4) Adjust the drive pinion and hypoid driven gear
backlash. <Ref. to 5AT-92, ADJUSTMENT, Front
Differential Assembly.>
5) Apply red lead evenly to the surfaces of three or
four teeth on hypoid driven gear. Rotate the drive
pinion in the leftward and rightward for several
times. Remove the oil pump cover, and check the
tooth contact pattern.
If the teeth contact is inappropriate, adjust the
backlash or thickness of the shim. <Ref. to 5AT-92,
ADJUSTMENT, Front Differential Assembly.>
• Correct tooth contact
Check item: Tooth contact surface is slightly
shifted toward the toe side under a no-load con-
dition. (When driving, it moves towards the heel
side.)
• Face contact
Checking item: Backlash is too large.
Contact pattern

height adjusting washer according to the proce-
dures for moving the drive pinion closer to the driv-
en gear.
