Withdrawal
Press lockout -1-.
Loosen nut -2-.
Attention: The nut is screwed with a large tightening torque. For safety reasons, put the wheel on, lower the car, and only then unscrew the nut.
Loosen wheel bolts.
Raise the back of the car.
Remove wheel.
Remove the end silencer of the exhaust system.
Unscrew the bolts securing the axle shaft to the differential gearbox and tie up the axle shaft on the wire. Attention: Do not allow the axle shaft to sag, as the outer constant velocity joint is overloaded.
All models except Compact: Unbolt anti-roll bar from rear axle beam and fold down.
Compact models: Support the diagonal arm with a jack. Unscrew the shock absorber from the diagonal lever and lower the diagonal lever.
If equipped, unscrew and pull out the ABS sensor.
Press axle shaft out of wheel hub. This requires a special tool, such as BMW tools, see illustration. The jumper is screwed with 2 wheel bolts, and the spindle is screwed into the thread, abutting against the axle shaft and pressing it out. The spindle and axle shaft are connected by a threaded part.
Remove half shaft.
Installation
Put the axle shaft and tie it on the wire.
Press in the axle shaft using a special tool, eg BMW threaded rod 332119 with nut 332115. To do this, first fully screw the spindle into the web. Screw the threaded part onto the spindle and onto the axle shaft. On the other hand, screw the nut onto the spindle and clamp the jumper. In this case, the axle shaft will be pressed into the hub. Check the alignment of the splines on the axle shaft and in the hub.
Lubricate the contact surface of the new nut with a flush and lightly screw on the nut.
Screw the axle shaft to the differential gearbox with a torque wrench. The tightening torque depends on the thread size of the bolts. Thread M10: 85 nm; thread M8: 65 nm. Don't forget to put spacers on.
Remove axle suspension wire.
Install the end silencer.
Compact models: Install shock absorber.
Put the wheel on, lower the car.
Tighten the nut with a torque of 200 Nm.
Lock the nut with the tide, for which drive the tide of the nut with a drift into the recess on the axle shaft.
Tighten wheel bolts to 110 Nm.
Bring the car to normal, that is, it must be on wheels and have a normal load. Screw the stabilizer to the rear axle beam.
