Removal
1. Mark the position of the front wheels relative to the hub with paint. This will allow you to install the balanced wheel in its original position during assembly.
2. Loosen the wheel mounting bolts. The car must stand on its wheels when performing this operation.
3. Place the front of the vehicle on jack stands, unscrew the wheel bolts and remove the front wheels.
4. Carefully knock off the cap 1 of the hub nut with a rubber mallet (see illustration).
5. Install the wheels.
6. Lower the car onto its wheels.
7. Bend back the cotter pin 1, remove it and loosen the nuts 2 of the hub on the vehicle standing on its wheels. It is not necessary to completely unscrew the nuts (see illustration).
8. Place the front of the car on stands, remove the front wheels and unscrew the hub nuts.
9. Unscrew the bolts that secure the lower wishbone to the cross beam, see the relevant chapter. Mark the bolt locations for proper installation during subsequent assembly, as the bolts vary in length.
10. Press out the axle shaft ends from the hubs using a standard puller 1 (see illustration).
11. Unscrew the bolts securing the support bracket of the right axle shaft and intermediate shaft to the cylinder block.
12. Using a suitable screwdriver, pry the intermediate shaft end out of the transmission gear.
13. Using a suitable screwdriver, pry the left axle shaft out of the gearbox.
14. Clean the splines of the front drive axle shafts and the surfaces mating with the axle shaft flange.
Installation
15. Check the elasticity of the thrust ring on the left axle shaft tailpiece, which secures it to the gearbox. Replace the ring if necessary.
16. Turn the thrust ring with the hole facing down, carefully insert the left axle shaft end into the splined hole on the gearbox until it stops and secure with the retaining ring.
17. Carefully insert the intermediate shaft end of the right axle shaft into the splined hole on the gearbox until it stops.
18. Carefully adjust the threads of the holes for the support bracket mounting bolts on the cylinder block using a suitable tap.
19. Secure the support bracket to the cylinder block with new self-locking bolts and tighten to 20 Nm.
20. Apply the Teflon-forming aerosol to the mating surfaces of the front axle shafts and their flange in three passes. Allow each coat to dry slightly between sprays.
21. Insert the drive axle shafts into the holes on the hubs until they stop. Make sure that the axle shaft flange does not shift.
22. Secure the lower wishbone to the axle beam by screwing new nuts onto the bolts. Remember that the bolts are different lengths.
23. Tighten the nuts to a torque of 105 Nm.
24. Screw new hub nuts onto the axle shafts.
25. Install the wheels and lower the vehicle.
26. Tighten the nuts on both hubs. The car should stand on its wheels.
Tightening of the hub nuts is performed in several passes:
- 1st pass: Tighten the nut to 180 Nm.
- 2nd pass: Loosen the nut completely.
- 3rd pass: Tighten the nut to 80 Nm.
- 4th pass. Tighten the nut with a wrench by 45°.
27. Place the front of the vehicle on stands and, after unscrewing the wheel bolts, remove the front wheels.
28. Tap the protective cap onto the hub nuts with a rubber mallet, being careful not to damage the cap.
29. Install the front wheels according to the marks made during removal. Before doing this, lubricate the seat of the disk of each wheel on the hub with a thin layer of bearing grease. Do not lubricate the wheel mounting bolts. Screw in the wheel mounting bolts and lower the car. Tighten the nuts in a crosswise order with a torque of 110 Nm.
