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. Make sure the fuel tank is full, and that the spare tire, the jack, and the tools are in place on the
vehicle.
4. Check the tire size and tire pressure.
5. Check the runout of the wheels and tires (see page 18-9). 6. Check the suspension ball joints (Hold a tire with
your hands, and move it up and down and right and
left to check for movement).
7. Before doing alignment inspections, be sure to remove all extra weight from the vehicle, and no
one should be inside the vehicle (driver or
passengers).
8. Bounce the vehicle up and down several times to stabilize the suspension.
9. Check that the steering column is set at the center tilt and telescopic position.
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. 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.1. Check the camber angle. NOTE: There are two types of rear upper arms. Those that are marked with ‘‘C’’ (A), and those with no
marks. Be sure to use the correct alignment
specifications.
 If the measurement is within specification, measure the toe-in.
 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. The front camber can be adjusted by exchanging one or
both of the damper pinch bolts with a smaller diameter
adjusting bolt. The difference between the adjusting
bolt diameter and the pinch bolt hole diameter allows
for a small range of adjustment.
1. Raise the front of the vehicle, and support it with safety stands in the proper locations (see page
1-11).
2. Remove the front wheels.
3. Loosen the damper pinch bolts (A), 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 damper pinch bolts to the specified torque.
5. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the front wheels.
6. Lower the vehicle to the ground, and bounce the front of the vehicle up and down several times to
stabilize the suspension.

7. Measure the camber angle.
 If the measurement is within specification,measure the toe.
 If the measurement is not within specification, go to step 8.
8. Raise the front of the vehicle, and support it with safety stands in the proper locations (see page
1-11).
9. Remove the front wheels.
10. Replace the damper pinch bolts with the adjusting bolts (A), and adjust the camber angle.
NOTE: Install the washers (B) included adjusting bolt set between the front damper and self-locking nut.
 The camber angle can be adjusted up to 25 ’ (center of tolerance) by replacing one damper
pinch bolt with the adjusting bolt.
 The camber angle can be adjusted up to 50 ’ by replacing both damper pinch bolts with the
adjusting bolts.
11. Tighten the adjusting bolts to the specified torque value.
12. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the front wheels.
13. Lower the vehicle to the ground, and bounce the front of the vehicle up and down several times to
stabilize the suspension.
14. Measure the camber angle. If the camber angle is not within specification, repeat steps 8 through 13
to readjust the camber angle. If the camber
measurement is correct, measure toe-in, and adjust
it if necessary. 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. Set the steering column to the middle tilt and center telescopic positions. Center the steering
wheel spokes, and install a 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 to the specified torque value. Reposition the rack-end
boot if it is twisted or displaced.
5. Go to rear toe inspection/adjustment.

 Ball joint remover, 28 mm 07MAC-SL0A202
Always use a ball joint remover to disconnect a ball
joint. Do not strike the housing or any other part of
the ball joint connection to disconnect it.
1. Install a hex nut (A) or the ball joint thread protector onto the threads of the ball joint (B).
NOTE: Using a hex nut, make sure the nut is flush
with the ball joint pin end to prevent damage to the
threaded end of the ball joint pin.
2. Apply grease to the ball joint remover on the areas shown (A). This will ease the installation of the tool,
and prevent damage to the pressure bolt (B)
threads. 3. Loosen the pressure bolt (A), and install the ball
joint remover as shown. Insert the jaws carefully,
making sure not to damage the ball joint boot.
Adjust the jaw spacing by turning the adjusting bolt
(B).
NOTE: Fasten the safety chain (C) securely to a
suspension arm or the subframe (D). Do not fasten
it to a brake line or wire harness.
4. After adjusting the adjusting bolt, make sure the head of the adjusting bolt is in the position shown
to allow the jaw (E) to pivot.
5. With a wrench, tighten the pressure bolt until the ball joint pin pops loose from the ball joint
connecting hole. If necessary, apply penetrating
type lubricant to loosen the ball joint pin.
NOTE: Do not use pneumatic or electric tools on
the pressure bolt.
6. Remove the ball joint remover, then remove the nut from the end of the ball joint pin, and pull the
ball joint out of the ball joint connecting hole.
Inspect the ball joint boot, and replace it if
damaged.
