Removing
1. Raise the rear of the vehicle.
2. Remove wheels.
3. Remove the brake drum (Ch. 10).
4. Disconnect the parking brake cable and hydraulic line (Ch. 10).
5. Turn away nuts of a board of a brake.
6. Remove the axle shaft assembly with the brake (photo). If it is not possible to get the axle shaft by hand, then it is necessary to use an impact puller with an adapter, which is installed on the wheel studs.
14.6a Axle and rear axle
1. Stuffing box; 2. Wheel bearing nut; 3. Lock washer wheel bearing; 4. Washer; 5. Wheel bearing; 6. Separating sleeve; 7. Bearing cage; 8. Oil seal; 9. Half shaft; 10. Filling hole; 11. Breather; 12. Drain plug
14.6b Removing the rear axle shaft using an impact puller
7. Pry and remove the outer seal (photo). The oil seal should be changed each time the axle shaft is removed. Press in a new oil seal with a mandrel of suitable diameter.
14.7 Removing the stuffing box
8. Press the bearing off the axle shaft. This operation is recommended to be performed in a car service, as a puller or press is required. If these devices are available, then do the following.
9. Bend the teeth of the bearing nut lock washer (photo).
14.9 Loosen the rear wheel bearing nut by bending the teeth of the washer
10. Loosen the bearing nut with a wrench (photo), for which clamp the axle shaft in a vice through a soft spacer.
14.10 Loosening the rear wheel bearing nut
11. Using a press or puller, remove the axle shaft from the bearing and brake shield.
12. Knock out the gland from the bearing shell (seal to be replaced).
13. If the bearing outer race is damaged, replace the bearing. To do this, knock out the clip from the shell using a brass beard (photo).
14.13 Removing the outer race of the bearing
Installation
14. Using a mandrel of suitable diameter, press a new bearing seal into the shell. Lubricate the seal lips with grease.
15. Carefully tap the bearing outer race with a hammer on the brass mandrel.
16. Install a spacer sleeve on the axle shaft so that the chamfer on the hole faces the side of the axle shaft flange (photo).
14.16 Orientation of the bearing spacer when mounting on the axle shaft
1. Axle flange; 2. Sleeve
17. Using a brass mandrel, carefully press in the bearing.
18. Install the ring and lock washers, orient and tighten the bearing nut.
19. Lock the nut by bending the teeth of the lock washer.
20. Apply grease to the bearing and into the groove on the end of the rear axle beam.
21. Lubricate the splines of the axle shaft with gear oil, apply grease to the seal lips.
22. Install all removed shims (photo).
14.22 Adjusting shims are installed between the end of the rear axle beam and the bearing housing and provide the necessary longitudinal play of the axle shaft
23. If both axle shafts were removed, install one of them. Measure longitudinal backlash of a semiaxis (photo), which should be 0.3-0.9 mm. If the play is not within the norm, then adjust, for which remove the axle shaft and add or remove shims (the thickness of the gaskets is specified in the Technical data).
14.23 Checking the longitudinal play of the axle shaft
24. Install the second half shaft (if filmed) and adjust the play by selecting gaskets.
25. Further assembly is carried out in the reverse order.
