Front and Rear Suspension
WheelAlignment
The suspension can be adjusted for front camber, front
toe, and rear toe. However, each of these adjustments
are interrelated to each other. For example, when you
adjust the toe, the camber changes. Therefore, you
must adjust the front wheel alignment whenever you
adjust the camber or toe.
Pre-Alignment Checks
For proper inspection and adjustment of the wheel
alignment, do these checks:
1. Release the parking brake to avoid an incorrect
measurement.
Make sure the suspension is not modified.
Check the tire size and tire pressure
Tire size:
Front/rear: 195/60R15
Tire pressure:
Front: 230 kPa {2.3 kgf/cm',33 psil
Rear: 210 kPa |'2.1 kgf/cm', 30 psi)
Check the runout of the wheels and tires.
Check the suspension ball joints. (Hold a wheel
with your hands, and move it up and down and
right and left to check for wobbling),
2.
3.
Bounce the vehicle up and down several times to
stabilize the suspension.

Front Caster lnspection
Use commerciallv available comDuterized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
eouioment manufacturer's instructions.
Check the caster angle. lf the caster angle is not within
the specification, check for bent or damaged
susoensron comoonents.
Front caster angle: 1'40't 1"
\

Front Toe Inspection/Adjustment
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. Center the steering wheel spokes.
2. Checkthetoe. lf it is not with in the specif ication, go
to step 3.
Front toe-in: 0 t 3 mm {0 t 0.12 in.)
3. Loosen the locknut (A) while holding the tie-rod end(B ).

5.
Turn the tie-rod (C) untilthe toe is correct.
After adjusting, tighten the locknut while holding
the tie-rod end. Make sure the toe setting does not
change.
1,;
Rear Toe Inspection/Adiustment
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, Release the parking brake.
2. Checkthe toe. lf it is not within the specification. go
to step 3.
Rear toe-in {inspection):
1 1 3 mm (0.04 a 0.12 in.)
3. Loosen the self-locking nut (A)while holding the
adjusting bolt (B).
Do not loosen lhe special bolts (C) on the
lower arm to adjust the alignment.
4. Replace the self-locking nut with a new one, and
lightly tighten.
NOTE: Always use a new self-locking nut whenever
it has been loosened.
Turn the adjusting bolt until the toe is correct.
Rear toe.in (adiustment):
2 ' , mm {0.08 "' ,. in.}
Tighten the self-locking nut to the specified torque
while holding the adjusting bolt.

Turning Angle Inspection
Use commercially-available computerized four wheel
alignment equipment to measure wheel alignment(caster. camber, toe, and turning angle). Followthe
equiDment manufacturer's instructions.
1. Turn the steering wheel fullytotherightandleft
while applying the brake, and check the turning
angles of both front wheels, lf the turning angle is
not within the specification or the inward turning
angles differ between the right and left side, go to
steD 2.
Turning angle:
lnward: 34'00'+ 2'
Outward: 28'00' {reference)
Check the toe. lf it is correct, but the turning angle
is not within the specification, check ior bent or
damaged suspension components,

Wheel Bearing End Play Inspec'tion
1. Raise lhe vehicle, and support it with safety stands
in the proper location (see page 1-8). Remove the
wheels.
2. Install suita ble f lat washe rs (A) and wheel nuts, and
tighten the nuts to the specified torque to hold the
brake disc securely against the hub.
Front:
108 N.m(11.0 kgf.m,80 rbf.ft)
Rear:
108 N.m
3. Set up the dial gauge against the hub flange as
shown, and measure the bearing end play moving
the brake disc inward and outward.
Bearing end play:
Standard:
Front/rear: 0 0.05 mm {0 0.002 in.}
4. lf the bearing end play is more than the standard,
replace the wheel bearing.
