Initially, CV joints were positioned as elements with a very long service life. Manufacturers even assured that they could last as long as the car itself.

But in reality, everything is not as colorful as it is described. A grenade has a life limit. What grenades, you ask. The grenade is the CV joint. People often use the concept of “grenade”. This can be explained very simply - the CV joint looks like a grenade. That's all. Therefore, do not be confused if you hear “grenade” when talking about CV joints. It is the same.

Location

It will be impossible to replace the CV joint on a VAZ 2114 if you do not know where exactly these elements are located. Their location is easy to determine - on both sides of the front suspension at the bottom of the car. They are oblong elements and fit into the hub of each wheel.

That is, getting to the node is not difficult, but this will require certain conditions.

The most important thing is that the replacement procedure is not complicated, which allows you to do the work yourself. But let’s say right away that if you don’t have the time, desire, or are simply not confident in your own skills, it’s better to entrust the repair to specialists. You will spend extra money on this, but you will be sure of the result.

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.

When replacement is required

If while driving your car you hear noise coming from the front of the car, be sure to check the condition of the boot. Quite often, replacing the outer CV joint boot of a VAZ 2114 becomes a daily task for service center employees.

To check, just turn the wheels in any direction and look under it. If cracks or complete damage are detected on the boot, the outer CV joint of the VAZ 2114 will definitely need to be replaced.

The presence of damage indicates that dirt has gotten inside the element. Much or little of it is no longer so important. Contamination leads to disruption of the functionality of the device.

In such situations, when the CV joint is damaged, it is strongly not recommended to continue driving under your own power. This is dangerous for you, your car and other road users. Ignoring this recommendation entails even more expensive repairs, since by the time you get to the garage or car service center, you will damage a number of other components and elements of the car.

Why change

If damaged anthers are found, they must be replaced. Otherwise, dirt will penetrate into the “grenade” through cracks and tears and over time the part will fail, and there will be a need to purchase a new element and then replace it.

What do you mean it will fail? When the car moves at any turn, the CV joint will fall apart into two parts. It will be impossible to continue operating such a machine. In addition, all the oil may leak out of the box.

To avoid unpleasant consequences, it is necessary to promptly replace the damaged part.

An outer CV joint will cost 1000 - 1500 rubles, depending on the manufacturer. The price of the internal “grenade” is slightly higher than 1400 – 2200 rubles.

What to choose?

To replace the inner or outer CV joint on a VAZ 2114, a new element will be required. To be fair, we note that the most suitable and high-quality CV joints for the VAZ 2114 model are produced by the manufacturer, that is, AvtoVAZ.

But here comes the most important disappointment - they are not for sale. The only option is to go to a specialized VAZ official car service center. But from the point of view of financial costs, it is not the most reasonable decision.

In addition, there is now a fairly wide range of analogues on the market. Judging by the reviews of VAZ 2114 owners, special attention should be paid to CV joints produced by such companies as:

• Hola;
• GKN;
• Kraft.

Signs of failure of the outer grenade (CV joint).

There are two options here:

• signs that your grenade has already broken
• signs that the grenade will soon come out and break .

How to understand that a grenade will soon break.

Of course, the first sign of a malfunction of the external grenade is a crackling sound . If you hear a crackling noise while driving with the steering wheel turned, it is definitely a CV joint. The greater the angle of rotation of the wheel and the harder you press on the gas, the louder the clicks. Another sign that does not always appear is vibration on the steering wheel at speeds greater than 80 km/h. The vibration is only slightly similar to the vibration from an unbalanced wheel. It usually manifests itself as a slight twitching of the steering wheel.

How to understand that the outer CV joint has broken.

If the CV joint breaks, the car will stop moving. In any gear engaged, press the gas, the speed increases, but the car does not move.

How to understand that it is the outer CV joint that has broken, and not the internal one or the clutch in general (the first signs of failure are similar to the signs of a clutch failure)? First of all, start the car and put it in any gear. Next, open the hood and look in turn at each of the shafts going from the box to the wheels (one short, the other long). If any shaft is spinning, it means that the CV joint has broken on this side.

I recommend not just visually looking at the shaft, but touching it with some long, hard object, such as a stick. The main thing is that there is nothing on it that can wrap around the shaft !!! When you touch the shaft with a stick, if it is spinning, you will feel a slight vibration. This is usually done in the dark, because it is difficult to understand whether a cylindrical object is spinning, especially in the dark.

Replacement

Armed with new CV joints, also collect a set of necessary tools and materials. It will include:

• Set of heads;
• Spanners;
• Shoes;
• Dry rags;
• Grease for CV joints;
• Jack;
• Anthers.

