Do-it-yourself CV joint repair for Niva Chevrolet driveshaft

In detail: do-it-yourself repair of a drive shaft CV joint for a Niva Chevrolet from a real master for the site my.housecope.com.

Today we have a Chevrolet Niva car, produced in 2012, for repair, on which it is necessary to replace the joint of the propeller shaft. The problem with the CV joint arose due to a torn anther, the owner of the car did not notice this in time, as a result, road dust and dirt got there, and unpleasant sounds appeared when driving.

We get to work, remove the cardan by unscrewing 4 nuts on the bridge on each side (key 13), remove part of the protection. For the convenience of work, the longitudinal jet thrust was unscrewed. We dismantle the gimbal.

Before starting the repair, a Cardan repair kit was purchased, its number in the spare parts catalog: 21214-2201160. The kit includes a boot, grease, separator, two clamps, new nuts, engraver, plugs, stopper and assembly instructions.

Remove the plug using a screwdriver:

Remove the external fixation stopper. From the repair kit, we first install the clamp, then the boot, add the lubricant:

We put on the stopper, while its dimensions did not coincide a little, we had to go to the turner. We take the separator, remove the fixing clamps from it and put it on. We stuff the grease into the separator, in general it was not enough from the repair kit, I had to add a little of my own. We put the cardan in place.

We carry out the work on a viewing ditch or overpass. During operation, you will need to turn the drive shaft, therefore, put the machine in neutral and release the parking brake lever. It is possible to hang the machine on one post from the front or rear (depending on which shaft needs to be removed). In this case, you do not have to roll the car to turn the shaft.

Video (click to play).

The removal procedure for the front and rear drive shafts is the same. We install an adjustable stop under the transfer case. Using the "13" head with an extension cord, we unscrew the four nuts securing the side brackets of the transfer case suspension and two nuts of the cross member of the rear bracket of the transfer case.

We lower the transfer case on the stop so that it comes off the mounting studs.

Turning the shaft with an open-end wrench "13", in turn, unscrew the four nuts securing the shaft to the drive axle flange.

The nuts are equipped with Teflon inserts to prevent spontaneous loosening. It is recommended not to allow repeated use of nuts and promptly replace them with new ones.

To remove the nuts, insert the mounting paddle into the gap between the CV joint and the flange, then press the CV joint so that it slightly moves along the shaft splines and allows you to remove the unscrewed nuts.

Then we squeeze the CV joint with two mounting blades so that the fastening pins come out of the holes in the drive axle flange.

The transfer case, removed from the mounting studs, allows this to be done. If you do not free the transfer case, then the free play of the splined joints of both CV joints will not be enough.

Holding the drive shaft with our free hand, unscrew the four nuts securing the shaft to the transfer case flange ...

Install the drive shaft in reverse order.

As a car from the class of SUVs, the Chevrolet Niva, respectively, is equipped with all-wheel drive.But how, if not a cardan transmission, torque can be transmitted from the transfer case to the wheels. Today we will consider the complete picture of the rear cardan of a Chevrolet Niva car, its features, structure, how it is replaced if faulty breakdowns occur.

The cardan drive is a hollow steel tube. The metal thickness of the tube is 1 to 2 mm. This tube is welded on both sides:

The fork of the second hinge is connected to the splined tip and is put on it. Thus, a splined connection is provided. This connection is necessarily sealed with a gland, which is installed on the slide fork.

So, the torque on the Chevrolet Niva car is transmitted through cardans (front and rear), but we are only interested in the rear. On the Chevrolet Niva, the design of both the front and rear universal joints is almost the same, the difference lies only in the length of the device.

On restyled models, the design of the propeller shaft has an improved look, and on models since 2010, the Chevrolet Niva has been equipped with a drive shaft with hinges of equal angular ends. The components of the rear universal joint of the Chevrolet Niva models up to 2010 and the CV joint shaft of models from 2010 are shown in the photo below.

