Perform the following before disassembling the axle:

1. Remove the drain plug from the axle.
2. Drain the axle lubricant.
3. Inspect the oil and the case for metal chips.

Determine the source of the metal chips, such as a broken gear or bearing cage.

4. Measure the rotating torque of the drive pinion and differential case assembly using an inch-pound torque wrench. Record the measurement.
5. Check the ring gear backlash. Refer to Backlash Inspection and Adjustment .

This information can be used in order to determine the cause of the axle problem. The information will also help when setting up and preloading the differential case.

Determine the cause of the axle problem before disassembly, if possible.
