Wheel Alignment
The suspension can be adjusted for front camber, front
toe, and rear toe. However, each of these adjustments
are related to each other. For example, when you adjust
camber, the toe will change. Therefore, you must adjust
the front wheel alignment whenever you adjust camber
or toe.
For proper inspection and adjustment of the wheel
alignment, do these checks:
1. Release the parking brake to avoid an incorrect
measurement.
2. Make sure the suspension is not modified.
3. Check the tire size and tire pressure.
4. Check the runout of the wheels and tires (see page
18-9).
5. Check the suspension ball joints. (Hold a wheel
with your hands, and move it up and down and
right and left to check for wobbling.)
6. Bounce the vehicle up and down several times to
stabilize the suspension.
Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
Check the caster angle.
• If the measurement is within specifications, measure
the camber angle.
• If the measurement is not within specifications, check
for bent or damaged suspension components.

Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
Check the camber angle.
• If the measurement for the front camber is outside
the specification, go to front camber adjustment.
• If the measurement for the rear camber is outside the
specification, check for bent or damaged suspension
components.
1. Raise the front of the vehicle, and support it with
safety stands in the proper locations (see page
1-10).
2. Remove the front wheels.
3. Loosen the flange nuts (A) and bolts, and adjust the
camber angle by moving the bottom of the damper
within the range of the damper pinch bolt free play.
4. Tighten the flange nuts to the specified torque.
5. Reinstall the front wheels. Lower the front of the
vehicle to the ground, and bounce the front of the
vehicle up and down several times to stabilize the
suspension.
6. Measure the camber angle.
• If the measurement is within specification,
measure the toe-in.
• If the measurement is not within specification,
check for bent or damaged suspension
components.

Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
NOTE: After setting the front toe always perform the
steering angle sensor writing procedure (see page
19-92).
1. Center the steering wheel spokes and install a
commercially available steering wheel holder tool.
2. Check the toe with the wheels pointed straight
ahead.
• If adjustment is required, go to step 3.
• If no adjustment is required, go to rear toe
inspection/adjustment.
3. Loosen the tie-rod locknuts (A) while holding the
flat surface sections (B) of the tie-rod end with a
wrench, and turn both tie-rods (C) until the front toe
is within specifications.
4. After adjusting, tighten the tie-rod locknuts.
Reposition the rack-end boot if it is twisted or
displaced.
5. Go to rear toe inspection/adjustment.
NOTE: After adjusting the front toe always perform
the steering angle sensor writing procedure
(see page 19-92).
Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
1. Release the parking brake to avoid an incorrect
measurement.
2. Check the toe.
• If adjustment is required, go to step 3.
• If no adjustment is required, remove the
alignment equipment.
3. Hold the adjusting bolt (A) on the lower arm B, and
remove the self-locking nut (C).
4. Replace the self-locking nut with a new one, and
lightly tighten it.
NOTE:
• Always use a new self-locking nut whenever it
has been loosened.
• Reassemble the adjust bolt and cam-plate with
the eccentric facing up.
5. Adjust the rear toe by turning the adjusting bolt
until the toe is correct.
6. Tighten the new self-locking nut while holding the
adjusting bolt.

Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
1. Turn the wheel right and left while applying the
brake, and measure the turning angle of both
wheels.
2. If the turning angle is not within the specifications,
check for bent or damaged suspension
components.
1. Raise the vehicle, and support it with safety stands
in the proper locations (see page 1-10).
2. Remove the wheels.
3. Install suitable flat washers (A) and the wheel nuts.
Tighten the nuts to the specified torque to hold the
brake disc securely against the hub.
4. Attach the dial gauge. Place the dial gauge against
the hub flange.
5. Measure the bearing end play by moving the disc
inward and outward.
6. If the bearing end play measurement is more than
the standard, replace the wheel bearing.
