Install the pinion gear assembly, removed shim and new
bearing locknut. (!4-13)
Tighten the bearing locknut to the specified torque.

NOTE:
At this time, it is not necessary to stake the bearing locknut.
(!4-13)
Install the removed right side shim and ring gear. (!4-14)
Measure the backlash using the dial gauge, as shown. Take
backlash readings at several places while turning the pinion
gear shaft in each direction and securely holding the ring
gear. If the backlash is not within specification, the shim must
be changed and the backlash should be re-checked until cor-
rect. Refer to the chart at the right for the appropriate shim
thickness.

Standard: 0.05

Adjust the backlash by referring to the chart at the right and
using the thickness of the removed shim as a guide.
