Removal Procedure
Important: Observe and mark the positions of all the driveline components, relative to the propeller shaft and the axles, prior to
disassembly. These components include the propeller shafts, drive axles, pinion flanges, output shafts, etc. Reassemble all the components
in the exact places in which you removed the parts. Follow any specifications, torque values, and any measurements made prior to
disassembly.
1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle .
2. Remove the tire and wheel assemblies.
3. Remove the rear brake calipers.
4. Reference mark the rear propeller shaft (3) to the rear axle pinion yoke (4).
5. Disconnect the propeller shaft from the axle.
Wrap the bearing caps with tape in order to prevent the loss of bearing rollers.
Support the propeller shaft as necessary.
6. Measure the amount of torque required to rotate the pinion. Use an inch-pound torque wrench. Record this measurement for reassembly. This will
give the combined preload for the following components:
*
The pinion bearings
*
The pinion oil seal
*
The differential case bearings
*
The axle bearings
*
The axle seals
