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.

After applying the lubricant, you should wipe any extra grease and dirt from the area with a rag.

The front driveshaft on 4WD models (and the rear half of the driveshaft on models with a two-piece driveshaft) incorporates a slip yoke as part of the shaft. This arrangement allows the driveshaft to alter its length during vehicle operation.