Image "A" shows a steel base called a shaft (2). On both sides at the ends there are crosses, connected on one side by a shaft flange (1) and a sliding fork flange (4). There is also a sliding fork (3). On the restyled models, the cardan design has already acquired a distinctive appearance from the earlier modifications of the Chevy Niva, and is a shaft with hinges of equal angular velocities (B). The image shows that the shaft consists of a tube (7), the SHRUS device itself (5) on both sides and, of course, anthers. The boot is designed to protect the connection from getting inside not only dust, but also water and dirt. It also keeps the grease from flowing out.

The operability check is carried out on the engaged neutral gear of the PP box. The car is driven onto an overpass or inspection pit and shoes are placed under the wheels so that the car can move without rolling off the overpass. We proceed to verification activities. The check is carried out for both types of structures:

External examination. All joints are inspected, whether there are any loosening of the bolt tightening, in what condition the boot is.
Then, with both hands, the shaft is grasped on the side where the connections are checked, and the shaking is carried out with sharp movements. If there is a slight backlash, then the design is faulty. There should be no backlash.
With sharp movements, it is necessary to turn the shaft around its axis of rotation, while holding the plug-flange of the hinge with one hand. There should be no circumferential gaps.

The vehicle is installed on the flyover. At the checkpoint, the lever is in neutral and the parking brake is in the down position. Shoes are installed under the wheels for safety.

Before carrying out the removal, it is necessary to make notches on the ends of the flanges, the drive axle and the transfer case at the joints. This will help return the shaft to its original position without the need for balancing.

The nut of the cardan bracket is unscrewed, while supporting the bolt so that it does not rotate.

All fastening nuts are unscrewed in the same way. There are four of them on one side. The nuts are Teflon coated to prevent self-rotation.

After removal, even if the shaft is not replaced, it is recommended to replace the nuts with new ones.

Three fastening bolts are removed from one side, and the fourth is left to fix the product in its original position.

We perform operations on unscrewing the nuts from the other side of the fastening. The order of unscrewing does not matter.

The last bolt is removed from one side and the cardan is removed, while its parts are reduced to the slot.

The product has been removed, now it is being repaired, and if it is impossible, it is replaced with a new one. The order of installation is the reverse of removal.

Many Shniv owners drive exactly new models, so it will be relevant for them to present the procedure for removing the universal joint from the CV joint.

You can not hold the shaft, but fix it with a strong rope to the bottom of the car, well, or use the help of a friend.

It is worth paying special attention to such an important question: How to put the boot correctly on the CV joint? This question is replete with its popularity on the forums, but unfortunately few people pay attention to such custom sites. So, how to replace the boot on the cardan with the CV joint of the Niva Chevrolet SUV is described below:

A new boot is purchased, if necessary, two, because one product is located on both sides. The cost of one is about 150-200 rubles.
The cardan is removed, the order is described above.
We take out the device from the pit and proceed to removing the old worn out boot. The plug is removed from the back of the hinge.
The retaining ring is removed from the spline part, and then the hinge is removed.
On the side where the boot is put on, another retaining ring is installed, which must also be removed.
We take out the hinge, and the order of the parts must be remembered. The worn boot is removed.

The boot can be removed by cutting, this sequence of steps is necessary to install a new element.

All parts are washed, then lubricated and put back on.

The boot is initially put on the shaft, and then all the other parts.

Clamps are installed on the boot.

Similarly, the boot is replaced on the other side. Everything is ready to assemble the gimbal into place.

Thus, every driver of a Chevrolet Niva car will be able to independently replace the cardan using this information, regardless of what year of release his SUV is. Successful repair work, dear Shnivavody!

Do you still think that car diagnostics is difficult?

If you are reading these lines, then you have an interest in doing something yourself in the car and really savebecause you already know that:

STO lomat big money for simple computer diagnostics
To find out the error, you need to go to the specialists
Simple wrenches work in the services, but you can't find a good specialist

And of course you are tired of throwing money away, and there is no question of driving around the service station all the time, then you need a simple ELM327 AUTOSSCANER that connects to any car and through a regular smartphone you will always find a problem, pay off CHECK and save a lot.

