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 Vehicle Lifting.
2. Drain the axle lubricant. Refer to Rear Axle Lubricant Replacement (8.6 Inch Axle) Rear Axle Lubricant Replacement (9.5 LD Axle) Rear Axle
Lubricant Replacement (9.5 Inch HD and 10.5 Inch Axles).
3. Remove the axle shafts.
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 and the ring gear. 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 pilot bearing
