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.

-- Install the bolts -arrows- just far enough so that the so the intermediate bearing can still be moved.
