Backlash Shim Adjustment
38. Push and hold ring gear downward while not allowing the pinion gear to rotate. Dial indicator reading should be between 0.12 mm (0.005 inch)
and 0.20 mm (0.008 inch). If backlash is not within specifications transfer the necessary amount of shim thickness from one side of the axle
housing to the other.
39. Verify differential case and ring gear runout by measuring ring to pinion gear backlash at several locations around the ring gear. Readings should
not vary more than 0.05 mm (0.002 inch). If readings vary more than specified, the ring gear or the differential case is defective.
After the proper backlash is achieved, perform Gear Contact Pattern Analysis procedure.
