26 11 000 Removing And Installing Complete Propeller Shaft (Constant-Velocity Joint)
Necessary preliminary tasks:
- Remove rear underbody protection.
- Remove complete EXHAUST SYSTEM .
Remove heat shields (1) and (2).
- The flexible disc connection (1) on the front at the propeller shaft must be marked in one plane with the flexible disc (2) and the three-bolt flange (3) before removal.
- During installation the three-bolt flange (3) must be forced back together again with the flexible disc (2) in the same position.
- Replace ZNS bolts and self-locking nuts.
Release screws.
Installation note: ZNS bolts and nuts must be replaced. Replace self-locking nuts.
Important! M57 only: The bolt without washer may only be tightened by means of the nut. The bolt with rolled-on washer which has ribbed teeth facing the support side must be tightened by means of the bolt. Observe different tightening torques. Tightening torque, 26 11 1AZ.
Release bolts and replace.
Using a screwdriver, press constant velocity joint off drive flange at dismantling grooves.
Important! Do not let propeller shaft fall into joints. Joints and rubber cup can be damaged on constant velocity joint.
Grip propeller shaft at center mount and release screws. Tightening torque, 26 11 6AZ
Bend propeller shaft downwards at center bearing. Remove propeller shaft from transmission output flange and detach constant velocity joint from rear axle final drive.
Installation note: Withdraw constant velocity joint (1) up to limit position. Fit shims. Attach propeller shaft with pulled-apart constant velocity joint to drive flange of rear axle final drive.
Alternately tighten 2 opposing screws to draw constant-velocity joint evenly into the input flange. Replace ZNS bolts. Tightening torque, 26 11 4AZ.
Installation:
Check centering mount (4).
Replace damaged centering mount.
Grease centering mount.
Grease.
Refer to OPERATING FLUIDS - DRIVE SHAFT .
