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

Backlash between Differential Pinion Gear and Differential
Side Gear
1. Stick a strip of plastigauge the three spots on the differential
pinion gear (2) with grease.
2. Reassemble the differential gear assembly.
3. Fix the differential gear assembly, and install the drive shaft (5).
4. Turn the drive shaft (5).
5. Remove the differential pinion gear (2) from the differential gear
assembly, and measure the thickness of the plastigauge with an
outside micrometer.
6. If the backlash is not within the factory specifications, adjust with
shims (4), (6).
