2. Wheel Alignment
A: INSPECTION
Check the following items before performing the wheel alignment measurement.
Check items before measuring wheel alignment:
•Tire inflation pressure
•Uneven wear of RH and LH tires, or difference of sizes
•Tire runout
•Excessive play and wear of ball joint
•Excessive play and wear of tie rod end
•Excessive play of wheel bearing
•Right and left wheel base imbalance
•Deformation and excessive play of steering link
•Deformation and excessive play of suspension parts
Check, adjust and measure the wheel alignment in accordance with the procedures indicated in the figure.

1. WHEEL ARCH HEIGHT
1) Park the vehicle on a level surface.
2) Empty the vehicle so that it is at “curb weight”. (Empty the luggage compartment, load the spare tire, jack
and service tools, and fill up the fuel tank.)
3) Set the steering wheel in a straight–ahead position, and stabilize the suspension by moving the vehicle in
a straight line for more than 5 m (16 ft).
4) Suspend a thread from the wheel arch (point “A” in the figure below) and affix at a position directly above
the center of wheel.
5) Measure the distance between the point “A” and the center of wheel.

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′.

•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 caster angle in accordance with the
operation manual for wheel alignment gauge.
To i n c r e a s e c a m b e r :
Rotate the left side counterclockwise. Rotate the right side clockwise.
To d e c r e a s e c a m b e r :
Rotate the left side clockwise. Rotate the right side counterclockwise.

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)
1) Check that the left and right wheel steering an-
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:
85 N·m (8.7 kgf-m, 62.7 ft-lb)
NOTE:
Check and correct the tie rod boot if twisted.
6. REAR WHEEL TOE–IN
•INSPECTION
Toe-in:
2±2 mm (0.08±0.08 in)
Refer to FRONT WHEEL TOE–IN for rear toe–in
inspection procedures.
