WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2015 Audi S4, 2015 Audi A4 Quattro, and 2014 Audi S4. However, it is still accessible from the selected car via links, so may be relevant.

Install the Driveshaft on the Rear Final Drive

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:
