1) Adjust tire pressure to specifications.

2) Set vehicle under “curb weight”conditions. (Empty luggage compartment, install spare tire, jack, ser-

vice tools, and top up fuel tank.)

3) Set steering wheel in a wheel-forward position.

4) Suspend thread from wheel arch (point “A”in figure below) to determine a point directly above center

of spindle.

5) Measure distance between measuring point “A”and center of spindle.

쐌Inspection

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.

쐌Front Camber Adjustment

1) Loosen two self-locking nuts located at lower

front portion of strut.

CAUTION:

쐌When adjusting bolt needs to be loosened or

tightened, hold its head with a wrench and turn

self-locking nut.

쐌Discard loosened self-locking nut and

replace with a new one.

쐌When performing toe-in adjustment, align as

close to 0 mm (0 in) 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′.

4. FRONT WHEEL TOE-IN S202116A1004

쐌Inspection

1) Using a toe gauge, measure front wheel toe-in.

Toe-in:

0±3mm(0±0.12 in)

2) Mark rear sides of left and right tires at height

corresponding to center of spindles and measure

distance “A”between marks.

3) Move vehicle forward so that marks line up with

front sides at height corresponding to center of

spindles.

4) Measure distance “B”between left and right

marks. Toe-in can then be obtained by the follow-

ing equation:

A−B = Toe-in
