Installation is the reverse of the removal steps with the following additions: a) On 2WD models, slide the front of the driveshaft into the transmission. b) On 4WD models, position the front end of the driveshaft on the transfer case with the alignment marks lined up. c) Raise the rear of the driveshaft into position, checking to ensure the marks are in alignment. If not, make sure the transmission is still in Neutral, then turn the rear wheels to match the pinion flange and the driveshaft. d) On 2011 models, tighten the driveshaft-to-axle bolts in a crisscross pattern, to the torque.

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.

Removal of the drive shafts and drive axle.

An oil seal is used to prevent leakage of fluid and to keep dirt and contaminants from entering the transmission.

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.
