WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

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. 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.
