1. Drain the gearbox oil (see «Changing the oil in the gearbox»).
2. Remove the front wheel covers (if they are installed).
3. Prying off with a screwdriver, remove the protective caps of the front hubs.
4. Loosen the front hub nuts by straightening the bent collars of the nuts.
5. Loosen the wheel bolts and hub nuts. The hub nuts are tightened with a large torque, so it is recommended to use, for example, a piece of pipe as a lever.
6. Brake the vehicle with the parking brake, place jack stands under the rear wheels and raise the front of the vehicle to secure stands. Remove the front wheels. After that, finally unscrew the hub nuts and remove the thrust washers installed under them.
7. Disconnect the steering knuckles from the suspension arms by unscrewing two ball joint bolts on each side.
8. Pushing the shock absorber strut outward, remove the splined shank of the inner hinge housing of the left front wheel drive from the wheel hub.
9. Similarly disconnect from a nave the right drive of forward wheels.
10. Using a spudger, press the inner joint shank out of the differential axle gear and remove the left front wheel drive.
11. Press the right front wheel drive out of the axle shaft gear and remove it.
12. Before installing the front wheel drives on the car, be sure to replace the circlips on the tails of the internal hinge housings, otherwise the drive may spontaneously pop out of the side gear while driving. 13. To install the front wheel drive, first insert the splined shank of the outer joint housing into the wheel hub, install the thrust washer and screw the hub nut until it stops without completely tightening it.
14. Then insert the splined shank of the inboard joint housing into the inboard joint oil seal and rotate the drive shaft slightly to align the splines of the shank and the axle gear.
15. Pull down the front suspension arm and with a sharp movement of the shock absorber strut with a steering knuckle, press the drive into the axle shaft gear until the drive is fixed with the retaining ring.
16. Check the reliability of the fixation of the drive in the axle gear: grasp the fist of the shock absorber with your hands and try to forcefully pull the hinge shank out of the gearbox. If this succeeds, try again to press the drive into the gearbox. If after the second attempt it was possible to remove the drive by hand, replace the retaining ring with another one.
17. Install the second front wheel drive in the same way by removing the technological plug from the axle shaft gear.
18. Attach the ball joints of the shock absorber struts to the steering knuckles (see point 7).
19. Install the wheels and tighten the wheel bolts until they stop, without completely tightening them.
20. Install the car on the wheels, removing it from the supports, and tighten the hub nuts to the torque specified in Annex 1.
21. Lock the hub nuts by bending (e.g. with a blunt chisel) lock collars of nuts into the grooves of the shanks of the outer hinge housings.
22. Install hub caps.
23. Tighten the wheel bolts to the torque specified in Annex 1.
24. Install wheel covers.
