After raising the vehicle, you should clean the grease fitting on the front driveshaft with a rag.

To install the driveshaft, remove the plastic bag from the transmission or transfer case extension housing and wipe the area clean. Inspect the oil seal and center support bearing. Insert the front end of the driveshaft assembly into the transmission or transfer case extension housing. Raise the rear of the driveshaft into position, checking the alignment marks. If it's a two-piece unit, raise the center support bearing and bolt it loosely into place. Raise the rear end of the rear shaft into position and make sure the alignment marks are in alignment. Remove the tape securing the bearing caps and install the clamps and fasteners.

The manufacturer recommends replacing driveshaft fasteners with new ones.

An oil seal prevents fluid from leaking out of the extension housing and keeps dirt from entering the transmission or transfer case. If leakage is evident at the front of the driveshaft, the extension housing oil seal should be replaced.

A conventional grease gun should be used to apply sufficient lubricant to the fitting.

Factory U-joints are lubricated for life and must be replaced if problems develop.
