Driveshaft, Removing And Installing, Driveshaft Bolted On Transmission Side: Installing

WARNING: This page is about a different variant/trim than selected.

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

Remove the old, dry High Temperature Grease from the CV joints and the driveshaft flanges. Insert the same quantity of High Temperature Grease G 052 133 A3.
Always remove any remaining locking fluid from thread bores in drive flanges for transmission driveshaft and for rear final drive. 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).
Pay attention to the installed position of the driveshaft: the center of the CV joint is located behind the intermediate bearing facing the rear final drive.
Check the driveshaft seal on the rear final drive flange and the transmission for damage (bent, rubber layer worn off) and replace if damaged. Replace the damaged seal.

-- Install the driveshaft while paying attention to the rear final drive:
