Symptoms:

  • Excess differential/axle backlash
  • Differential side gear thrust washer failure
  • Washers not serviced separately

Cause:

Worn side gear thrust washers allow the gears to move away from pinions, causing backlash and clunk.

Correction:

Hardened thrust washers allow differential salvage and correct setup.
