Drive/Propeller Shaft: Service and Repair

Driveshaft








Removal and Installation

1. WARNING: Before servicing a vehicle equipped with a fire suppression system, depower the system by following the procedure in Fire Suppression System. Failure to follow the instructions may result in serious personal injury.

With the vehicle in NEUTRAL, position it on a hoist.
2. Index-mark the rear axle pinion flange and the driveshaft centering socket yoke.





3. Index-mark the transmission extension housing and driveshaft tube.





4. Remove and discard the 4 bolts.
^ To install, tighten to 112 Nm (83 lb-ft).





5. NOTE: The driveshaft centering socket yoke fits tightly on the rear axle pinion flange pilot. Never hammer on the driveshaft or any of its components to disconnect the yoke from the flange. Pry only in the area shown, with a suitable tool, to disconnect the yoke from the flange.

Using a suitable tool as shown, disconnect the driveshaft centering socket yoke from the rear axle pinion flange.





6. NOTE: Align index marks before removing the driveshaft.

Lower the rear end of the driveshaft to clear the rear axle housing. Pull the driveshaft rearward until the driveshaft slip yoke clears the transmission extension housing.
^ Plug the extension housing to prevent fluid loss.

7. NOTE: The driveshaft centering socket yoke fits tightly on the rear axle pinion flange pilot. To make sure that the yoke seats squarely on the flange, tighten the bolts evenly in a cross pattern.

NOTE: Lubricate the slip-yoke spline with long-life grease.

NOTE: If, after installing a new driveshaft, a vibration is encountered, align the factory-made yellow paint mark at the rear of the driveshaft tube with the factory-made yellow paint mark on the rear axle pinion flange. If the paint marks are not visible, refer to driveshaft balancing.

NOTE: Inspect the mating surfaces on the rear axle pinion flange and the driveshaft centering socket yoke for foreign material and for damage from nicks or burrs that could prevent the flanges from fitting tightly together. Repair damaged areas or install new components as necessary to make sure a tight fit is obtained.

To install, reverse the removal procedure.





8. WARNING: If the vehicle is equipped with a fire suppression system, repower the system. For important safety warnings and procedures, refer to Fire Suppression System. Failure to follow these instructions may result in serious personal injury.

Repower the fire suppression system.
