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 abnormal tooth contact is evident, find out the
cause and adjust to give correct tooth contact. Re-
place the gear if excessively worn or incapable of
adjustment.
• If crack, score or seizure is evident, replace as a
set. Slight damage of tooth can be corrected by oil
(A)
stone or the like.
2) Side gear and pinion mate gear
• Replace if crack, score or other defects are evi-
dent on tooth surface.
• Replace if thrust washer contacting surface is
worn or seized. Slight damage of the surface can
