NOTE:

• To avoid imbalance, the flanges of the drive shaft -arrow A- and of the rear final drive -arrow B- must be installed so that the factory color markings or the markings made subsequently are in line.
• If a new drive shaft is installed and if the factory color marking on the flange of the rear final drive is no longer visible, the radial run-out on the drive shaft flange must be measured. Refer to Drive shaft flange, measuring and marking radial run-out  and the color marking on the drive shaft placed in line with the new marking on the flange.
• Replace gaskets on flange shafts (detach protective foil and stick gasket onto flange shaft).
• Remove the old and dry high-temperature grease from the constant velocity joints and the flanges for the drive shaft. Replace with the exact same quantity of new high-temperature grease G 000 633.
• Note the installation position of the drive shaft: The central constant velocity joint is located behind the center bearing facing toward the rear final drive.
• After removing the drive shaft from the rear final drive, a thick washer that may be located between the shim and the bolt head must not be reinstalled.
• It is essential that the locking fluid remaining in the threads in the flange shafts on the transmission and rear final drive is cleaned out after removing the drive shaft. Otherwise there is a danger that the new bolts will seize when they are screwed in and then shear if they have to removed later.
• The threaded holes can be cleaned with a thread tap.
• Replace drive shaft bolts (self-locking).

• Install drive shaft and attach bolts for constant velocity joint.
