Zero backlash
10. If a zero backlash condition occurs, add a 0.50-mm (0.020-inch) shim to the RH side and subtract 0.50 mm (0.020 inch) from the LH side to
allow backlash indication. Check backlash. Repeat Step 9.
Backlash not within specification
11. To increase or decrease backlash, remove the bearing caps, and install a thicker shim and a thinner shim as shown.

If backlash is not within specification, correct by increasing the thickness of one differential bearing shim and decreasing the thickness on the
other differential bearing shim by the same amount.
