Backlash between Differential Pinion and Differential Side
Gear
1. Set a dial gauge (lever type) on a tooth of the differential pinion.
2. Fix the differential side gear and move the differential pinion to
measure the backlash.
3. If the measurement exceeds the factory specifications, adjust
with the differential side gears shims and differential pinion gear
shims.

Turning Force of Spiral Bevel Pinion Shaft (Pinion Shaft Only)
1. Clamp the spiral bevel pinion shaft assembly to the vise and
tighten the staking nut.
2. Measure the turning torque of bevel pinion shaft.
3. If the turning force is not within the factory specifications, adjust
with the lock nut.
NOTE
• After turning torque adjustment, be sure to stake the lock
nut.
