- loosen the front wheel mounting bolts, remove the hub cap and unscrew the wheel hub mounting nut on the outer hinge housing;
- hang out the front of the car and remove the front wheel;
- disconnect the ball joint of the suspension arm from the steering knuckle by unscrewing the bolts of its fastening;
- moving aside the telescopic strut of the front suspension, remove the splined shank of the outer hinge from the hub;
- drain the oil from the gearbox;
- with an impact puller 67.7801.9524 or with a hammer through a drift, the body of the internal hinge is knocked out of the hole of the side gear;
- remove the wheel drive.
After disconnecting the shafts from the gearbox, it is necessary to fix the side gears with a mandrel or a technological plug so that they do not fall into the gearbox housing.
The wheel drive is installed in the reverse order. At the same time, the retaining ring 13 of the internal hinge housing must be replaced in order to prevent spontaneous separation of the wheel drive and side gear. If it is necessary to replace the axle oil seal, use the mandrel 67.7853.9562 (diameter 56 mm). After installing the wheel drive, pour engine oil into the gearbox.
