6.2.8 Checking clearance between
differential case and differential side gear
1. Measure the differential side gear boss O.D. with an
outside micrometer.

6.2.10 Checking 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 it
with differential side gear shims.
