Inspection and Repair
Make necessary correction or parts replacement if
wear, damage, corrosion or any other abnormal
conditions are found through inspection.
Check the following parts:
Ring gear, pinion gear
Bearing
Side gear, pinion gear, cross pin
Differential cage, carrier
Thrust washer
Oil seal
Clearance between pinion gear and cross pin:
mm(in)
Standard Limit
0.06 - 0.12

Check the ring gear the side gear fitting faces and the
cross pin hole for scores or roughness. Correct as
necessary. Slight scores or roughness may be
corrected with an oil stone or fine sand paper.

Ring gear replacement:
1. The ring gear should always be replaced with the
drive pinion as a set.
2. Discard use bolts and install new ones.
3.
Apply LOCTITE 271 on bolt from the end of thread
to the middle of straight portion.
4. Tighten the fixing bolts in a diagonal sequence as
illustrated.

cage.
2. Install the pinion gear by engaging it with the side
gears while turning both pinion gears
simultaneously in the same direction.

3. Install cross pin.
Be sure to install the cross pin so that it is in
alignment with the lock pin hole in the
differential cage.

4. Check the amount of backlash.
Backlash between the side gear and the pinion
gear. mm (in)