We have tested this scanner ourselves on different machines and it showed excellent results, now we recommend it to EVERYONE! So that you do not fall for the Chinese counterfeit, we publish here a link to the official website of the AutoScanner.

The cardan drive is a hollow steel tube. The metal thickness of the tube is 1 to 2 mm. This tube is welded on both sides:

Types of cardan shafts

1. Slotted tip;
2. Hinge fork.

Comparison of cardan shafts of the old and new model

Image "A" shows a steel base called a shaft (2). On both sides, at the ends, there are crosses (their purpose and design can be found in the corresponding article), connected on one side by a shaft flange (1) and a sliding fork flange (4). There is also a sliding fork (3). On the restyled models, the cardan design has already acquired a distinctive appearance from the earlier modifications of the Chevy Niva, and is a shaft with hinges of equal angular velocities (B). The image shows that the shaft consists of a tube (7), the SHRUS device itself (5) on both sides and, of course, anthers. The boot is designed to protect the connection from getting inside not only dust, but also water and dirt. It also keeps the grease from flowing out.
Checking the serviceability of the cardan transmission

1. External examination. All joints are inspected, whether there are any loosening of the bolt tightening, in what condition the boot is.
2. Next, both hands grasp the shaft on the side where the connections are checked, and swing it with sharp movements. If there is a slight backlash, then the design is faulty. There should be no backlash.
3. With sharp movements it is necessary to turn the shaft around the axis of its rotation, while holding the plug-flange of the hinge with one hand. There should be no circumferential gaps.

When the design of the device, so to speak, loses the balance of the plates, or all parts of the product are replaced, then upon completion it is imperative to re-balance the propeller shaft. If, after balancing, the product malfunction problems are not eliminated, then the shaft is replaced with all the elements. If the shaft is not balanced, this will gradually lead to an increase in the number of vibrations, especially at a speed of 60-80 km / h.Cardan balancing is carried out either by visiting a service station, where the masters will perform all related work, or independently, which will save finances. But that is another story.Removal and replacement of the propeller shaftRemoval and then replacement of the cardan on Chevrolet Niva trim levels until 2010 is carried out in the following order:1. The vehicle is installed on the flyover. At the checkpoint, the lever is in neutral and the parking brake is in the down position. Shoes are installed under the wheels for safety.
2. Before carrying out the removal, it is necessary to make notches on the ends of the flanges, the drive axle and the transfer case at the joints. This will help return the shaft to its original position without the need for balancing. Image - DIY Niva Chevrolet driveshaft joint joint repair

Shaft nuts

3. Unscrew the gimbal bracket nut while supporting the bolt so that it does not rotate.
4. Unscrew all fastening nuts in the same way. There are four of them on one side. The nuts are Teflon coated to prevent self-rotation.

After removal, even if the shaft is not replaced, it is recommended to replace the nuts with new ones.

5. Three fastening bolts are removed from one side, and the fourth is left to fix the product in its original position.
6. Operations for unscrewing the nuts are performed on the other side of the fastening. The order of unscrewing does not matter.
7. The last bolt is removed from one side and the cardan is removed, while its parts are reduced to the slot.
8. The product is removed, now it is being repaired, and if it is impossible, it is replaced with a new one. The order of installation is the reverse of removal.

Many owners of Chevrolet Niv drive precisely on new models, so it will be relevant for them to present the procedure for removing the universal joint from the CV joint.

Assembling and disassembling a new universal joint joint is sometimes like a game of "Rubik's cube" if the sellers sold the CV joint disassembled and how to put it back together for installation, a piece of paper has its own meaning.

the boot on the CV joint was torn near the bridge, unscrewed the nuts from the studs from the distributor and from the bridge, and I can't remove the gimbal, the pins interfere. To no avail.

In general, from my experience, the easiest way: you unscrew the long jet rods and the cardan falls into your hands

Thanks for the advice I'll try now. But will it work without a pit?

I know that the guys from the forum on the ground unscrewed it and pulled it out with a mounting tool, but it didn't work out for me ... I lifted the car and put it on stands, unscrewed the long rods and the cardan came out perfectly_

Thanks for the advice I'll try now. But will it work without a pit?

