FRONT WHEEL ALIGNMENT
86U13X-108
69G10X-031
Pre-inspection
1. Check the tire inflation and bring to the recom-
mended pressure.
2. Inspect the front wheel bearing play and correct,
it if necessary.
3. Inspect the wheel and tire runout.
4. Inspect the ball joints and steering linkage for any
excessive looseness.
5. The vehicle must be on level ground and have no
luggage or passenger load.
6. The difference in height between the left and right
sides from the center of the wheel to the fender
brim must be within 10 mm (0.39 in).
Caution
a) Front and rear wheel alignment 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 front wheel
alignment. (Refer to Section 10)
TOE-IN
Inspection
1. Raise the front 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. Place the front wheels in the straight-ahead posi-
tion and lower the vehicle.
4. Measure the distance between the lines at the front
and rear of the wheels.
Both measurements must be taken at equal
distances from the ground.
Toe-in (distance greater at rear than front):
3 ± 3 mm (0.12 ± 0.12 in)
Adjustment
To adjust the toe-in, loosen the left and right tie-rod
lock nuts, then 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 7.2 mm (0.28 in).
c) Tighten the tie-rod locknuts to the specified
torque.
Tightening torque: 69—98 N-m

CAMBER AND CASTER
Inspection
The camber and caster is measured by placing the
front wheels on a turning-radius gauge in accordance
with the manufacturer's instructions.
Proceed in the following order:
1. Jack up the vehicle and remove the wheel caps
and nuts. Then attach the SST to the wheel hub
as shown in the figure.
2. Attach the caster/camber gauge to the adapter
and measure the camber and caster.
Camber angle: 0°17' ± 45'
Caster angle: 1°13' ± 45'
Left/right difference:
Camber: 30' max.
Caster: 40' max.
Adjustment
1. Jack up the front of the vehicle and support it with
safety stands.
2. Remove the mounting block nuts.
3. Push the mounting block downward, and turn it
to the desired position.
4. Retighten the nuts to the specified torque.
Tightening torque: 46—63 N-m
(4.7—6.4 m-kg, 34—46 ft-lb)

Steering Angle (turning angle to left and right)
Inspection
The steering angle is measured by placing the front
wheels on a turning-radius gauge.

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)

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)

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)
