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:

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).

1) Loosen self-locking nut on inner side of rear
lateral link.
CAUTION:
IWhen loosening or tightening adjusting bolt,
hold bolt head and turn self-locking nut.
IDiscard loosened self-locking nut and
replace with a new one.
G4M0486
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 in).

6. THRUST ANGLE
IInspection
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 ªLº between center line of
loci of the axles.
Thrust angle:
Less than 20
¢when ªLº is equal to or
less than 15 mm (0.59 in).
G4M0488
IAdjustment
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 approxi-
mately 10' [ªLº is almost equal to 7.5 mm (0.295
in)].
Thrust angle:

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 direc-
tion depending on the degree of the mean thrust
angle.

NOTE:
Here, use only positive toe-in values from each
wheel to substitute foraandbin the equation.
7. STEERING ANGLE
IInspection
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.