Tomorrow, to the pit, the victory. Unscrew the razdatka and move it aside.

This is the correct solution, loosen the handout and the problem is solved good luck in this not an easy matter)))

Our city is not big, it went around all the car dealerships, and there are a dozen of them, and in more than one there is no CV joint on the cardan. I ordered it in one, the cardan joint joint repair kit costs 2,400 rubles. I already think it's not better to put the rear on the crosspieces.

I also think to put the rear cardan on the crosspieces. If I put it on, will the shock disappear when working with the clutch?

try to tighten the nut on the bridge flange. just be careful. do not overtighten the spacer sleeve. maybe she loosened up here and there was a backlash. hence the blows.

The cardan can be removed easily. there is no need to touch any jet rods and handouts. in the normal state, the spline is almost completely retracted into engagement. it is not possible to compress it and remove the studs from the bridge flange, even with a pry bar. you need to unclench. lift the car body with an elementary jack. the distance between the bridge and the body (and therefore the razdatka) begins to increase. the gimbal becomes short. and will fall out of the flange itself. do not overdo it, otherwise you will write how to insert it back, the gimbal will be too short. I don’t get any nuts on the nuts… hahaha good luck!

All the same, the PK had to be loosened, the transverse fastening was completely unscrewed, and the rest of the nuts were loosened, the PK was pulled forward and the Ksrdan was removed. I disassembled the CV joint, washed it, collected there was practically no backlash at all. As a result, I replaced the casing, put in a new lubricant, and let the new CV joint lie in reserve. drove, everything is fine there is no noise. In short, you need to have new anthers in stock and look under the car more often.

Chevrolet Niva has the factory designation VAZ 2123. This car was conceived to replace the outdated VAZ 2121 model. However, both cars are produced today at the VAZ plant and each of them finds its buyer. The Chevrolet Niva VAZ 2123 has more comfort for the driver and passengers. The older Niva Vaz 2121 performs better on serious off-road conditions. It also has a higher front overhang so it can tackle pretty steep inclines.

Both cars have permanent four-wheel drive and a transfer case with a reduction gear. Structurally, the Chevrolet Niva Vaz 2123 and the usual Niva Vaz 2121 have many common nodes. The cars are quite easy to maintain, and replacing some parts that are out of order is not an overwhelming task for an experienced motorist.

Today the Chevrolet Niva Vaz 2123 is produced with modern additional equipment. In particular, they put on the car:

ABS;
Airbags;
Power steering;
Air conditioner.

In its price range, this car has virtually no competitors with an identical off-road potential. However, many criticize the low-power engine that she inherited from the Vaz 2121 model. It was only slightly modified. This motor clearly lacks power. It is only 80 horsepower, which by modern standards is not enough even for a compact city car, not to mention a full-fledged SUV. Hence the rather high consumption of gasoline. In addition, the fact that the four-wheel drive is permanent also has a negative effect on efficiency.

The build quality of the Chevrolet Niva Vaz 2123 has improved significantly in recent years. Spare parts are always available, and there are plenty of services that are ready to service this car throughout the country.

Vaz 2123 or Chevrolet Niva, like its predecessor Vaz 2121, has both rear and front driveshafts. Both nodes are reliable enough. Chevrolet Niva driveshaft consists of elements such as:

Shaft;
Two crosses;
Sliding fork;
Seals and fastening parts.

Rear propeller shaft Niva

Before removing the rear propeller shaft of the Chevrolet Niva, you must set the gear lever to neutral and release the handbrake. In order to maintain the balance of the propeller shaft after installing it back on the car, when removing it, mark, with paint or a punch, the position of the shaft housing and the holder of the differential drive gear shaft crosspiece.

Before removing the bolts and clamps securing the rear end of the propeller shaft to the rear differential, it is necessary to mark the relative position of the holders and the universal joint cross.

The intermediate stage has been passed. Now, to remove the universal joint, unscrew the bolts and remove the clamps of the rear universal joint. To prevent the propeller shaft from turning when loosening the flange bolts, thread a screwdriver through the crosspiece holder. We attach the needle bearing caps to the cross body with tape or insulating tape to avoid them falling when the propeller shaft is removed.

