Clearance between Pinion Shaft and Differential Pinion
1. Measure the pinion shaft O.D.
2. Measure the differential pinion I.D. and calculate the
clearance.
3. If the clearance exceeds the allowable limit, replace faulty
parts.
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.

Turning Torque of Spiral Bevel Pinion Shaft (Pinion Shaft Only)
1. Install the spiral bevel pinion shaft assembly only to the front
axle case.
2. Measure the turning torque of spiral bevel pinion shaft.
3. If the turning torque is not within the factory specifications,
adjust with the lock nut.
A
After turning torque adjustment, be sure to stake the lock
nut.
