The grenade is a metal mechanism, which is located inside the bearing. There are external and internal grenades (correct name – joint, CV joint). External are installed in the wheel hub VAZ 2108-21099, and transmission. The grenades are not subject to repair, therefore in case of failure it is necessary to replace on new. Special attention should be paid to the anthers, so as sand and water, trapped in the joint, leading to its rapid wear.

The removal of grenades on VAZ 21099

Work should be carried out on a viewing hole or overpass. Put the car on the handbrake and wheel lock stops the rear wheel. Now the most difficult is to break the nuts that secure the grenade to the wheel. This will require the mechanical key 30, and to perform it successfully, you need a good arm. The best option is to make an extension from a section of a pipe.

Next, raise the car on a Jack, put on the prop and take off the wheel. Now you need to disconnect the tie rod from the knuckle of the rack. This is done using a special puller. And a ball bearing just enough to screw, vypressovyvaniem it is not necessary. Try not to damage the boots, otherwise you'll have to change them.

Now that strut is free, you have to turn it to the right or left (depends on which side of the car is working), remove the wheel hub from the constant velocity joint. It needs to fall, it now remains only to remove the inner, which is in the box. What is needed, and a viewing hole, because to do this it is much easier. Pomegranate is extracted with a crowbar.

Setting the grenades and precautions

Together with constant velocity joints it is necessary to change the anthers. Even if the old one was in satisfactory condition, it is better to replace a new one for reliability. You also need to put new hose clamps. Never remove both the inner grenades out of the box. If you take all of them so undermines the position of the differential mechanism, which will lead to the impossibility of installing CV joints.

First remove one grenade in its place install plug. Perfect old inner CV joint. And only after installing the plug, remove the second grenade. In General, the installation of garnet occurs in the reverse order of disassembly. Do not forget to securely tighten all threaded connections. And also change the rings that are used to attach the shafts.
