The driveshaft is a tube running between the transfer case or transmission and the rear axle or front axle. Universal joints are located at either end of the driveshaft(s) and permit power to be transmitted to the rear (and, on 4WD models, the front) wheels at varying angles. On long wheelbase models, the driveshaft is actually two shafts connected by a universal joint and supported in the middle by a bearing attached to the frame.

If leakage is evident, the oil seal should be replaced.

Installation is the reverse of removal with the following additions: a) Lubricate the slip yoke splines with chassis grease. b) Inspect the housing seal for damage and replace it if necessary. c) Do not allow the driveshaft slip yoke to bottom out on the output shaft. d) Ensure that the center bearing bracket is aligned at right angles or "square" with the driveshaft. If there were spacers under the bracket, install them again. e) Line up the paint marks on the rear yoke and the rear axle companion flange. f) Tighten all fasteners to the torques.

Removal of the drive shafts and drive axle.

Look for the yellow paint marks made at the factory. If these aren't visible, use a scribe or white paint to place marks on the driveshaft and the differential flange in line with each other.
