- Remove the differential housing cover. For additional information, refer to DIFFERENTIAL HOUSING COVER .
- Install the Dial Indicator Gauge with Holding Fixture and measure the ring gear backlash.
- If a zero backlash condition occurs or the backlash is not within specification, proceed to Step 3.
- If the backlash is within specification, proceed to Step 14.
- Remove the axle shafts. For additional information, refer to AXLE SHAFT .
- Remove the 4 bearing cap bolts and 2 caps.
- If a zero backlash condition has occurred, add 0.50 mm (0.020 in) to the RH side shim and subtract 0.50 mm (0.020 in) from the LH side shim to allow a backlash indication. Install the 2 bearing caps and 4 bolts.
- Tighten to 112 Nm (83 lb-ft).
- Go back to Step 2.
- To correct for high or low backlash, increase the thickness of one differential bearing shim and decrease the thickness of the other differential bearing shim by the same amount. Refer to the following tables when adjusting the backlash.
