Withdrawal
The drive shafts have different lengths. On the left is a shorter drive shaft, on the right is a longer one. If both drive shafts are removed, they must be marked before removal.
1. Knock down flats with a chisel and unscrew collar nut -1-.
The nut is very tight. Therefore, for safety reasons, unscrew the nut when the vehicle is on wheels. To prevent the wheel from spinning, ask an assistant to press the brake pedal.
2. Mark with paint the position of the corresponding rear wheel relative to the hub. This will allow the assembly to install the balanced wheel in its original position. Loosen the wheel bolts with the vehicle on the ground. Raise the rear of the car, put it on stands and remove the rear wheel.
3. Disconnect the rear exhaust system, lower it and support it.
4. Disconnect the anti-roll bar -1- from the rear suspension beam (arrow illustration) and take it down. Note: The illustration shows only the left attachment.
5. Remove the collar nut from the drive shaft.
6. Turn off six (arrows in the illustration). Squeeze it from the driven flange and hang it, securing it with wire.
The illustration shows only three mounting screws.
7. This requires a suitable or BMW tool, refer to illustration. Puller 332116 is attached with two wheel bolts, and screw 33211 is screwed into the drive shaft by screwing into the threaded element 332117. As a result, the drive shaft is pressed out.
8. Remove the drive shaft.
Installation
1. Drive the drive shaft and hang it on the wire.
2. Pull in the drive shaft using, for example, bridge 332116 and screw 332119 from screw bush 332115. In doing so, first screw the screw onto the drive shaft. On the other side of the screw, screw the threaded bushing onto it and turn it towards the jumper. Thus, the drive shaft is drawn into the hub. Make sure that the splines of the drive shaft and the hub match before retracting.
3. Lightly grease the mating surface of the nut and screw it on.
4. Bring the drive shaft to the differential. Screw in Torx screws with straps and tighten to 65 Nm.
5. Remove the wire from the axle.
6. Raise the stabilizer and secure it.
7. Install the exhaust system from behind, refer to Section Removal and installation of the exhaust system.
8. Reinstall the rear wheel so that the markings made during removal match. Pre-lubricate with a thin layer of bearing grease the centering belt of the wheel disk on the hub. Do not grease wheel bolts. Replace rusty bolts. Wrap bolts. Lower the car onto its wheels.
9. Tighten the collar nut to 250 Nm. To fix the wheel at the same time, ask the assistant to press the brake pedal.
10. Caulk the nut, thus securing it from unscrewing, for which, using a punch, press the collar of the nut into the groove of the drive shaft.
11. Tighten the wheel bolts crosswise to 100 Nm.
12. Fix the stabilizer, for which ensure the empty weight of the car, refer to Section Removal and installation of the rear shock absorber.
