Wheel Alignment
A: INSPECTIONCheck the following items before taking wheel alignment measurement.
Check items before taking wheel alignment measurement:
^ tire air pressure
^ unbalanced right and left tire wear, size difference
^ tire run-out
^ ball joint excessive play, wear
^ tie rod end excessive play, wear
^ wheel bearing excessive play
^ right and left wheel base imbalance
^ steering link part deformed, excessive play
^ suspension part deformed, excessive play
Check, adjust and/or measure wheel alignment in accordance with procedures indicated in figure.
1. WHEEL ARCH HEIGHT
1) Set vehicle on a level surface.
2) Adjust tire pressure to specifications.
3) Set vehicle under "curb weight" conditions. (Empty luggage compartment, install spare tire, jack, service tools, and top up fuel tank.)
4) Set steering wheel in a straight line, then move the vehicle straight ahead more than 5 m (16 ft) to settle the suspension.

5) Suspend thread from wheel arch (point "A" in figure) to determine a point directly above center of wheel.
6) Measure distance between measuring point "A" and center of wheel.
2.CAMBER
Inspection
1) Place front wheel on turning radius gauge. Make sure ground contacting surfaces of front and rear wheels are set at the same height.
2) Set ST into the center of the wheel, and then install the wheel alignment gauge. ST 927380002 ADAPTER
3) Follow the operation manual for wheel alignment gauge to measure the camber angle.
NOTE: Refer to the "SPECIFICATIONS" for the camber values.
Front Camber Adjustment
1) Loosen two self-locking nuts located at lower front portion of strut.
CAUTION:
^ When adjusting bolt needs to be loosened or tightened, hold its head with a wrench and turn self-locking nut.
^ Discard loosened self-locking nut and replace with a new one.
^ When performing toe-in adjustment, align as close to 0 mm (0 inch) as possible.
2) Turn camber adjusting bolt so that camber is set at the specification.
NOTE: Moving the adjusting bolt by one scale graduation changes camber by approximately 0° 10'.

3) Tighten the two self-locking nuts.
Tightening torque: 175 Nm (17.8 kgf-m, 129 ft.lb)
3. CASTER
Inspection
1) Place front wheel on turning radius gauge. Make sure ground contacting surfaces of front and rear wheels are set at the same height.
2) Set ST into the center of the wheel, and then install the wheel alignment gauge. ST 927380002 ADAPTER
3) Follow the operation manual for wheel alignment gauge to measure the caster angle.
NOTE: Refer to the "SPECIFICATIONS" for the caster values.
4. STEERING ANGLE
Inspection
1) Place vehicle on a turning radius gauge.
2) While depressing brake pedal, turn steering wheel fully to the left and right. With steering wheel held at each fully turned position, measure both the inner and outer wheel steering angle.
Steering angle:
Inner wheel 34.4° ±1.5°
Outer wheel 30.2° ±1.5°
Adjustment
Turn tie-rod to adjust steering angle of both inner and outer wheels.
CAUTION:
^ Because toe-in changes, adjustment values of right and left tie-rod should be the same.
^ Check toe-in.
^ Correct boot if it is twisted.
5. FRONT WHEEL TOE-IN
Inspection
1) Using a toe gauge, measure front wheel toe-in.
Toe-in: 0 ±3 mm (0 ±0.12 inch)
2) Mark rear sides of left and right tires at height corresponding to center of wheels and measure distance "A" between marks.
3) Move vehicle forward so that marks line up with front sides at height corresponding to center of wheels.
4) Measure distance "B" between left and right marks. Toe-in can then be obtained by the following equation:
A - B = Toe-in
Adjustment
1) Loosen the left and right side steering tie-rods lock nuts.
2) Turn the left and right tie rods 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 equal amounts (as viewed from the inside of the vehicle).
3) Tighten tie-rod lock nut.
Tightening torque: 83 Nm (8.5 kgf-m, 61.5 ft.lb)
CAUTION: Correct tie-rod boot, if it is twisted.
NOTE: Check the left and right wheel steering angle is within specifications.
6. REAR WHEEL TOE-IN
Inspection
1) Using a toe-in gauge, measure rear wheel toe-in.
Toe-in: 2 ±3 mm (0.08 ±0.12 inch)
2) Mark rear sides of left and right tires at height corresponding to center of wheels and measure distance "B" between marks.
3) Move vehicle forward so that marks line up with front sides at height corresponding to center of wheels.
4) Measure distance "A" between left and right marks. Toe-in can then be obtained by the following equation:
B - A = Toe-in
Adjustment
1) Loosen self-locking nut on inner side of rear lateral link.
CAUTION:
^ When loosening or tightening adjusting bolt, hold bolt head and turn self-locking nut.
^ Discard loosened self-locking nut and replace with a new one.
^ When performing toe-in adjustment, align as close to 0 mm (0 inch) as possible.
2) Turn adjusting bolt head until toe-in is at the specification.
NOTE: When left and right wheels are adjusted for toe-in at the same time, the movement of one scale graduation changes toe-in by approximately 3 mm (0.12 inch).
Table - Toe-in increased/decreased
3) Tighten self-locking nut.
Tightening torque: 100 Nm (10.2 kgf-m, 74 ft.lb)
7. THRUST ANGLE
Inspection
1) Position vehicle on a level surface.
2) Move vehicle 3 to 4 meters directly forward.
3) Determine locus of both front and rear axles.
4) Measure distance "L" between center line of loci of the axles.
Thrust angle: Less than 20' when "L" is equal to or less than 15 mm (0.59 inch).
Adjustment
1) Make thrust angle adjustments by turning toe-in adjusting bolts of rear suspension equally in the same direction.
2) When one rear wheel is adjusted in a toe-in direction, adjust the other rear wheel equally in toe-out direction, in order to make thrust angle adjustment.
3) When left and right adjusting bolts are turned incrementally by one graduation in the same direction, the thrust angle will change approximately 10' ["L" is almost equal to 7.5 mm (0.295 inch)].
Thrust angle: 0° ±20'
NOTE: Thrust angle refers to a mean value of left and right rear wheel toe angles in relation to vehicle body center line. Vehicle is driven straight in the thrust angle direction while swinging in the oblique direction depending on the degree of the mean thrust angle.
Thrust angle: r = (a - B)/2
a: Right rear wheel toe-in angle
B: Left rear wheel toe-in angle
NOTE: Here, use only positive toe-in values from each wheel to substitute for a and B in the equation.
