Driveshaft, Installing

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 000 633.
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).
Check the driveshaft seal on the rear final drive flange and the transmission flange for damage (bent, rubber layer worn off) and replace if damaged. Replace the damaged seal.
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.

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

The dots on the driveshaft -arrow A- and on the rear final drive -arrow B- must line up.
Maximum difference between the markings: 30°.

-- Install the bolts all the way in by hand but do not tighten them.
