5) Remove the drive pinion shaft assembly, and
then check tooth contact. If tooth contact is inaccu-
rate, adjust it. <Ref. to 6MT-99, ADJUSTMENT,
Drive Pinion Shaft Assembly.>
• Correct tooth contact
NOTE:
Under no load, tooth contacts 50 — 60% from cen-
ter to toe side (tooth contact shifts to heel side
when driving).

1. BEVEL PINION GEAR BACKLASH
1) Measure the bevel pinion gear backlash. <Ref.
to 6MT-107, BEVEL PINION GEAR BACKLASH,
INSPECTION, Front Differential Assembly.>
2) Disassemble the differential case. <Ref. to 6MT-
104, DIFFERENTIAL CASE, DISASSEMBLY,
Front Differential Assembly.>
3) Select a washer from the following table, and
then assemble the differential case. <Ref. to 6MT-
106, DIFFERENTIAL CASE, ASSEMBLY, Front
Differential Assembly.>

2. HYPOID GEAR BACKLASH
1) Install the side retainers of RH and LH side.
ST1 499787000
ST2 18630AA000 WRENCH ASSY (LH SIDE)
NOTE:
Screw in the side retainer of RH side a bit further
than LH side.
2) Install the drive pinion shaft assembly, and then
secure with four bolts.
NOTE:
Use the old gasket and washer to prevent the mat-
ing surface of housing from damaging.
Tightening torque:
⋅
50 N m (5.1 kgf-m, 36.9 ft-lb)
3) Using the ST, screw in the side retainer LH until
the drive pinion and hypoid driven gear contacts
lightly. Loosen the side retainer RH.

4) Using the ST, rotate the drive pinion shaft sever-
al times.

5) Repeat step 3) and 4) until the side retainer LH
can not be rotated. For the side retainer RH, screw
in until the inner race and outer race contacts light-
ly. This is "0" backlash condition.
