1. CAUTION: The electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the rear jack storage area. Failure to do so can result in the unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these operations. Failure to follow these instructions may result in personal injury.

With the vehicle in NEUTRAL, position it on a hoist.

Installation

4WD vehicles





1. Align all the index marks and install the driveshaft slip yoke into the transmission extension housing.





2. CAUTION: The driveshaft flange fits tightly on the pinion flange pilot. To make sure that the driveshaft flange seat squarely on the pinion flange pilot, tighten the driveshaft flange bolts evenly in a cross pattern.

CAUTION: If new driveshaft flange bolts are not available, coat the threads of the original driveshaft flange bolts with Threadlock and Sealer.

Align the index marks and install the driveshaft flange and the driveshaft flange bolts.
^ Tighten to 112 Nm (83 ft. lbs.).
