BACKLASH ADJUSTMENT





2. Place the indicator tip of the J39704 on the heel end (1) of the ring gear tooth.
3. Check the backlash at three equally spaced points.

IMPORTANT: The measurement must not vary more than 0.05 mm (0.002 inch) between the points checked.

4. If the backlash needs adjustment, remove the differential case from the housing.

IMPORTANT: The reduction in the shim pack on one side must be equal to the increase in the shim pack on the other side.

5. If the backlash is correct, change the preload on each side by an equal amount.
6. Make a final gear pattern check.