Now let's get down to work on replacing the CV joints:

1. Determine the location where the repairs will be carried out. This could be an overpass, a garage with an inspection hole, or a room with a car lift.
2. Stop the engine and apply the handbrake. Use chocks to block the wheels.
3. Using a wheel wrench, remove the wheel bolts.
4. Raise the required part of the car with a jack.
5. Loosen the nut in the center of the CV joint. Keep an eye on the puck so you don't lose it. It is not included with the new CV joint.
6. Armed with 13mm wrenches, unscrew the fasteners of the upper part of the ball joint. It is not necessary to perform a similar procedure with the lower part, since it will not interfere with the repair process.
7. Using a pry bar, slightly rip the grooves off the support and move them aside.
8. Knock the hub off the CV joint splines. To do this you will need a hammer and some kind of wooden stand.
9. Remove the old damaged CV joint.
10. Check for damage to the stem.
11. Remove any remaining lubricant from the rod using a dry rag.
12. Place a new grenade in the new location. This assembly should include a CV joint, boot, clamps, nuts, and retaining rings.
13. When assembling the unit, do not forget to use high-quality lubricants. There shouldn’t be too much of it, but you shouldn’t feel too sorry either.
14. Reassemble the parts in reverse order.
15. By changing the CV joints, you can simultaneously check the condition of the brake pads. If they are in a sufficiently worn condition, it is advised to replace them at the same time. Anyway, you have already dismantled the knot.
16. After completing the repair, check the car in action.
17. It’s not uncommon for craftsmen without much experience to leave behind supposedly unnecessary parts after reassembly. Please note that everything that remains after assembly, and that is not the released elements that you replaced with new ones, has its place in the design of the car. Therefore, check where exactly these “extra” elements come from and install them in their rightful place.

How to install a new CV joint on a VAZ.

Be sure to follow this sequence for installing new parts:

1. Small clamp.
2. Grenade boot.
3. Large clamp.
4. Retaining ring.
5. The CV joint itself.

First, we clean the drive shaft from dust, dirt and old grease. Most CV joints come with lubricant, a boot, two clamps and sometimes a new hub nut. If suddenly there is no lubricant in the kit, it is better to use graphite lubricant, and if it is not available, then simple lithol. First of all, we put on a small collar. Then the boot (it should go behind the limiting washer) and a large clamp. Then we put a retaining ring on the drive shaft. Now open the tube of lubricant and completely squeeze it into the grenade. Now it's time to put the CV joint on the drive. Because of the locking ring, it will be difficult to insert the drive into the grenade, so we take a hammer and lightly, trying not to damage the thread, press the grenade into place. Now you need to put the boot on the CV joint and tighten the clamps. Assembly occurs in reverse disassembly sequence, but there is one nuance! Do not overtighten the hub nut! This may cause the bearing to hum. The hub nut must be tightened with a force of 225.0–250.0 N*m. Of course, few people have a torque wrench. So, tighten the nut tightly, but not with all your might. In theory, a force of a maximum of 25 kg will need to be applied to a meter-long knob. But, the extension pipe will spring back under such force, so how can you describe it exactly? But obviously there is no need to jump with weight.

I hope I helped you. If you have any questions, ask them in the comments.

Replacing the boot of the outer CV joint of a VAZ 2114, internal or external grenade

To change the CV joint, you need to prepare a workplace and tools. First of all, you will need a garage with a pit, jacks, and supports. You also need to have wrenches “17”, “19” and “12”, as well as a wrench for “30”. You also need to prepare a puller for pressing out the steering tip, a rope or wire, CV joint grease-4 or suitable analogues, a hammer and pliers.

• We put the car on the handbrake, install wheel chocks under the wheels, and remove the front wheels;
• then the front wheel bearing nut is unscrewed and the car is raised on a jack;
• you can put the wheel under the car and lower it from the jack;
• then, using the “17” key, unscrew the two brake caliper mounting bolts, one at the top and bottom;
• now you need to spread the brake pads with a screwdriver;
• then remove the brake caliper assembly with brake pads and mounting bracket;
• then the brake caliper must be tied with wire or rope so that the structure does not sag on the brake hose;
• now, using the “19” key, unscrew the steering tip nut;
• Having unscrewed the nut, you need to install a puller to press the steering tip out of the swing arm and press the tip out;
• then, using the “17” key, unscrew a pair of ball joint bolts;
• Next you need to unscrew the hub bearing nut and remove the washer;
• Now you can unscrew the fastening of the ball joint to the steering knuckle, then remove the CV joint from the bearing hole and then with a strong jerk remove the shaft with grenades (if you can’t remove it manually, you need to gently press it with a screwdriver);
• Please note that if the gearbox oil has not been drained, the hole must be plugged with a clean rag to prevent it from leaking out;
• Next, using pliers, you should grab and unclench the large clamp, pry it off with a screwdriver and disconnect it;
• then the remnants of the boot are removed from the CV joint, after which the smaller clamp is opened in the same way, and the cover is moved along the shaft;
• at this stage, use a hammer to knock out the old CV joint from the drive shaft of the wheels, wipe off the lubricant with a clean rag;

The importance of CV joints

The internal hinge is larger than its brother, and therefore more expensive, since it plays a more important role. It transmits rotation to the shaft from the gear. It is also installed inside the gearbox housing. The maximum rotation angle of the internal grenade is 20 degrees.

The outer hinge serves to rotate the wheel hub, and therefore it has mounting splines. The external grenade does not have much free space, so it is inferior in size. Installed next to the wheel.

Which brand of grenade should I choose?

When searching for components, you should approach their selection with care. The CV joint is the main part of the car's drive and often fails, so you should choose a spare part not only for reasons of price, but also quality.

It’s better to find the original; look carefully at the box in which the CV joint is sold, as you can often find a very high-quality fake. Also pay attention to the part number, it should be 2108-2215056 . The average price is about 2000 rubles .

When considering certified analog spare parts for purchase, you should look at the quality of workmanship. Even reading most of the positive reviews about a particular brand, you should not exclude the percentage of defects, which always exists.
