26 11 000 Removing and installing propeller shaft (inserted) completely

Special tools required: 

IMPORTANT: On four-wheel drive vehicles with defective, non-engaging drive, it is imperative that the following information is taken account of. 
IMPORTANT: Replacement of the insert nut on the rear axle final drive is absolutely required!
The insert nut already has a screw locking.
After the propeller shaft has been screwed into the rear axle final drive (insert nut), a hardening time of at least 2 hours  is absolutely necessary.
The hardening time may be extended at lower temperatures!
Failure to comply with these instructions may cause serious damage!

Necessary preliminary tasks: 

IMPORTANT: Adhere without fail to the installation and bolt-tightening sequence.
Installation sequence:
  1. Join propeller shaft to transmission
  2. Join propeller shaft to rear axle final drive
  3. Join center mount

Screw-fastening sequence:
  1. Insert nut
  2. Flexible disc to transmission
  3. Center mount
IMPORTANT: To avoid buzzing sound after refitting the propeller shaft:
  1. 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.
  2. During installation the three-bolt flange (3) must be forced back together again with the flexible disc (2) in the same position.
  3. Replace ZNS bolts and self-locking nuts.

IMPORTANT: The bi-hexagonal flange nut must not be used for bracing. 
Failure to comply with this instruction may result in serious damage to the rear axle final drive.
IMPORTANT: The insert nut must be opened clockwise - see direction of arrow. 
Turning the recessed nut in counter-clockwise direction will automatically tighten the recessed nut further and significantly damage the bi-hexagonal flange nut.
If the insert collar of the flange nut was damaged, the propeller shaft can no longer  be secured using a new insert nut and the rear axle differential must be replaced.
