STABILIZER BAR AND BUSHING CHECK
BAR
Inspect for damage or deformation. If defective, replace.
BUSHING
Inspect for damage, wear or deterioration. If defective, replace.
STRUT DAMPER AND / OR COIL SPRING
CHECK
1) Inspect strut for oil leakage. If strut is found faulty, replace it as
an assembly unit, because it can not be disassembled.
2) Strut function check
Check and adjust tire pressures as specified.
Bounce body three or four times continuously by pushing front
end on the side with strut to be checked. Apply the same amount
of force at each push and note strut resistance both when
pushed and rebounding.
Also, note how many times vehicle body rebounds before com-
ing to stop after hands are off. Do the same for strut on the other
side.
Compare strut resistance and number of rebound on the right
with those on the left.
And they must be equal in both. With proper strut, body should
come to stop the moment hands are off or after only one or two
small rebounds. If struts are suspected, compare them with
known good vehicle or strut.
3) Inspect for damage or deformation.
4) Inspect strut boot for damage or crack.
5) Inspect for cracks or deformation in spring seat.
6) Inspect for deterioration of bump stopper.
7) Inspect strut mount for wear, cracks or deformation.
Replace any parts found defective in steps 2) ± 7).
SUSPENSION ARM / KNUCKLE CHECK
Inspect for cracks, deformation or damage.

GENERAL DESCRIPTION
The drive shaft joint is a constant velocity joint (C.V. joint) which slides in the axial direction. The joint is composed
of an outer race, cage, inner race and balls. In the turning direction, the joint rotates in the same way as a ball bear-
ing. The balls lock rotation completely and transmit drive. In addition this vehicle is also characterized by a function
that the shaft can slide through the balls in the grooves of the outer race in the extension / contraction direction of
the drive shaft.

any malcondition is found in joint, replace it as assem-
bly.

Do not disassemble ball joint of differential side joint.
If any malcondition is found in ball joint, replace differ-
ential side joint assembly.
INSPECTION

Check boots for breakage or deterioration. Replace them as nec-
essary.

Check circlip, snap ring and boot bands for breakage or deforma-
tion. Replace as necessary.
CLEANING

Wash disassembled parts (except boots) in degreaser. After
washing, dry parts completely by blowing air.

Clean boots with cloth. DO NOT wash boots in degreaser, such
as gasoline or kerosene, etc.
Washing in degreaser causes deterioration of boot.

CAUTION:

To prevent any problem caused by washing solution, do
not wash joint boots. Degreasing of those parts with cloth
is allowed.

For M / T vehicle with H25 engine
To ensure full performance of joint as designed, be sure
to distinguish between two types of grease in repair set
and apply specified volume to respective joint. i.e. yellow
grease to wheel side joint and black one to differential
side.

Bend each boot band against forward rotation.

Do not squeeze or distort boot when fastening it with
bands.
Distorted boot caused by squeezing air may reduce its du-
rability.
1) Fully apply joint grease to wheel side joint.
Use joint grease in the tube included in spare part.
2) Fit wheel side boot on shaft.
Fill up inside of boot with joint grease of about 90 gram.
Before fixing boot band, insert screwdriver into boot on joint side
and allow air to enter boot so that air pressure in boot becomes
the same as atmospheric pressure.
3) Fixing boot band.
4) Install boot onto drive shaft till its small diameter side fits to shaft
groove and fix there with boot band.
5) Install cage to shaft.
CAUTION:
Install cage directing smaller outside diameter side to
shaft end.
6) Install circlip by using snap ring plier.

5B-2 FRONT BRAKE
GENERAL DESCRIPTION
DISC BRAKE CALIPER ASSEMBLY
This caliper is mounted to the brake caliper carrier with two caliper pin bolts. Hydraulic force, created by applying
force to the brake pedal, is converted by the caliper to friction. The hydraulic force acts equally against the piston
and the bottom of the caliper bore to move the piston outward and to move (slide) the caliper inward, resulting in
a clamping action on the disc. This clamping action forces the pads (linings against the disc, creating friction to
stop the vehicle.
NOTE:

Lubricate parts as specified. Do not use lubricated shop air on brake parts as damage to rubber compo-
nents may result. If any component is removed or line disconnected, bleed the brake system.
Replace pads in axle sets only. The torque values specified are for dry, unlubricated fasteners.

For identification of the brake caliper type, see maker name or mark on brake caliper as shown.
