Steering Wheel Rotational Play
Check
Power Assist Check
1. Turn the front wheels to the straight ahead position.
2. Measure how far you can turn the steering wheel
left and right without moving the front wheels.
 If the play is within the limit, the steering gearbox and steering linkage are OK.
 If the play exceeds the limit, adjust the rack guide (see page 17-15). If the play is still excessive after
rack guide adjustment, inspect the steering
linkage and steering gearbox (see page 17-5). NOTE: This test should be done with original equipment
tires and wheels at the correct tire pressure.
1. Start the engine, and let it idle.
2. Attach a commercially available spring scale to the steering wheel. With the engine idling and the
vehicle on a clean, dry floor, pull the scale as
shown, and read it as soon as the tires begin to turn.
3. Ifthescalereadsnomorethan34N(3.5kgf,7.7lbf), the power assist is OK. If it reads more, check these
items:
 Steering linkage (see page 17-5)
 Rack guide adjustment (see page 17-15)
 EPS system (see page 17-19)

gearbox.
NOTE: If more than 5 minutes has passed after
applying the sealant, remove the old sealant and
residue, and reapply new sealant. 4. Tighten the rack guide screw (A) to 25 N·m
(2.5 kgf·m, 18 lbf·ft), then loosen it.
5. Retighten the rack guide screw to 3.9 N·m (0.4 kgf·m, 2.9 lbf·ft), then back it off to the specified
angle.
6. Hold the rack guide screw stationary with a wrench, and tighten the locknut (B) by hand until it’s fully
seated.
7. Install the locknut wrench on the locknut, and hold the rack guide screw stationary with a wrench.
Tighten the locknut to the specified torque.
8. Check for unusual steering effort through the complete turning range.
9. Check the steering wheel rotational play (see page 17-4) and the power assist (see page 17-4).

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.

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.
