Removal and installation hinges
1. After removing the axle shaft from the vehicle, it can be disassembled into parts to check for wear.
2. Rubber boots, spring rings, thrust washers and sealing washers can be replaced with new ones, but parallel joints can only be replaced as complete units. It is not possible to install new outer housing joint hubs, baskets or joints separately, as they are all matched to a certain tolerance during assembly at the factory. The joint repair kit includes a rubber boot, a tube of special grease, clamping bands and washers. When purchasing a joint, it is necessary to specify the car model, as joints differ depending on the car model.

3. Secure the axle shaft in the soft jaws of a vice as close to the hinge as possible.
4. Loosen the clamp and remove the end of the rubber boot from the hinge.
5. Using a copper hammer, hit the outer casing of the joint to knock it off the drive axle shaft. The direction of the blows is shown in photo 7.3.
During operation, the spring ring 14 makes it impossible to extend the axle shaft from the hinge hub 15. Under the influence of hammer blows, the ring bends in the groove and allows the hinge hub to be moved from the axle shaft splines. It would be good to additionally pull the short axle shaft 16 during hammer blows.
6. Remove the cone gear 13 and spring gear 12 from the axle shaft, paying attention to the fact that the concavity is directed towards the hub of the joint being disassembled (photo 7.4).
7. Remove clamping belt 10 and remove the rubber axle shaft cover.
8. Mark the position of the hub in relation to the basket and the hinge housing. This is best done with a hard center punch or paint. This marking will be necessary if the hinge is disassembled into parts. Marking the hub in relation to the housing is important for two reasons.
First. After assembly, the hub must be facing the appropriate side outward of the joint.
Second. If an old joint is installed, the hub must be installed in the same position relative to the joint housing. This is essential due to the previous mutual grinding of the ball to the grooves in the hub and in the joint housing.
