Installing
Install in reverse sequence; note the following points
Note. To prevent imbalance, the flanges on the driveshaft (arrow -A-) and on the rear final drive (arrow -B-) must be installed so that the factory markings (or the markings made on removal) are in alignment. If a new driveshaft is being installed and the factory marking on the rear final drive flange is no longer visible, the radial run-out at the flange on the rear final drive must be measured. Refer to Measuring and marking radial run-out at driveshaft flange on rear final drive , and the paint marking on the driveshaft must be aligned with the new marking on the flange. Replace gaskets on flange shafts (pull off backing foil and stick gasket onto flange). Remove old, dried-out high-temperature grease from constant velocity joints and driveshaft flanges. Put in exactly the same quantity of fresh high-temperature grease G 000 633. After removing the driveshaft from the rear final drive, the balance disc (thick washer) that may be installed between the lock plate and the socket head bolt must not be re-installed. After removing the driveshaft, it is important to clean any remaining locking compound out of the threads in the flange shafts on the driveshaft and rear final drive. If this is not done the new bolts can seize when they are threaded in and shear off later if they have to be removed. The threaded holes can be cleaned with a thread tap. Replace driveshaft bolts (self-locking).
