E: INSPECTION
Wash all the disassembled parts clean, and exam-
ine them for wear, damage and other defects. Re-
pair or replace the defective parts as necessary.
1) Hypoid driven gear and drive pinion
• If there is evidently an abnormal tooth contact,
find out the cause and adjust until the teeth contact
correctly. Replace the gear if there is an excessive
worn or an incapable adjustment.
• If crack, cutout or seizure is found, replace the
parts as a set. Slight damage of some teeth can be
corrected by oil stone or the like.
2) Side gear and pinion mate gear
• Replace if cracks, scoring or other defects are
evident on the tooth surface.
• Replace if thrust washer contact surface is worn

or seized. Slight damages of the surface can be
corrected by oil stones or equivalent.
3) Bearing
Replace if seizure, peeling, wear, rust, dragging
during rotation, abnormal noise or other defect is
evident.
4) Thrust washer of the side gear and pinion mate
gear:
Replace if seized, flawed, abnormally worn or hav-
ing other defects.
