Unscrew the mounting bolts, remove the brake caliper and fasten it to the suspension with a wire hook without pulling the brake hose.
Unscrew the bolt securing the axle shaft to the rear wheel hub and press the axle shaft out of the hub, as shown in Fig. 222.
If necessary, unscrew the fastening of the upper end of the shock absorber and lower the suspension arm to the spring stop.
Place a jack under the final drive housing and raise the final gear. Unbolt the rear rubber mounting of the final drive to the base of the body and lower the final drive.
Thoroughly clean the surfaces of the final drive housing.
Loosen the mounting bolts and remove the bearing caps.
Use pliers to remove the adjusting ring from the inner end of the axle shaft, as shown in fig. 227.

1 - tongs with bent ends,
2 - adjusting ring.
Remove the axle shaft from the axle gear and remove the spacer ring. The hinges of the semi-axle are of a floating type, in the installed semi-axle the axial movement of the hinges is 15-20 mm, with the suspension arm positioned on the spring stop, the axial movement of the hinges is 30 mm.
Because there is an oil drain groove in the stuffing box; during installation, pay attention to the designation of the axle shafts. On the end face of the inner end of the axle shaft, the designations are applied "R" (right) And "L" (left). Places of drawing of a designation are shown in fig. 228.

When installing the axle shaft, perform the following work:
If a new axle shaft is installed, put on the distance ring removed from the old axle shaft before installation (pic. 229).

3 - support sleeve,
4 - rubber cuff,
5 - half shaft.
Install the half shaft assembly into the half shaft gear and put a new adjusting ring into the groove of the half shaft end. On fig. 230 shows a section of the installation of the inner end of the axle shaft, the position of the distance ring and the designation of parts.

Check the axial clearance between the inner end of the axle shaft and the differential housing. As already described in section 14.2.2. axial clearance must be imperceptible.
Finally install the axle shaft and using the tool as shown in fig. 222 Press the outer end of the axle shaft into the rear wheel hub.
Install the axle shaft bolt in the hub and tighten.
Raise main gear.
Screw in the bolts securing the rear rubber support to the base of the body and tighten them.
Lower the jack.
Install the brake caliper with a new locking bar.
Fill the crankcase with oil along the lower edge of the filler hole and tighten the plug.
