Removal
Loosen the wheel bolts.
Raise the rear of the car.
Remove the wheel.
Press the lock "1".
Unscrew nut "2".
Attention: The nut is tightened with a high tightening torque. For safety reasons, put the wheel on, lower the car and only then unscrew the nut.
Loosen the bolts securing the axle shaft to the differential gearbox using a 6 mm Allen key, such as the HAZET 2584 (arrows) and tie the axle shaft with wire.
Caution: Do not allow the axle shaft to sag, as this will overload the outer constant velocity joint.
Press the axle shaft out of the wheel hub. This requires a special tool, such as BMW 332110 with spindle 332111, bridge 332112 and threaded part 332113. The bridge is screwed with "2" wheel bolts, and the spindle is screwed into the thread, resting against the axle shaft and pressing it out. The spindle and axle shaft are connected with a threaded part.
Remove the axle shaft.
Installation
Install the axle shaft and tie it with wire.
Screw the axle shaft to the differential gearbox with a tightening torque of 80 Nm.
Press the axle shaft in using a special tool, such as BMW 332110. To do this, first screw the spindle completely into the bridge. Screw the threaded part onto the spindle and onto the axle shaft. On the other side, screw a nut onto the spindle, such as BMW 334042, and clamp the bridge. In this case, the axle shaft will be pressed into the hub. Make sure that the splines on the axle shaft and in the hub match.
To hammer in a new counter.
Lubricate the contact surface of the new nut and lightly screw the nut on.
Put the wheel on and lower the car.
Tighten the nut to a torque of 200 Nm.
Tighten the wheel bolts to 110 Nm.
