Adjustment of the Differential
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If it is necessary to replace the left side locking differential side gear cam unit and clutch disc assembly, the right side locking differential side gear and clutch disc assembly, or the thrust block, the entire differential must be adjusted. The differential is adjusted using selective thickness thrust washers between the clutch disc assemblies and the case and/or different selective thickness thrust blocks. When adjusting the differential, note the following:
- Assemble the clutch disc assemblies properly.
- Adjust the backlash and thrust block clearance in the following order:
- The left side gear backlash
- The right side gear backlash
- The thrust block clearance
NOTE:
Proper clearance between parts is critical to the operation of the unit.
