Removal Procedure

Important:  Observe and accurately reference mark all driveline components relative to the propeller shaft ad axles before disassembly. These components include the propeller shaft, the drive axles, the pinion flanges, the output shafts, etc. All components must be reassembled in the exact relationship to each other as they were when removed. In addition, published specifications and torque values, as well as any measurements made prior to disassembly must be followed.

1. Raise the vehicle. Refer to LIFTING & JACKING THE VEHICLE in General Information.
2. Reference mark the rear propeller shaft to the pinion flange/yoke and to the front propeller shaft, then reference mark the front shaft to the transmission or the transfer case.
3. Remove the center bearing support bracket from the crossmember.

4. Remove the bolts and/or the yoke retainers from the rear axle pinion flange/yoke as necessary.
5. Remove the rear propeller shaft with the center bearing by sliding the propeller shaft from the spline shaft.
6. Remove the propeller shaft from the rear of the transmission or the transfer case.
7. Clean the mating surfaces bearing caps, bearing straps and pinion yoke of corrosion using crocus cloth or 400 grit sandpaper.
8. Clean all parts with an approved solvent.
9. Inspect the outer surface of the front slip yoke for burrs. Burring damages the transmission seal.
10. Inspect the slip yoke splines for wear.
11. Inspect for proper installation and uniform seating of the bearing cups.
12. Inspect for twisted slip yoke splines or the wrong universal joint.
