Clearance between Differential Case and Differential Side Gear
1. Measure the differential side gear boss O.D. with an outside
micrometer.
2. Measure the differential case I.D. with a cylinder gauge and
calculate the clearance.
3. If the clearance exceeds the allowable limit, replace faulty parts.

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

Backlash between Differential Pinion and Differential Side Gear
1. Secure the differential case with a vise.
2. Set the dial indicator (lever type) with its finger on the tooth of the
differential side gear.
3. Press differential pinion and side gear against the differential
case.
4. Hold the differential pinion and move the differential side gear to
measure the backlash.
5. If the backlash exceeds the allowable limit, adjust with differential
side gear shims.
