How to remove the inner CV joint on a Niva - step-by-step instructions

Since the front suspension and drive axle of the Niva 2121 are designed similarly to the front-wheel drive family of the concern, it will not be possible to avoid damage to the CV joints. An expiring resource is indicated by:

• a characteristic crunch when driving with the wheels turned out;
• jerks during acceleration;
• increased vibration while driving;
• tapping when overcoming bumps.

Since each side has two “grenades”: internal and external, diagnosing the problem for each part has its own characteristics.

So, to expose the outer CV joint, it is necessary to put the maximum load on it, turning the wheels alternately in each direction and applying gas; for the inner one, you should find a straight, obviously uneven section of the road.

Depending on the degree of wear, the intensity of sounds and other manifestations will vary.

As a rule, the element can withstand a damaged condition for a long time. However, in this case, no one can give a guarantee when the “grenade” itself or the bearing falls apart. The total resource is often equal to the total mileage of the car for the entire period of use, but in most cases it is rented out at 120-130 thousand km.

Which to choose

Depending on the year of manufacture, the Niva 2121 can be equipped with CV joints with 22 or 24 splines. Before 2002, the first version was distributed, after 2002 – the second. According to another version, 22-spline “grenades” were common until 2007.

The surest way to determine the type is to remove the hub washer and count by hand.

Operating experience shows that the best quality grenades for the Niva are produced by AvtoVAZ; also, if you are confident in the origin of the product, it makes sense to pay attention to the products of CORAM and Pilenga.

Recommendations for choosing CV joints on Niva

The first thing you should pay attention to is the number of teeth (splines) on the hinge. Until 2004, there were 22 of them (the hub corresponded to this number), then there were 24, but sometimes units with 22 were still installed. So you just need to count them on your machine. But if everything is clear with this point, another question arises - about the manufacturer. Most experienced Niva owners recommend purchasing factory hinges, complete with shafts. The only negative here is the huge number of counterfeit products. There are only three main large suppliers: VAZ, BelMag, Trialli. Another company, LGR, overcomes the 5% sales barrier.

Alternative manufacturers:

• Pilenga;
• STK;
• Hofer;
• Baker;
• G.K.N.

Removing the drive

The operation of dismantling the drive elements is possible if you have:

• jack;
• block of wood;
• wheel wrench;
• keys for 13, 17 and 23 (the first two varieties in double quantity);
• slotted screwdrivers;
• punch;
• a device for removing factory-made clamps or made from adjustable pliers;
• anthers;
• clamps;
• hub nut;
• CV joint grease-4M;
• a rag for wiping off grease;
• kerosene.

With the car slightly jacked up, the cap covering the hub is removed, the hub is completely unscrewed and the wheel nuts are loosened.

The wheel is hung up and dismantled.

The lower lever smoothly lowers onto a strong block.

The nuts holding the ball joint are removed (3 pieces). The outer CV joint shaft is carefully removed from the steering knuckle by pulling the latter back and up.

The steering knuckle is secured with a wire to a suitable protrusion. The lower shock absorber mount is released from the lever, after which it is necessary to raise the jack a few more centimeters up.

Using pliers and a screwdriver, it is necessary to remove the inner CV joint boot clamps, as well as the boot itself. Then the retaining ring located inside the “grenade” body is removed, and the structure is removed from the car.

The main symptoms of CV joint failure on Niva

The first sign is the appearance of a characteristic crunching sound from one, or less often both, wheels while driving. An unpleasant sound appears when turning and when accelerating. The crunch is heard especially clearly during a sharp start. And another symptom is jerking during acceleration. Having realized that replacing the CV joint on the Niva is needed in the very near future, it is necessary to determine what exactly has failed.

You can do this in two ways:

1. On a stationary car. You will need to move your hands, tug the shaft connecting the hinges - there should be no play. Its presence indicates the need to replace the unit. To check the inner CV joint, hang one of the wheels and turn on first gear - the faulty unit will certainly crunch when the wheel rotates.
2. When moving. You need to drive on a flat road, alternately turning the steering wheel in one direction or the other. A crunching sound will be heard from the side where the outer unit is faulty. To check the internal joints, you will need to overcome small holes and bumps at low speed so that the wheel drops as low as possible. Where the crunching sound comes from is where the internal CV joint on the Niva needs to be replaced.

It should be noted: a crunch in the hinges indicates that replacing the Niva 2121 internal or external CV joint is inevitable. The hinge can still be saved if you notice it in time.

Primary signs include:

• boot rupture;
• the appearance of grease on the inner surface of the wheel due to a torn boot;
• a whistling sound reminiscent of friction against metal;
• weak jerks when moving away (the grooves of the “grenade” begin to break), sometimes weak clicks (2-5).

Disassembly and maintenance of the inner CV joint

When the internal “grenade” is in your hands, you should collect the fallen bearings and place all the elements in a bath with kerosene, rinse thoroughly to remove dirt and old grease.

The shaft is freed from the retaining ring that holds the inner race of the hinge, as well as the race and separator.

Using a puller or modified pliers, the thrust ring is pulled off.

Tools that may be required for replacement

In order to remove the inner CV joint on a Niva yourself for the purpose of subsequent replacement, you may need tools such as:

• Driver and ratchet.
• Head 13.27 mm.
• Hammer.
• Extension.
• Jack.
• Flat screwdriver, chisel.
• Balloon wrench.

Many people prefer to change the CV joint themselves to save money. But it is worth noting that auto mechanics are not born, not every person can do this, that is, not all people know how to remove the internal CV joint on a Niva. Therefore, in this case, it is best to seek help from specialists. But it is worth noting that replacing this element is a rather expensive procedure.

Disassembly and maintenance of the outer CV joint

By carefully using a drift and a hammer on the end of the cage, the hinge is knocked off.

Next, the retaining ring is removed from the shaft.

And a stubborn ring.

All elements are washed in kerosene and cleaned with an iron brush.

Structure

Important! If you decide to replace the CV joint yourself completely or change its individual parts, you need to understand its design, and only then dismantle it and then replace it.

Replacing a CV joint is an expensive procedure, which in a service center will significantly affect the thickness of the car owner’s wallet. The part is made of heavy-duty materials that are resistant to mechanical stress and aggressive environments. Accordingly, these materials, like the part itself, are quite expensive. It is designed for long-term operation, but not always road conditions and the driving style of the drivers themselves allow all parts of the chassis to be used for many years without the slightest breakdown.

And the cost of replacing a CV joint will be approximately half the cost of the mechanism. That is why many try to replace it themselves in order to save some money on repairs. But not everyone is born an auto mechanic, so the average person must first find out what parts the mechanism consists of. Here is their list:

The anthers perform two functions at once: they protect the hinge from dust and dirt. After all, in essence, a CV joint is an external part that is located on the bottom of the car. This means that all small particles when driving fall on the hinges in the same way as on the rest of the chassis.

On each wheel drive there are two mechanisms, which have almost the same structure, only slightly different in shape and size. As a rule, left and right CV joints are interchangeable on most car models. If you are in doubt, it is better to go to a car service center and ask if it is possible to buy left-handed hinges for right-hand drive on such and such a VAZ model for installation on right-hand drive, or vice versa.

Why does a grenade break?

Sometimes it is necessary to replace the inner CV joint of a Chevrolet Niva. In order to reduce the likelihood of breakdown, you need to know what reasons lead to this. Specialists and experienced car owners identify the following reasons under the influence of which the “grenade” will require replacement or repair:

• the unit is completely out of order;
• the service life has expired (indicated in the vehicle documentation or in the invoices if repairs were previously carried out);
• driving rules recommended by manufacturers are violated - aggressive style, choice of difficult routes, all this negatively affects the details.

Despite the fact that the Chevrolet Niva is an SUV, it is necessary to ensure that difficult road conditions are not constant. The reasons for the “grenade” to fail include dirt, dust or large particles getting into the components.

According to the statistics of requests, in 90% of cases the outer part of the element requires replacement. To reduce the likelihood of an emergency, it is recommended to regularly check the condition of the protective rubber covers and adjust the fastening in the unit.

Caring for front wheel joints

It just so happens that most motorists pay attention to some part of the car after it breaks down. A new CV joint is purchased and replaced, which takes time and considerable money.

In fact, there is no drift to the angular velocity hinges installed in the Niva.

Unlike front-wheel drive VAZ 2110-2114 cars, in the Niva the torque is distributed over 4 wheels. This means that the load on the front wheel drive is half as much as in the same VAZ 2114. And if we theoretically assume that not a drop of abrasive dust and dirt gets inside the hinge mechanisms of the axle shafts, then the service life of the CV joint will be equal to the “life” of the CV joint itself. auto. Of course, this is impossible in real life, and the Niva is designed for off-road driving.

It is quite possible to prolong the life of grenades as much as possible. To do this, you must regularly perform the following activities:

1. Conduct a visual inspection of the anthers covering the hinges. When the car is operated on an asphalt road, an inspection should be carried out every 10-15 thousand km. When driving off-road or on embankment and dirt roads, the grenade cases need to be inspected more often, especially after driving in difficult conditions.
2. If the slightest damage to the boot is detected, immediately replace it with a new one. This also applies to the clamps that hold the covers in place.
3. During replacement, remove old grease from the Niva CV joint along with any dirt that has fallen into it and apply new one. The lubricant used is CV joint-4, its quantity for the outer grenade is 40 cm3, for the inner grenade - 80 cm3.

If you pay attention to these elements, they will easily last 150-200 thousand km

Otherwise, malfunctions may appear within the first hundred thousand km.

Let's start work.

Before starting work, be sure to install the Niva on the handbrake and insert wheel chocks under the rear wheels.

1. Loosen the wheel nuts, place the car on a jack and remove the wheel.

2. Place a secure support under the lower arm. Lower the jack and the lever will compress.

3. Remove the three bolts securing the lower ball joint and unscrew the nuts.

4. Knock the chrome hub cap through a wooden block and unscrew the nut. Make sure that the hub does not rotate; to do this, you can install some kind of stop under the wheel stud. A hammer is ideal.

5. Remove the cone washer.

6. Grasp the bottom of the brake disc and pull it towards you, then move it to the side. At the same time, the grenade axis should be removed.

The Niva CV joint has been released. You need to place it on the bottom cup in any place convenient for you.

Next, your task is to turn the CV joint and find a comfortable position in order to grab the clamp tabs with pliers. Having grabbed the clamp, you should squeeze it well, bend the hook and dismantle it. Leave marks on the car shaft, as well as on the grenade body. This is done so that later, when you put the part back in place, you assemble everything exactly as it was before the repair. When the boot is released, move it away from the grenade.

Now you need to get the wire type retaining ring on the CV joint housing. You can feel it with your finger and, using a screwdriver, pry it off at the break in the ring and remove it.

Grasp the shaft firmly and pull the CV joint of your Niva out of the body.

Causes

Service life too long. If the car has driven 10 thousand kilometers without problems, then the anthers should be changed without waiting for a breakdown.

Sloppy driving. During sharp turns, fast driving “over bumps” and turning the steering wheel, the CV joint takes on the entire load. It can break at any moment, so every car enthusiast should know how to replace the boot on a Niva.

Water, dust and dirt. As a result of damage to the dirt cover, water and dust enter the CV joint. When mixed with lubricant, dirt acquires abrasive properties and leads to damage to the hinge.

Now you know how to change the boot on the Niva’s cardan and how to prevent damage. However, for quality repairs, we recommend turning to specialists.

Chassis Replacement of CV Joints on a Chevrolet Niva Every car has equal angular joints, which are called grenades; they have this name because of their similarity to a military object.

Thanks to it, when turning while driving, torque is transmitted from the engine to the inner CV joint. This element in the car appeared when they began to produce cars with front-wheel drive, and before that, torque was transmitted through a conventional cardan.

Further, it will intensify even with small turns of the steering wheel. Replacement procedure: A set of wrenches, pullers, and plumbing experience will be required.

The body is raised with a car jack, a reliable stand under the car and wheel chocks are installed. This helps protect the repairman from possible injuries.

Before lifting the car body, loosen the hub nut. Initially, torque was transmitted to the drive wheel using a conventional cardan. At the same time, the service life of the hinge was short, since it was constantly working under load.

Inner right CV joint on a Chevrolet Niva - how much does it cost to replace a grenade

This problem gave impetus to the invention of a special CV joint unit that could transmit torque to the wheels at different angles of rotation. It's mostly front-wheel drive. Due to the CV joint, there is a uniform transmission of torque, taking into account the fact that the wheel is located under the corner of the car.

On a Chevrolet, a grenade can be: Outer CV joint Inner CV joint Like all other parts in the car, this unit has its own specific service life.

Part Features

Constant velocity joints - these elements were created specifically for front-wheel drive vehicles; previously, torque was transmitted to the wheels using a simple cardan. Due to the large load on the hinge, the service life of the part was very short. To avoid such a situation, this node was created.

An outer CV joint is needed to transmit torque evenly when the wheel is at different angles. CV joints can be both external and internal.

There are certain parts in the assembly that are constantly moving, so often the parts burst or completely wear out, and this requires their urgent replacement. Repair of the device is carried out when damage to the boot is detected in time, when dirt, dust and other substances do not have time to penetrate inside the grenade.

To identify a breakdown on a Niva, turn the steering wheel all the way in any direction while driving. If there is a problem, then you will hear a characteristic creaking sound in the area of ​​the front wheel. During the repair work, you should determine how many hinges need to be changed - one or two at once. Professionals advise implementing the procedure comprehensively.

Let's put everything back together.

Reassembly should begin by lubricating the shaft and putting the boots and cover back in place. Next, install the retaining rings while holding the shaft securely in a vice.

Now you can install the joint on the shaft. When you feel the splines, you should lower it until it comes into contact with the locking ring located on the outside.

Hit the CV joint with a hammer and force it into place. It is advisable to carry out this operation by installing a soft metal spacer on the part so as not to damage the hinge during an impact. Check the fixation of the part for reliability, do this in both directions.

Reinstall the anthers, followed by the clamps. Calculate the dimensions when installing so that when the car moves forward, the grass does not cling to the clamps. Don't be afraid to put in some serious effort when performing these operations, as this is where you really need to use force.

The work is almost complete, all that remains for you is to install the finished spare part on your Niva and enjoy its work.

Varieties

SR as a suspension part began to be used on cars from the mid-20th century. Thanks to the unit, it became possible to simultaneously rotate and control the rotation of the wheels at an angle of up to 70 degrees. In the automotive industry, four technical solutions for components are used:

• cam;
• tripoid;
• ball;
• twin cardan shafts.

All these types are united by the basic design, which is a rigidly connected body and holder. The car's joints are also divided into:

• internal, rotating up to 20 degrees;
• external, more mobile and transmitting without power losses.

The part works according to the following principle.

1. There are grooves on the surface of the inner race. Their number is the same as the number of bearings inside it.
2. The cage is held in place by bearings that separate the housing and the cam.
3. The bearings move along the path of the smaller diameter of the fist and the larger diameter of the housing.
4. This creates a rotational impulse that transmits torque to the driven shaft.
