      Standard backlash (reference)
      0.13 to 0.20 mm (0.00512 to 0.00787 in.)
    3. A01SAMR

      Refer to the backlash when selecting a plate washer for the RH side (differential lock coil side).

    4. A01SAV7

      Select a plate washer for the LH side (ring gear side) so that there is no gap between the rear differential case bearing (outer) and differential case.

    5. Using a plastic-faced hammer, install the plate washer to the LH side (ring gear side).

    6. A01SAK0

      Using a dial indicator, adjust the ring gear backlash until it is within the specification.

      Standard backlash
      0.13 to 0.20 mm (0.00512 to 0.00787 in.)

      Tech Tips

      If the backlash is not within the specification, adjust it by either increasing or decreasing the thickness of the plate washers on both sides by an equal amount.

      Note


      • There should be no clearance between the plate washer and case.

      • Make sure that there is ring gear backlash.

  16. ADJUST SIDE BEARING PRELOAD


    1. A01SAOS

      After adjusting the backlash of the differential ring gear, remove the plate washer from the LH side (ring gear side).

    2. A01SEGW

      Using a micrometer, measure the thickness of the plate washer.

    3. Using the backlash as a reference, select a new plate washer that is 0.05 to 0.20 mm (0.00197 to 0.00787 in.) thicker than the removed plate washer and, using a plastic-faced hammer, tap it in so that it fits against the bearing.

      Tech Tips

      Select a plate washer which can be pressed in 2/3 of the full amount with your finger.

    4. A01SAK0

      Recheck the ring gear backlash.

      Standard backlash
      0.13 to 0.20 mm (0.00512 to 0.00787 in.)

      If the backlash is not within the specification, adjust it by either increasing or decreasing the thickness of the washers on both sides by an equal amount.

      Tech Tips

      An approximately 0.02 mm (0.000787 in.) change in each plate washer results in a 0.03 mm (0.00118 in.) change in the backlash.
