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.
Replace.
