How to independently remove the right drive on a Niva-Chevrolet


Front wheel drives Niva Chevrolet

Chevy Niva front wheel drive: 1 – internal joint housing; 2 – clamp; 3 – clamp for securing the cover; 4 – wheel drive shaft; 5 – protective casing; 6 – protective cover; 7 – thrust ring of the cage; 8 – separator; 9 – clamp; 10 – ball; 11 – outer hinge cage; 12 – retaining ring; 13 – outer hinge body; 14 – clamp for fastening the casing. Torque is transmitted to the front wheels from the front axle gearbox through the right and left drives. Both drives are identical in design. Each drive consists of a shaft 4 and two joints of equal angular velocities installed on its splined ends. The internal joint housing 1 is connected to the side gear of the front axle reducer. The outer joint housing 13 is connected to the front wheel hub. The holder 11 is connected to the housing 13 through balls 10, which are located in the grooves of the housing and the holder. The race is installed on the splines of the shaft 4, rests against the ring 7 and is fixed on the shaft with a retaining ring 12. In the compressed state, this ring freely passes through the splined connection of the race 11, which allows you to both connect and separate the hinge and the shaft. The inner hinge body 1 differs from the outer hinge body 13 in that it has straight grooves.

Dismantling and assembling front wheel drives of Niva Chevrolet (replacing the CV joint of the drive)

If you hear knocking noises in the front-wheel drive while driving when turning the car, check the constant velocity joints. If, when rocking the drive shaft by hand, play is felt or the dirt-proof covers are torn, such a hinge must be replaced. There is practically no point in disassembling the hinge. This is labor-intensive work, and if the cover is torn, dirt that has gotten into the hinge has already rendered the hinge parts unusable. The hinge parts cannot be replaced individually, and therefore the best option is to replace the hinge assembly, as well as its dirt-proof cover. As a last resort, disassembly is allowed to replace the grease of the internal joint as it is less susceptible to water and road dirt. The appearance of traces of grease on the hinge indicates that the cover is torn.

To replace CV joints on a Chevrolet Niva, you will need a screwdriver, sliding pliers and a hammer.

Using a screwdriver and sliding pliers, remove the large and small clamps from the inner joint cover

Slide the boot along the drive shaft

  2. Vibration and noise in the area of ​​the front axle, which occurs when the wheel drive shaft is deformed. It can only be eliminated by replacing the damaged part.
  3. Leakage of lubricant from CV joints. The cause of the malfunction is a damaged boot, which must be replaced immediately. If this is not done in time, you will also have to change the CV joint, which quickly wears out when dirt gets in.

Basic malfunctions of the Chevy drive grenade

There are 4 main signs that the constant velocity joint needs to be replaced or repaired:

Malfunctions of CV joints occur as a result of manufacturing defects, incorrect installation of a part, lack of lubrication, driving at high speed over potholes, or natural wear of rubbing parts.

Important! Internal and external constant velocity joints wear out especially quickly when the boot is damaged. In this case, lubricant leaks from the CV joint, and instead the bearings are filled with abrasive particles of sand and dirt.

Checking the hinges is carried out in three stages:

If a breakdown is detected, the parts must be replaced with new ones.

Replacement

Before carrying out work, it is necessary to provide access to the lower part of the car by installing it on an overpass or inspection hole.

To change drives you will need:

  • Balloon wrench.
  • Jack.
  • Keys for 13, 17 and 27.

Replacing the drive is done as follows:

  • Unscrew the cardan from the front gearbox.
  • Jack up the car.
  • Remove the front wheels.
  • Unscrew the shock absorbers from the lower control arms.
  • Unscrew the nuts holding the CV joint bearing housings.

  • Unscrew the fastening and move the exhaust pipe away from the exhaust manifold (this operation is necessary when replacing the right-hand drive).
  • Pull the gearbox back.
  • Remove the drive.

Installation is performed in the reverse order of removal.

Important: when tightening the wheel hubs, it is necessary to adjust the clearances in the wheel bearings.

Replacement procedure: step-by-step algorithm

There is no point in repairing a worn-out unit, so the outer CV joint of a Niva Chevrolet is always replaced. Replacing a damaged “grenade” is a labor-intensive operation. You will need a set of wrenches, pullers, and experience in performing plumbing work.

Outer CV joint

The damaged unit is replaced using an axle shaft with grenades removed from the vehicle. 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. You will need a head and an extension for the key. Next, you need to remove the wheel and unscrew the lower mount of the front shock absorber. Take it to the side and secure it with improvised means. Also unscrew the bolts on the ball joint.

Then they completely remove the nut on the hub and, pulling it towards themselves, take out the “grenade”.

The outer joint can be replaced without removing the axle shaft.

Release the boot mounting clamp and move it as far as possible on the axle shaft. A hammer with an extension is used to hit the body of the “grenade” until it is removed from the axle shaft. Before installing a new part, be sure to change the retaining ring on the axle shaft, since it is disposable. Installing the hinge is done in the reverse order.

Inner CV joint

This faulty unit on a Chevrolet Niva can only be replaced after the axle shaft with constant velocity joints has been completely removed. The “ear” and skis are released, which will allow you to rotate the bridge when removing the axle shaft. For ease of operation, the dismantled axle shaft with “grenades” should be clamped in a vice. Replacing the internal CV joint of a Niva Chevrolet occurs as follows:

  1. Remove the clamps securing the protective boots and move them as far as possible.
  2. Use a hammer and extension to remove the damaged “grenade”. A few blows are enough to dismantle the faulty part.
  3. Before installing a new hinge, carefully clean the splines and install a new retaining ring, since it is disposable.
  4. A new CV joint is installed on the axle, the protective cover is additionally filled with lubricant, and the boot is clamped with a clamp.

The axle shaft with new grenades is assembled and mounted in the reverse order. The process is fully presented in the video:

It will be possible to extend the service life of constant velocity joints if you monitor the condition of the protective covers on the grenades, avoid bad roads and use only high-quality spare parts.

Replacing oil seals

To change the drive seals, in addition to the listed tools, you will need:

  • mount;
  • flat screwdriver;
  • wooden block;
  • hammer;
  • hex wrench 12;
  • puller (two- or three-legged);
  • mandrel (a piece of pipe whose diameter corresponds to the size of the seals);
  • circlip puller;
  • dynamometer.

Before replacing the seals, the drives will have to be removed.

To replace the drive gear seal, you must perform the following steps:

  • Using a dynamometer, measure the starting torque of the drive gear.
  • Fix the flange: screw a couple of bolts into its holes and insert a pry bar into them.
  • Unscrew the fastening nut.
  • Remove the washer and flange from the splines (here you will have to use a puller).
  • Using a flathead screwdriver, remove the oil seal from the mounting hole.

Replacing the drive oil seal is done as follows:

  • Remove the retaining ring and spring washer.
  • Using a hammer, knock the bearing out of its seat.
  • Remove the cover together with the oil seal
  • Knock out the old part using a pipe.
  • Lubricate the new oil seal with grease and press it into the cover.
  • Assemble the knot.

Considering the low price and high labor intensity of replacing the oil seal, during repairs you should not skimp on components and use parts from trusted manufacturers.

What is a CV joint (grenade)

Before the advent of cars with a front wire, such a part as a CV joint was not used in the configuration. The torque to the wheels came from the power unit. A cardan shaft was involved in this. Once front-wheel drive was introduced, the wheels needed to turn easily. If a cardan was installed on the car, it became impossible to carry out the procedure.

Specialists needed to replace some of the elements and develop a special part, which was called a CV joint. The abbreviation stands for constant velocity joint. Now it is he who is used on SUVs with front-wheel drive to transmit torque.

The part is also installed on the Chevrolet Niva. Parts are also installed on some models with all-wheel drive . The function of the units remains unchanged and ensures movement of the drive wheels. Drivers call the CV joint a “grenade.” This is due not only to its low weight, size and characteristic appearance. Additionally, it is worth considering that as a result of the failure of the spare part, it will be impossible to control the machine.

Step-by-step instructions for replacing the inner and outer CV joints in a Chevrolet Niva

Vehicle safety is an important element before using it. With the advent of front-wheel drive, a special part began to be installed on SUVs - a CV joint. Its malfunctions can cause serious damage. That is why it is important to know the first signs of failure of this element.

Step-by-step instructions for replacing the inner and outer CV joints in a Chevrolet Niva will be given below.

CV joints on Chevrolet Niva: what elements are there

Uniform transmission of torque on the driving (in the case of the Chevrolet Niva, front) wheels ensures maneuverability and smooth ride. Reliability on the road is the basis of safety, so maximum attention should be paid to the condition of all components.

According to the design features, the parts are distinguished:

It is worth considering that the wheel will turn smoothly and quickly if all elements in the assembly are in good condition. There are features in the design of the Chevrolet Niva that do not allow rotation to be transmitted to the wheel using a single CV joint. It is for this reason that two of these parts are always installed in the front drive.

It is also necessary to take into account that the parts experience loads of different intensity. The one located near the gearbox fails faster, since the pressure on the part is higher. It is not difficult to visually distinguish the element - the internal hinge is larger in size than the external one. The task of the second element in the pair is to transmit rotation directly to the wheel. The small dimensions are explained by the limited free space in the area of ​​the drive wheel.

Why does a grenade break?

Sometimes it is necessary to replace the inner CV joint on 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.

Signs and manifestations of malfunction

To carry out timely repairs, you need to pay attention to signs of malfunction.

If problems arise with the CV joint, the driver may encounter the following symptoms:

  • a characteristic unpleasant, sharp sound appears when turning the steering wheel;
  • the sound occurs when reversing;
  • slight crunching sound when turning the leading front ears;
  • increased crunching and sharp sounds while moving.

The part will need to be completely replaced if shocks occur in the transmission. Slipping also indicates the need for urgent repairs. If the Niva is often used for transportation, how does four-wheel drive work, what maintenance procedure should be found out in advance.

Why is it necessary to replace the CV joint on a Chevrolet Niva and how to determine it?

Using a hammer, the CV joint is knocked out from the axle shaft. This is done by tapping the grenade with a hammer.

About boots on CV joint cardans for Niva

After the grenade is removed, the old boot is removed and all the teeth of the CV joint axle shaft are cleaned. You can even wash it with gasoline and lubricate it with Litol.

The price of a new assembled grenade ranges from up to rubles. It is mainly sold together with a boot and lubricant inside. First, the boot is threaded onto the axle shaft, and then the grenade is fixed.

The cost of spare parts was rubles.

And by the way, it’s also cheap, I called 3 stores in our city in advance and the prices are different everywhere. So don’t rush to run to the first store you come across.

For example, I saved rubles on these same spare parts if I bought them in the store that is closest to the service.

This could be sharp turns, driving on an uneven road at high speed, or turning the steering wheel when the car suddenly starts. In all these cases, the maximum load is placed on the CV joint. Water, dust or dirt has entered the device.

For this reason, the hinge may also fail prematurely. Water gets inside due to damage to the rubber boot. The protection can crack due to any factors during operation, so it is recommended to periodically check its condition.

Why can the CV joint on a Chevrolet Niva deteriorate?

Such parts tend to wear out, like all others, so they need to be replaced over time. Among the main reasons for which the CV joint will need to be replaced are the following:

  • long service life of the outer CV joint - most often the part has to be replaced after 10 thousand kilometers;
  • entry of dust or dirt when the rubber boot wears out (therefore you need to check the condition of the protective part).

In addition, a large load is placed on the Chevrolet Niva grenade when the steering wheel is turned at strong turns, and driving occurs on poor road surfaces.

Having become familiar with all the features of the hinges, an experienced driver will be able to correctly replace the outer CV joint for a Chevrolet Niva on his own.

Signs and manifestations of malfunction

To carry out timely repairs, you need to pay attention to signs of malfunction.

If problems arise with the CV joint, the driver may encounter the following symptoms:

Step-by-step instructions for a quality replacement

If the unit has just begun to signal a problem, then repair work can extend its service life. If it is completely worn out (diagnosis is recommended at a service station), it makes no sense to carry out work to resuscitate the parts or put the mechanism in order - a complete replacement is required.

In most cases, if there is severe wear, the outer CV joint on a Chevrolet Niva is replaced. It is important to remember that the upcoming process will require time and effort. The car needs to be driven to a special pit to facilitate access to the components and the CV joint itself.

Tools:

  • wrenches (set);
  • hammer with extension;
  • pullers

Experience in plumbing is required if the replacement is carried out in-house.

Replacing the outer CV joint

To change the outer part of the pair in the assembly, you will need to completely remove the axle shaft with the “grenades” installed on it from the car. The sequence of actions in this case is as follows:

  • the body needs to be lifted (a car jack is used);
  • install a stand to minimize the likelihood of an accident if the jack fails to cope with the task;
  • Anti-recoil shoes are installed.

Grenade replacement

This unit consists of parts that are constantly in motion. As a result, they may burst or wear out , requiring replacement.

The device can only be repaired if the owner of the car has identified damage to the boot in time, and therefore foreign substances have not yet managed to get inside the mechanism.

But this happens quite rarely, since it is almost impossible to detect damage to the boot in time. It should also be said that the cost of the CV joint is not high, and therefore it can be purchased if necessary.

Troubleshooting

You can determine the malfunction of the grenade yourself . To do this, while the car is moving, turn the steering wheel in any direction until it stops. In this case, the driver will hear a crunching sound in the area of ​​the front wheel. In this case, you need to replace the hinge.

During the repair process, it is important to determine whether it is necessary to change both hinges or one, because such work is recommended to be carried out only in a comprehensive manner.

Changing a grenade on a Niva Chevrolet with your own hands

To replace a grenade, you must first remove the old one. In the process, you will have to dismantle the axle shaft along with the CV joint (you can find a disassembly video on the Internet). Then the car owner must perform the following actions:

  1. Clamp the removed assembly in a vice.
  2. Remove the old boot.

  3. Knock the CV joint off the axle using a hammer and a socket.
  4. Clean all teeth on the axle gear.
  5. Install the new joint on the axle.
  6. Place the boot and secure it with clamps.
  7. Install the axle with CV joint on the car.

At this point, the repair work on removing the front wheel drives on the Niva Chevrolet has been completed. How to remove the front wheel drives of a Niva Chevrolet Published Removing the front wheel drives on a Niva Chevrolet car is carried out for disassembling and repairing them, removing the right drive of a Chevrolet Niva also when carrying out other work in which their presence will interfere. Move the steering knuckle to the side.

Or you can screw on one nut and hammer the threads on the end of the stud.

A flattened thread will prevent the nut from twisting and the stud from coming out. Unscrew the ear mounting bolts. Unscrew the ski from the stabilizer.

We need to unscrew the left ear and the ski so that we can twist the bridge a little when pulling out the CV joint. We rotate the right ear along the axis upward. To prevent the drive from interfering, it can be removed.

Replacing the left drive of a Niva Chevrolet

In Niva Chevrolet cars, the grenade is presented in the form of a constant angular velocity hinge. This name of this node comes from its similarity to a military node. It is also called CV joint; it transmits torque in the car, from the engine itself to the wheels, at different steering angles.

This element appeared at the time when front-wheel drive cars began to be produced, and before that, the transmission of torque to the wheels occurred through a conventional cardan. And since the joint was constantly under load, its service life was short, and this problem led to the creation of a special CV joint unit, which could transmit torque to the wheel at different angles when turning.

Types of CV joints

This element helps to transmit torque evenly, while taking into account the fact that the wheel can be at different angles relative to the car. They come in two types:

These parts, like any other, wear out over time, so sooner or later the vehicle owner comes to the conclusion that they need to be replaced. Let's take a closer look at the reasons why replacing the outer CV joint on a Niva Chevrolet is necessary and why it fails.

  • A common reason for failure is the longer service life of the part. As a rule, replacement is required after ten thousand kilometers, but replacement may be required earlier
  • Driving on a broken road, sharp turns, the steering wheel is turned all the way at speed, at these moments the maximum load occurs on the CV joint
  • If dust, dirt, or water gets in due to wear of the rubber boot, this also provokes a breakdown earlier than stated. Therefore, you should periodically check the condition of the protection.

Replacement

To change the outer CV joint, it is necessary to remove the grenade jet; it can only be dismantled together with the axle shaft; when the procedure is completed, the following steps must be taken:

  1. We clamp the removed unit in a vice
  2. Removing the old boot
  3. We knock down the CV joint with a hammer
  4. We clean all the existing teeth on the axle gear
  5. We install a new hinge on the axle
  6. We put the boot on and clamp it with clamps
  7. Putting everything in place

Quite often, Chevrolet Niva car owners resort to tuning the engine, as a result of which its power increases, thereby increasing the load on the CV joint and cardan shafts several times, and in order to avoid rapid wear of these parts, it is recommended to strengthen the shaft.

Therefore, if you know all the features of these parts, then you will always determine why one or another element failed, and you will be able to replace it at any time yourself.

Why is it necessary to replace the CV joint on a Chevrolet Niva and how to determine it?

The wear of a CV joint is determined quite simply. You need to drive a circle, turning the steering wheel to the very end, right or left. When driving this way, this part experiences maximum load, which is exactly what is needed to determine breakage or wear.

Parts and consumables:

To do this, you need to unfasten the clamp and remove the boot from the grenade. We take out the bolts and disconnect the ball from the lever. We move the steering knuckle to the side.

Next, disconnect the exhaust pipe from the exhaust manifold and the converter. Move the gearbox back a little and remove the drive.

We dismantle the left drive in the same way. At this point, the repair work on removing the front wheel drives on the Niva Chevrolet has been completed.

Make the necessary repairs, then install in the reverse order. The hub nut is tightened to a large torque.
