ferential intermediate case, measure the pinion's back-
lash with a dial indicator.
Standard backlash:
0.05 - 0.20 mm (0.0020 - 0.0079 in.)
If the backlash is not within the specified value, refer to the table
below and select a thrust washer which will ensure that the
backlash is within the specified value.
