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

• Tightening specifications. Refer to OVERVIEW - DRIVESHAFT, MOUNTED ON TRANSMISSION SIDE  and Figure.

NOTE:

Remove any old, dry high-temperature grease from the CV joint and the driveshaft flange. Insert the same quantity of High Temperature Grease G 052 133 A3.

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.

Replace the self-locking driveshaft 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.

Wipe the splines on the transmission output shaft with a towel before installing the driveshaft. The splines are not lubricated.

-- First mount the driveshaft on the transmission.

• Maximum bend angle: 10°.
• After the driveshaft is inserted approximately 50 mm into the transmission output shaft, turn the driveshaft slightly to make sure that the transmission output shaft splines are meshed into the inner splines of the driveshaft.
• Push the driveshaft all the way onto the splines on the transmission output shaft.

-- Bend the driveshaft on the intermediate bearing all the way without force.

-- Guide the rear driveshaft on the subframe and fuel tank upward.