We lower the propeller shaft, namely, its rear. After that, we remove the cardan, or rather, its front part from the transfer case. Having removed the cardan, the transfer case is wrapped in a regular plastic bag. This is necessary to prevent the loss of transmission fluid, as well as to prevent contamination of the internal elements of the removed propeller shaft.

When installing the cardan back into place, you need to use the cross-piece holder clamps. It is necessary to remove the plastic bag from the transfer case and carefully wipe the released surface. Then the propeller shaft is inserted into the transfer case. Next, take the gimbal by the back and set it to its original position. In this case, it is necessary to ensure that the alignment marks coincide. If they do not match, then turn the rear wheels and achieve alignment of the drive pinion flange marks and the marks that are applied to the cardan. Remove the tape or tape that secured the bearing caps and install new clamps and bolts. This is how the propeller shaft is removed and installed.

The intermediate cardan is removed from the Chevrolet Niva for repairs when the crosspiece needs to be replaced, as well as when performing other operations, if its presence on the car can interfere with successful work. The car is driven onto a pit or overpass. On the CV joints there are four nuts of the bolts that fasten them to the flange of the transfer case drive shaft. They are turned away. Then, with the help of a small chisel and a hammer, markings are made on the CV joints. Mark the body of the constant velocity joint and the transfer case flange. Loosen the fastening nuts of the power unit supports and move the unit a couple of centimeters with a small crowbar. After that, it will be possible to remove the studs, which have an intermediate hinge, from the flange holes. This is what needs to be done.

Next, unscrew the nuts of the bolts that attach the elastic coupling to the flange of the secondary shaft of the gearbox. Then remove these bolts from the seats. If you cannot remove them with your bare hands, then you can use a hammer. It is now possible to remove the intermediate propeller shaft. Installing an intermediate propeller shaft on a Chevrolet Niva VAZ 2123 in reverse order.

The Chevy Niva cardan drive is designed to transfer torque from the gearbox to the transfer case and from the transfer case to the front and rear drive shafts.Cardan drive Chevrolet Niva: 1 - front propeller shaft; 2 - intermediate cardan shaft; 3 - transfer case; 4 - rear propeller shaft.Intermediate driveshaft Chevy Niva: 1 - flange of the secondary shaft of the gearbox; 2 - nut; 3 - balancing washers; 4 - elastic coupling; 5 - flange mounting bolt; 6 - body of the hinge of equal angular velocities; 7 - nut; 8 - plug of the hinge body; 9 - intermediate cardan shaft; 10 - flexible coupling flange.Check the driveline from underneath a vehicle on a lift or inspection ditch. The gearbox and transfer case must be in neutral. Check the tightness of all threaded connections, the condition of the crosses and the rubber array of the intermediate shaft elastic coupling (visual inspection).With both hands, grasp the shaft near the Chevrolet Niva cross joint to be checked. Rock each propeller shaft in short, sharp strokes in directions perpendicular to its axis. No perceptible play in the hinges is allowed. Repeat check for all gimbalsTurn the cardan shaft around its axis in both directions with short, sharp movements, keeping the cardan joint flange plug from turning. No perceptible circumferential clearances allowed

Repeat the test on the rest of the universal joints.Splined joints and universal joints require regular grease replenishment. In the absence of lubrication, the spline joint or the needle bearing of the crosspiece wears out with the appearance of play or, conversely, can jam. In either case, the vibration of the cardan transmission appears.You will need: a syringe for injecting grease, grease like Fiol-2U Image - DIY Niva Chevrolet driveshaft joint joint repair

This is how the grease nipple of the spline joint is located, as well as the crosspieces of the universal joint. Use a syringe to pump grease through the grease fittings on the front and rear propeller shafts. Pressurize until fresh grease comes out from under the seals.

To replace or repair the intermediate propeller shaft, a Chevrolet will need a 13 and 19 wrench, a barb and a hammer
