REAR WHEEL ALIGNMENT
PRE-INSPECTION
1. Check the tire inflation and bring to the recom-
mended pressure.
2. Inspect the wheel and tire runout.
3. The vehicle must be on level ground and have no
luggage or passenger load.
4. Check that the suspension is correctly adjusted.
5. The difference in height between the left and right
sides from the center of the wheel to the fender
rim should be within 10 mm (0.39 in).
Caution
a) Front and rear wheel alignments should be
checked simultaneously. If adjustment is
made to either the front or rear wheels,
recheck the alignment, particularly toe-in,
on all other wheels.
b) Check and adjust the steering angle trans-
fer shaft after adjusting the rear wheel align-
ment. (Refer to Section 10.)
TOE-IN
Inspection
1. Raise the rear of the vehicle until the wheels clear
the ground.
2. Turn the wheels by hand, mark a line in the center
of each tire tread using a scribing block.
3. Lower the vehicle.
4. Measure the distance between the marked lines
at the front and rear of the wheels.
Toe-in
0 ± 3 mm (0 ±0.12 in) 2WS
3 ± 3 mm (0.12 ±0.12 in) 4WS
Adjustment (2WS)
1. Loosen the adjusting rod lock nuts, then adjust the
toe-in.
2. To increase the toe-in, turn the adjusting rods as
follows:
Right rod — Turn counterclockwise
Left rod — Turn clockwise
To decrease the toe-in, turn the adjusting rods as
follows:
Right rod — Turn clockwise
Left rod — Turn counterclockwise
Caution
a) Both the left and right rods must be adjust-
ed by the same amount.
b) One turn of the adjusting rod (both sides)
changes the toe-in by about 11.6 mm (0.46
in).
3. Tighten the adjusting rod lock nuts to the speci-
fied torque.
Tightening torque:
55—80 N-m (5.6—8.2 m-kg, 41—59 ft-lb)

86U13X-119
Adjustment (4WS)
To adjust the toe-in, loosen the left and right tie-rod
locknuts, and turn the tie-rods by the same amount.
Caution
a) The left and right tie-rods are both right
threaded, so, to increase the toe-in, turn the
right tie-rod toward the front of the vehicle,
and turn the left tie-rod by the same amount
toward the rear.
b) One turn of the tie-rod (both sides) changes
the toe-in by about 7.8 mm (0.31 in).
c) Adjust the toe-in after adjusting the steer-
ing angle.
Tighten the tie-rod locknuts to the specified torque.
Tightening torque: 69—98 N-m
(7—10 m-kg, 51—72 ft-lb)

CAMBER
Preparation
1. Remove the center caps from the wheels.
2. Uncrimp the locknut and remove it.
86U13X-121
Inspection
1. Install the SST to the driveshaft.

2. Measure the camber angle with the caster/cam-
ber gauge.
Camber: -0°30' ± 45' (2WS)
0°00' ± 45' (4WS)
86U13X-123
Front
EAR TURNING ANGLE (4WS)
Place the rear wheels on a turning radius gauge.
Jack up the front of the vehicle.
Start the engine and let it idle.
Caution
If the engine is stopped while the steering
wheel is left turned to one side or the other,
the rear wheels will return to the straight-
ahead direction, and, when the engine is later
started once again, the direction of the rear
wheels will change. Be sure, therefore, to
check to be sure that the wheels are not
touching, or close to, anyone's hands or feet,
or any other object, when the engine is
stopped or started.
Turn the steering wheel fully left and right, and
measure the rear turning angle.
Rear turning angle Inner 5°00' ± 45'
Outer 5°00' ± 45'
If not within specification, adjust the rear turning
angle. (Refer to Section 10)

Condition C
1. Turn the ignition switch ON.
2. Change the AAS switch from NORMAL to SPORT
or from SPORT to NORMAL, and check the out-
put pattern.
