6. INSPECT DIFFERENTIAL PINION AND SIDE GEAR BACKLASH
a. Using a dial gauge, check the backlash of the side gear while holding 1 pinion gear toward the differential case.
Backlash: 0.05 to 0.20 mm (0.0020 to 0.0079 inch)
If the backlash is not within the specification, install the 2 side gear thrust washers of differential thickness.
HINT: Measure the backlash of the side gear with the side gear shaft installed.
