  2. Measure the backlash between the differential bevel gear and differential bevel pinion. Adjust the backlash if not within specified limit. Refer to MANUAL TRANSMISSION AND DIFFERENTIAL(6MT) (TY75)>FRONT DIFFERENTIAL ASSEMBLY>INSPECTION>DIFFERENTIAL BEVEL PINION GEAR BACKLASH .
    NOTE: Be sure the differential bevel pinion gear teeth contact adjacent gear teeth during measurement.

  3. Align the pinion shaft pin hole with the differential case pin hole, and drive the straight pin into the holes from the hypoid driven gear side using the ST.
    NOTE: Use a new straight pin. After driving, crimp the area around the hole, and make sure that the straight pin will not come out.
