Loosen the mounting bolts, remove the brake caliper and secure it to the suspension with a wire hook without stretching the brake hose.
Loosen 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 onto the spring stop.
Place a jack under the main gear housing and lift the main gear. Loosen the rear rubber support of the main gear to the body base and lower the main gear.
Thoroughly clean the surfaces of the final drive housing.
Loosen the mounting bolts and remove the bearing caps.
Using pliers, remove the mounting ring from the inner end of the axle shaft, as shown in Fig. 227.

1 - forceps with bent ends,
2 - mounting ring.
Remove the axle shaft from the axle shaft gear and remove the spacer ring. The axle shaft joints are of the floating type; in the installed axle shaft, the axial movement of the joints is 15-20 mm; when the suspension arm is positioned on the spring stop, the axial movement of the joints is 30 mm.
Since there is an oil drain groove in the seal, it is necessary to pay attention to the designation of the axle shafts during installation. The designations "R" (right) and "L" (left) are applied to the end of the inner end of the axle shaft. The locations of the designations are shown in Fig. 228.
Fig. 228. Designation on the axle shaft.
When installing the axle shaft, perform the following work:
If a new axle shaft is being installed, before installation, put on the spacer ring removed from the old axle shaft (Fig. 229).

2 - rubber cuff,
3 - support sleeve,
4 - rubber cuff,
5 - half-shaft.
Install the half-shaft assembly into the half-shaft gear and place a new installation ring into the groove at the end of the half-shaft. Fig. 230 shows a section of the installation of the inner end of the half-shaft, the position of the spacer ring and the designation of the 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. the axial clearance should not be noticeable.
Finally install the axle shaft and, using the device shown in Fig. 222, press the outer end of the axle shaft into the rear wheel hub.
Screw the axle shaft mounting bolt into the hub and tighten.
Raise the final drive.
Install the bolts securing the rear rubber support to the body base and tighten them.
Lower the jack.
Install the brake caliper with a new retaining plate.
Fill the main gear housing with oil up to the lower edge of the filler hole and tighten the plug.
