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.
Factory spec.

Backlash between Differential Pinon 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.

(Reference)
• Thickness of adjusting shims :
0.4 mm (0.016 in.) 1.0 mm (0.039 in.)
0.6 mm (0.024 in.) 1.2 mm (0.047 in.)
0.8 mm (0.031 in.)
• Tooth contact : More than 35 %
• Center of tooth contact :
1/3 to 1/2 of the entire width from the small end.
Turning Force 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.
If the turning torque is not able to adjust by lock nut (2), change
the thickness of collar (1) and adjust with lock nut (2) again.
(Reference)
• Standard size of collar (1) : 10.0 mm (0.349 in.) of thickness
