following:
Note: - Unscrew securing bolts -B- and -C- of rear cross member on rear final
drive.
- Lower final drive on transmission jack.
Always replace self-locking nuts.It is essential to clean out the locking fluid remaining in the threads in
the drive flange on the rear final drive after removing the driveshaft.
Otherwise there is a danger that the new bolts will seize when they
are screwed in and then shear if they have to be removed later. The threaded holes can be cleaned with a thread tap.Replace gasket between driveshaft and drive flange (pull off backing
foil and stick gasket onto drive flange). Surface must be free of
grease. Replace driveshaft bolts (self-locking).
