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:

D

Ring gear, pinion gear

D

Bearing

D

Side gear, pinion mate gear, differential shaft

D

Differential cage, carrier

D

Thrust washer

D

Oil seal

Ring gear replacement:

1. The ring gear should always be replaced with the

drive pinion as a set.

2. Clean the ring gear threaded holes to remove the

locking agent.

3. Discard used bolts and install new ones.
4. When installing the ring gear, apply LOCTITE 271 or

equivalent to all the threaded area and half of the
unthreaded area of the bolt.
