Driveshaft, Installing
Install in reverse order of removal. Note the following:
- Remove the old, dry High Temperature Grease from the CV joints and the driveshaft flanges. Fill with the exact same amount of new High Temperature Grease.
- 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:
- The dots on the driveshaft -arrow A- and on the rear final drive -arrow B- must line up.
- Maximum difference between the markings: 30º.
- Install the new 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.
- Tighten the bolts -1- on the rear driveshaft. Follow the tightening sequence. Refer to → Fig. "Driveshaft to Rear Final Drive - Tightening Specification and Sequence".
- Tighten the bolts on the front driveshaft. Tightening specification. Refer to -item 5-.

- Tighten the heat shield -A- to the transmission -arrows-. Tightening Specification. Refer to → Fig. "Driveshaft Heat Shield - Tightening Specification".
- Install the heat shield -1-.
- If equipped, install the front crossmember -2- and the rear crossmember -3-. Refer to → Body Exterior; Rep. Gr.66; Underbody Panel; Overview - Underbody Panels.
