  5. Measurement of backlash (Selection of washer)
    1. Install the genuine axle shaft to differential case.

      Part No. 38415AA070 AXLE SHAFT

    2. Measure the gear backlash with ST1 and ST2, and insert ST2 through the access window of the case.

      ST2 498247100 DIAL GAUGE

      NOTE:
      • Measure the backlash by applying a pinion tooth between two bevel gear teeth.
      • Fix bevel pinion gear in place with a screwdriver or similar tool when measuring.

      Standard value: 0.13 - 0.18 mm (0.0051 - 0.0071 in)
