    • Make the necessary corrections by moving shims from one side of the differential case to the other, until the correct backlash adjustment is achieved.

    • Correct for low backlash by moving the ring gear away from the pinion.

    • Correct for high backlash by moving the ring gear toward the pinion.. Use the General Equipment: Dial Indicator
