Note: Support the body in places specially designed for this purpose.
Remove the rear wheels.
Loosen the brake shoe clearance adjusters through the holes in the brake shield.
Remove the outer brake drum oil cover.
Note: The casing is damaged during dismantling and must therefore be replaced with a new one.
Unscrew the central hub mounting nut (Fig. 4.19).
Note: The nuts have left and right hand threads. The left hand threaded nut is on the left side.
Remove the hub with the brake drum.
Remove the sealing ring (oil seal) from the hub using a special tool (Fig. 4.20).
Remove the inner races of the tapered bearings.
Remove the outer rings without damaging the holes.
Remove old grease and wash the hub.
Installing new rear wheel bearings
Insert the outer races of the new bearings into the hub.
For this purpose, use the 15-051 device. The rings must be installed in such a way that their entire surface rests on the ledge of the hole in the hub.
Insert a new sealing ring (oil seal) using tool 14-028 (Fig. 4.22).
Fill the outer bearing with grease and insert it into the hub.
Place the hub with drum and bearings on the axle journal. Tighten the central hub mounting nut to the recommended torque.
Install a new anti-oil (anti-grease) boot.
The bearings are designed in such a way that clearance is created in the system of both hub bearings automatically as a result of tightening the central nut.
To obtain the correct clearance, it is necessary that the bearings (inner and outer) are made by the same manufacturer. The journal and hub must be in good condition without any damage.
Install the rear wheels of the car and press the brake pedal several times to ensure that the pads are properly seated in the drums.
