1. WHEEL ARCH HEIGHT (FRONT AND
REAR)
1) Adjust tire pressure to specifications.
2) Set vehicle under ªcurb weightº conditions.
(Empty luggage compartment, install spare tire,jack, service tools, and top up fuel tank.)
3) Set steering wheel in a wheel-forward position.
4) Suspend thread from wheel arch (point ªAº in
figure below) to determine a point directly above
center of spindle.
5) Measure distance between measuring point
and center of spindle.

2. CAMBER (FRONT AND REAR)
IInspection
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.

NOTE:
Refer to the ªSPECIFICATIONS AND SERVICE
DATAº for the camber values.
IFront Camber Adjustment
1) Loosen two self-locking nuts located at lower
front portion of strut.
CAUTION:
IWhen adjusting bolt needs to be loosened or
tightened, hold its head with a wrench and turn
self-locking nut.
IDiscard loosened self-locking nut and
replace with a new one.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 0É10¢.

IInspection
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

4. FRONT WHEEL TOE-IN
IInspection
1) Using a toe gauge, measure front wheel toe-in.
Toe-in:
0
±3mm(±0.12 in)
2) Mark rear sides of left and right tires at height
corresponding to center of spindles and measure
distance ªBº between marks.
3) Move vehicle forward so that marks line up with
front sides at height corresponding to center of
spindles.
4) Measure distance ªAº between left and right
marks. Toe-in can then be obtained by the follow-
ing equation:
B þ A = Toe-in
H4M1279
IAdjustment
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:

±5 N´m (8.5±0.5 kg-m, 61.5±3.6 ft-lb)
CAUTION:
Correct tie-rod boot, if it is twisted.
NOTE:
Check the left and right wheel steering angle is
within specifications.
