Version With Rear Constant-Velocity Joint
Remove Propeller Shaft -Version With Rear Constant-Velocity Joint-
Remove complete exhaust system.
Remove heat shield (1).
Remove bracket (1 and 2) for exhaust suspension.
Remove bar (3).
Installation:
Install bar (3) with long collar (4) towards front.
Version with joint disk, front:
Remove flexible disk from transmission.
Installation:
Replace stop nuts.
Only tighten screw connection by way of nut.
To prevent subjecting flexible disk to torsion stress, turn nuts/screws on flange side.
Remove constant-velocity joint from final drive.
Remove center bearing.
Tightening torque,Center mount = 21 Nm.
Installation:
Pretension center bearing in direction of travel 2 ... 4 mm (A).
Caution: Do not let propeller shaft fall into joints. In particular, on constant velocity joint, rubber collar can become squashed, or joints may be damaged.
Pull propeller shaft downwards at center bearing and in so doing detach from centering pin on manual transmission or constant velocity joint from final drive.
Note: Protect constant velocity joint with transportation cap against contamination.
Installation:
Top up grease fill.
Grease.
Refer to BMW Parts Service.
Quantity of grease. Refer to Technical Data.
Withdraw constant-velocity joint (1) up to stop.
Degrease sealing surfaces on constant velocity joint and drive flange.
Replace gasket (2).
Installation:
Use new nuts.
Attach propeller shaft with pulled-apart constant-velocity joint to drive flange of final drive.
Caution: The constant-velocity joint must not be compressed during assembly because the grease fill can force away the sealing ring, leading to leakage from the constant-velocity joint.
By alternately tightening 2 opposing nuts, draw constant-velocity joint uniformly into drive flange.
Then tighten down the remaining nuts.
Installation:
Check centering mount (4).
Replace damaged centering mount.
Coat centering mount with Molykote Longterm 2 grease.
