Note:
^
General repair instructions.
^
Drive shaft may be bent without force up to stop of the central constant velocity joint. Further bending may cause damage to the joint or to the
boots.
^
Only store and transport drive shaft extended.
^
No repair work can be carried out on the drive shaft with the exception of removing, installing and adjusting.
^
If the drive shaft is only detached at the transmission or from rear final drive then the drive shaft is to be tied-up at the constant velocity joint. The
drive shaft may also be bent without force up to the stop of the central constant velocity joint, if necessary.
^
Prior to removal mark the position of all parts in relation to each other. Reinstall in the same positions otherwise the imbalance will be excessive;
the bearings could be damaged and humming noises may occur.
^
After removing the drive shaft from the rear final drive, a thick washer that may be located between the shim and the hexagon socket head bolt
must not be reinstalled.
^
If complaints are received (noises, vibrations), it is essential to check the radial run-out to drive flange at the rear final drive. A correct adjustment
may repair the problem.
