a car, extending from the hub of each wheel. It has an oblong shape with a thickening at the end. Its main purpose is to transmit torque at maximum rotation angles (reaching 70 degrees).
As for its service life, it can be noted that initially CV joints were created as elements with a very long service life (in some cases equal to the service life of the car itself). But, in practice, damage to the grenade occurs quite often, and the main reason for this is wear or cracks on the CV boot, allowing dust and dirt to get inside, violating the integrity of the structure and causing its damage.
Checking the damage to the grenade is quite simple - you just need to turn the car's wheels as far as possible in any direction and inspect the suspension. If the boots are damaged (that is, have cracks or tears), they should be replaced immediately. And in a situation where a grinding or other extraneous noise emanating from the suspension is heard while driving, conclusions can be drawn about the damage to the grenade and its failure.
In this case, it is categorically not recommended to continue driving - firstly, it is very dangerous and can lead to road accidents, and secondly, driving with a faulty CV joint can lead to the breakdown of a number of other parts and mechanisms, as a result of which the total cost of repairs is significantly will increase.
If the CV joint is damaged and noise is heard from the front suspension, it is absolutely forbidden to continue driving. This can not only lead to damage to other elements of the car, but is also very dangerous to life.
Cost of outer CV joint
If you are faced with the task of choosing a new part, it is best to choose a product from the manufacturer, that is, choose a genuine spare part. Most often, they have a price slightly higher than analogue ones, but are distinguished by excellent product quality.
But check the article number, as some auto stores may sell you a Chinese part with a box that is very similar to the original. The part should go under the number 21080-2215012-86. The price of the set will be about 1400 rubles .
If you want to purchase analog parts, then after reading the reviews, you can identify three quality companies:
- HOLA – 1200 rubles;
- GKN – 1600 rubles;
- KRAFT – 1150 rubles.
Before purchasing, it is best to study the reviews of the store where you want to purchase the part. This way you will be completely sure that you are buying a quality spare part. And in this article we presented prices for internal grenades of the VAZ 2114 from 10 manufacturers.
What brand of grenade should I choose and what boots should I install?
Almost all motorists who are faced with a breakdown of this element are wondering - which CV joint is better for a VAZ 2114 - domestic or imported? The answer to this question can be completely unambiguous - the best CV joints are the original ones, produced by AvtoVAZ itself.
The only difficulty that exists here is that such grenades have not been and are not on sale, so it is very difficult to get them.
You can either try to look for them at auto repair shops (however, here you can unknowingly buy used ones, which is not very good - after all, the part may already be damaged) or go to an official AvtoVAZ service center (but the price will be very high). For these reasons, it would be best to look at products from other manufacturers.
So, the answer to the question which outer CV joint for the VAZ 2114 is better can be any of the following companies:
The first three companies on this list are especially popular among domestic car enthusiasts, so if there is a choice in a car store, it would be better to give preference to them. Also, when buying new grenades, you should not forget about buying new boots (mounting new CV joints with old, albeit “working” boots, would be a very big mistake).
It’s not worth talking in detail about which CV joint boots are best for the VAZ 2114. All anthers can currently be divided into two types - ordinary, almost no different from the anthers installed at the factory, and the so-called “reinforced”.
When buying the latter, it is worth remembering that along with them you should also buy mounting clamps of an increased size, since clamps from ordinary boots will not fit. All of these anthers have approximately the same quality, regardless of the manufacturer (some believe that silicone anthers last a little longer, but, as practice and reviews from many motorists show, the difference between silicone anthers and conventional ones in terms of service life is minimal).
The most important thing to do when buying anther is to check its quality. It must not have cracks, tears or other damage. The CV joint boots should be replaced with new ones at the first signs of wear.
Cost of replacement at a car service center
If you do not want to do the repairs yourself, you can contact a car service in your city. Prices for repair work can range from 800 to 1,500 rubles, if we consider the average prices in Russia.
If you are limited in finances and want to save almost half of the repair budget, changing the external CV joint on a VAZ 2114 yourself is not so difficult. But in any case, approach the choice of spare parts carefully, since if you buy a part that is obviously not of high quality, you may again encounter the problem of a worn grenade in the near future. Try to check the condition of the anthers at least once a month, this will help extend the life of the mechanism. You will have time to replace the outer CV joint boot in time and the mechanism will not have time to become dirty. Well, if the connection is severely worn out and begins to make extraneous sounds, it is better to begin repairs immediately, otherwise you may create a threat to other road users.
Let's sum it up
Taking into account the design of the CV joint and its purpose, it becomes clear that the grenade boot plays a vital role. This seemingly simple element protects the CV joint from water and dirt. In turn, damage to the integrity or slipping of the boot will cause the sand to act like an abrasive, and water will lead to corrosion, leaching of lubricant, etc.
The result is crunching, rapid wear and the need for premature replacement of the outer or inner grenade. Of course, in order for this element to serve as long as possible, the condition of the grenade anthers must be monitored at every maintenance. Even the slightest defects in the form of cracks, breaks, deformation, etc. are not allowed.
As a final note, we note that it is better to select a CV joint from a well-known brand and manufacturer. In other words, it is better to take a more expensive part than a cheap analogue from little-known manufacturers. In practice, there have been cases when a new and absolutely correctly installed CV joint did not last even 20 thousand km. The reason is the low quality of the part, cheap materials that are not wear-resistant.
To avoid such problems, it is recommended to purchase original spare parts (CV joints for VAZ) or analogues that are not inferior or even superior to the original in quality. At the same time, it is better to immediately refuse to buy cheaper options, since not only comfort, but also safety when driving a car directly depends on the reliability of CV joints.
