(3) Measure the clearance N between the end
of ST2 and the end surface of ST1 by using a
thickness gauge.
NOTE:
Make sure there is no clearance between the case
and ST2.

(4) Obtain the thickness of pinion height adjust-
ing washer to be inserted from the following for-
mula, and replace the temporarily installed
washer with this one.
NOTE:
Adjust it using the 0 — 3 washers.
T = To + N – 0.05 mm (0.0020 in)
(Example of calculation)
To = 0.15 mm (0.0020 in)
N = 0.1 mm (0.0039 in)
T = 0.15 mm (0.0020 in) + 0.1 mm (0.0039 in) –
0.05 mm (0.0020 in) = 0.2 mm (0.0079 in)
Result: Thickness = 0.2 mm (0.0079 in)
Therefore use part number 32295AA370.
3) Install the selected pinion height adjusting wash-
er on drive pinion, and press the rear bearing cone
into position with ST.

4) Insert the drive pinion into the differential carrier,
and install the preselected bearing preload adjust-
ing collar and washer.
5) Set ST and differential carrier to the press and
install the front bearing cone.
ST 399780104 WEIGHT
NOTE:
Set the carrier to the press until the companion
flange is installed.

17) Tighten the bolt of lock plate to specified
torque.
Tightening torque:
25 N·m (2.5 kgf-m, 18.1 ft-lb)
18) Recheck the hypoid driven gear to pinion back-
lash.
Backlash:
0.10 — 0.15 mm (0.0039 — 0.0059 in)
19) Checking and adjusting the tooth contact of hy-
poid driven gear
(1) Apply an even coat of red lead on both sides
of three or four teeth on the hypoid driven gear.
Check the contact pattern after rotating the hy-
poid driven gear several revolutions back and
forth until a definite contact pattern appears on
the hypoid driven gear.
(2) When the contact pattern is not correct, re-
adjust.
NOTE:
Be sure to wipe off the red lead completely after the
adjustment is completed.
•Correct tooth contact
Check item: Tooth contact pattern is slightly
shifted towards the toe side under no-load rota-
tion. (When driving it will move toward the heel
side.)
•Face contact
Check item: Backlash is too large.
Contact pattern
Corrective action: Increase thickness of drive pin-
ion height adjusting washer in order to bring drive
pinion close to hypoid driven gear.

2. CAMBER
•INSPECTION
1) Place the front wheel on the turning radius
gauge. Make sure the ground contact surfaces of
front and rear wheels are at the same height.
2) Set the adapter at the center of wheel, and then
attach the wheel alignment gauge.
3) Measure the camber angle in accordance with
the operation manual for wheel alignment gauge.
•FRONT CAMBER ADJUSTMENT
1) When adjusting the camber, adjust it to the fol-
lowing value.
2) Loosen the two self–locking nuts located at the
lower front section of the strut.
NOTE:
When the adjusting bolt needs to be loosened or
tightened, hold its head with a wrench and turn the
self–locking nut.
3) Turn the camber adjusting bolt so that the cam-
ber is set at specification.
NOTE:
Moving the adjusting bolt by one scale changes the
camber by approximately 0°15′.

4. STEERING ANGLE
•INSPECTION
•ADJUSTMENT
1) Turn the tie-rod to adjust the steering angle of
both inner and outer wheels.
2) Check the toe–in.
NOTE:
Correct the boot if it is twisted.
5. FRONT WHEEL TOE–IN
•INSPECTION
Toe-in:
0±3 mm (0±0.12 in)
1) Set the toe-in gauge in the position at wheel axis
center height behind the right and left front tires.
2) Place a mark at the center of both left and right
tires, and measure distance “A” between the
marks.
3) Move the vehicle forward to rotate the tires 180°.
NOTE:
Be sure to rotate the tires in the forward direction.
4) Measure distance “B” between the left and right
marks. Find toe–in using the following equation:
A – B = Toe–in
•ADJUSTMENT
When adjusting the toe-in, adjust it to the following
value.
Toe-in:
0±2 mm (0±0.08 in)

gles are within specification.
2) Loosen the left and right side steering tie–rod
lock nuts.
3) Turn the left and right tie–rods by equal amounts
until the toe–in is at the specification.
Both the left and right tie–rods are right–hand
threaded. To increase toe–in, turn both tie–rods
clockwise by equal amount (viewing from the inside
of vehicle).
4) Tighten the tie–rod lock nut.
Tightening torque:
