Make necessary correction or parts replacement if
wear, damage, corrosion or any other abnormal
condition 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
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) When installing the ring gear, apply LOCTITE
271 or equivalent to all the threaded area and
half of the unthreaded area of the bolt.
4) Discard used bolts and install new ones.
