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 Camber Inspection
Use commercially available computerized four wheel
alignment equipment to measure wheel alignment(caster, camber, toe, and turning angle). Follow the
equipment manufacturer's instructions.
Check the camber angle. lf the camber angle is not
within the specification, adjust the camber.
Front camber angle: 0"30' t 45'
Front Camber Adjustment
The front camber can be adjusted by exchanging one or
both of the damDer Dinch bolts with the smaller
diameter adjusting bolt(s). The difference between the
adjusting bolt diameter and the pinch bolt hole
diameter allows a small range of adjustment.

Raise the front of the vehicle, and support it with
safety stands in the proper location (see page 1-8).
Remove the front wheels.
Loosen the damper pinch nuts and bolts (A), and
adjust the camber by moving the bottom of the
damper within the range of the damper pinch bolt

Reinstall the front wheels. Lower the front of the
veh icle to the ground, and bounce the vehicle
several times to stabilize the suspension.
Check the camber angle. lf it is within the
specification, check the front toe. lf it is not within
the specification, go to step 6.

Remove the front wheels.
Replace the damper pinch bolts with the adjusting
bolts (A), and adjust the camber angle.
NOTE: The camber angle can be adjusted up to t
15' (center of tolerance) by replacing one damper
pinch bolt with the adjusting bolt. The camber
angle can be adjusted up to a 30' by replacing both
upper and lower damper pinch bolts with the
adjusting bolts.

Reinstall the front wheels. Lower the front of the
vehicle to the ground, and bounce the vehicle
several times to stabilize the suspension.
Check the camber angle. lf it is within the
specification, check the front toe. and adjust it if
necessary. lf it is not within the specification,
readjust, and recheck. lJ the camber angle cannot
be adjusted to the specification, check for bent or
damaged suspension components.

BallJoint Removal
Special Tools Required
Ball ioint remover.2S mm 07MAC-SL00200
Always use a ball joint remover to disconnect a ball
joint. Do not strike the housing or any other part of
the ball joint connection to disconnect it.
'1, Install a hex nut (A) ontothethreadsoftheballjoint
{B). Make sure the nut is flush with the balljoint pin
end to prevent damage to the threaded end of the
ball ioint oin.
Apply grease to the special tool on the areas shown(A). This will ease installation of the tool and
prevent damage to the pressure bolt {B) threads.

After adjusting the adjusting bolt, make sure the
head (C) of the adjusting bolt is in the position
shown to allow the jaw to pivot.
With a wrench, tighten the pressure bolt until the
ball ioint pin pops loose from the steering arm or
knuckle. lf necessary. apply penetrating type
lubricant to loosen the ball joint pin
NOTE: Do not use pneumatic or electric tools on
the pressure bolt.
Remove the tool, then remove the nut from the end
ofthe balljoint pin, and pullthe balljoint out ofthe
steering arm or knuckle. Inspectthe balljoint boot,
and replace it if damaged.
