Driveshaft, Removing And Installing From Rear Final Drive: Installing

Install in reverse order of removal. Pay attention to the following:

• Remove the old, dry High Temperature Grease from the CV joint and the driveshaft flange. Insert the same quantity of High Temperature Grease G 000 633.
• The threads in the flange shaft on the rear final drive must be cleaned of locking fluid residue. They can be cleaned with a thread tap. If the threads are not clean, the bolts will break off when they are being installed.
• After removing the driveshaft from the rear final drive, do not install the additional balance washer (thicker washer) that may be between the backing plate and the bolt.
• Always replace the bolts for driveshaft (self-locking bolts).
• Check the driveshaft seal on the rear final drive flange for damage (bent, rubber layer worn off) and replace if damaged. Replace the damaged seal.

-- Position the driveshaft on the rear final drive while paying attention to the installation position:
