Removing and installing hinges
1. After removing the axle shaft from the vehicle, it can be disassembled for parts to check for wear.
2. Rubber boots, spring rings, thrust washers and sealing washers can be replaced with new ones, however the parallel joints can only be replaced as complete units. It is not possible to fit new outer shell pivot hubs, baskets or pivots individually as they are all matched to a certain tolerance during assembly at the factory. The hinge repair kit includes a rubber boot, a tube of special grease, clamping bands and washers. When buying a hinge, you must specify the model of the car, since the hinges differ depending on the model of the car.

3. Fix the axle shaft in the soft cheeks of the vice as close as possible to the hinge.
4. Release the clamp and remove the end of the rubber boot from the hinge.
5. Hitting the outer housing of the hinge with a copper hammer, knock it off the drive shaft. The direction of 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 you to move the hinge hub from the axle shaft splines. It would be nice to additionally delay the short axle shaft 16 during hammer blows.
6. Remove bevel gear 13 and spring gear 12 from the axle shaft, paying attention that the concavity is directed towards the hub of the joint being disassembled (photo 7.4).
7. Remove the clamping band 10 and remove the rubber casing of the axle shaft.
8. Mark the position of the hub in relation to the basket and the hinge body. This is best done with a hard center punch or paint. This designation will be necessary in case of disassembling the hinge into parts. The designation of the hub in relation to the housing is significant for two reasons.
First. The hub, after assembly, must face the corresponding side out of the hinge.
Second. If an old joint is being installed, the hub must be installed in the same position with respect to the joint body. This is significant due to the previous mutual grinding of the ball to the grooves in the hub and in the hinge body.
