Inspection and Repair
Make all necessary adjustments, repairs, and part replacements if wear, damage, or other problems are discovered
during inspection.
• Ring gear, pinion gear
• Bearing
• Side gear, pinion gear, cross pin
• Differential cage, carrier
• Thrust washer
• Oil seal
Visual Check
Inspect the following parts for wear, damage, or other
abnormal conditions.
Ring Gear Replacement
(1) The ring gear should always be replaced with the drive pinion as a set.
(2) W hen installing the ring gear, apply LOCTITE 271 o
r
equivalent to the threaded hole and bolt.
(3) Tighten the fixing bolts in a diagonal sequence as illustrated.
(4) Discard used bolts and install new ones.
