PRECAUTIONS
PRECAUTIONS
PFP:00001
PrecautionsEES002KG
lWhen installing the rubber bushings, the final tightening must be done under unladen condition and with
the tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immedi-
ately.
lUnladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The
spare tire, jack, hand tools, and mats are in their designated positions.
lAfter installing suspension components, check the wheel alignment.
lLock nuts are not reusable. Always use new lock nuts for installation. New lock nuts are pre-oiled, do not
apply any additional lubrication.

Front Suspension PartsEES002KM
Check front suspension parts for excessive play, cracks, wear and
other damage.
lShake each front wheel to check for excessive play.
If looseness is noted, inspect wheel bearing end play, then
check ball joint end play. Refer toFSU-15, "
Inspection".
lMake sure that the cotter pin is inserted in drive shaft end (4WD
models only).
lRetighten all nuts and bolts to the specified torque.
lCheck shock absorber for oil leakage and other damage.
lCheck suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.
Front Wheel AlignmentEES002KN
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer toWT-3, "
Inspection".
4. Check the wheel bearing axial end play. Refer toFA X - 5 , "
WHEEL BEARING INSPECTION".
5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer toFSU-21, "
Wheelarch Height (Unladen*1)". Suspension component torques : Refer toFSU-6,
"Components".SMA525A

CAMBER AND CASTER
1. Install CCK gauge attachment (SST: KV991040S0) as following procedure in wheel.
a. Remove wheel nuts (2), and install a guide bolt to hub bolt.
b. Screw center plate into plate.
c. Insert plate on guide bolt. Put spring in, and then evenly screw
both guide bolt nut. When fastening guide bolt nut, do not com-
pletely compress spring.
CAUTION:
Do not use any adapter for attaching the attachment.
d. Place the dent of alignment gauge onto the projection of center
plate and tightly contact them to measure.
2. Measure camber and caster of both the right and left wheels
with a suitable alignment gauge and adjust as necessary to
specifications.
3. If outside of the specified value, adjust camber and caster using
the adjusting bolts in the front lower link.
CAUTION:
After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 0°7' (0.12°), and caster changes about
0°12' (0.20°) with each graduation of one adjusting bolt. Refer to
table below for examples of lower link adjusting bolt effect on
camber and caster.
4. Tighten the adjusting bolt nuts to specification. Refer toFSU-6, "
Components".
TOE-IN
WARNING:
lAlways perform the following procedure on a flat surface.
lMake sure that no person is in front of the vehicle before pushing it.
1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2. Push the vehicle straight ahead about 5 m (16 ft).

3. Put a mark on base line of the tread (rear side) of both front tires
at the same height as hub center as shown. These marks are
measuring points.
4. Measure the distance “A” on the rear side of the front tires as
shown.
5. Push the vehicle slowly ahead to rotate the wheels 180°
degrees (1/2 a turn).
CAUTION:
If the wheels have rotated more than 180°degrees (1/2
turn), start this procedure again from the beginning. Never
push the vehicle backward.
6. Measure the distance “B” on the front side of the front tires at the
same marks as shown. Total toe-in is calculated as “A” – “B”.
7. Adjust the toe-in by varying the length of the steering outer tie-
rods.
a. Loosen the outer tie-rod lock nuts.
b. Adjust the toe-in by screwing the outer tie-rods in or out.
c. Tighten the outer tie-rod lock nuts to specification.
FRONT WHEEL TURNING ANGLE
NOTE:
Check front wheel turning angle after the toe-in inspection.
1. Place front wheels on turning radius gauges in straight ahead
position and rear wheels on stands so that vehicle can be level.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
2. Start engine and run at idle, turn steering wheel all the way right
and left, measure the turning angle.
lAny turning angles are not adjustable. If any of steering
angles are out of the specification, check if the following parts
are worn or damaged.
–Steering gear
–Steering column
–Front suspension components
If found that they are worn or damaged, replace them with new ones.

Removal and InstallationEES002KO
REMOVAL
1. Remove the wheel.
2. Support the lower link using a suitable jack.
3. Remove connecting rod upper joints from stabilizer bar. Refer toFSU-6, "
Components".
lSwing stabilizer bar down, repositioning it out of the way to access shock absorber lower mount.
4. Remove the shock absorber lower bolt and nut.
5. Remove the three shock absorber upper mounting nuts.
6. Remove the coil spring and shock absorber assembly.
lTurn steering knuckle out to gain enough clearance for
removal.
INSTALLATION
Installation is in the reverse order of removal.
lThe step in the strut assembly lower seat faces outside of vehicle.
lTighten all nuts and bolts to specification. Refer toFSU-6, "Components".
lWhen installing wheel and tire, refer toWT-5, "Rotation".
Disassembly and AssemblyEES002KP
DISASSEMBLY
1. Install strut attachment to strut and fix it in a vise.
CAUTION:
When installing strut attachment, wrap a shop cloth around
strut to protect it from damage.
2. Slightly loosen piston rod lock nut.
WARNING:
Do not remove piston rod lock nut completely. If it is
removed completely, coil spring jumps out and may cause
serious damage or injury.
3. Compress the spring using commercial service tool until the
shock absorber mounting insulator can be turned by hand.
WARNING:
Make sure that the pawls of the two spring compressors are firmly hooked on the spring. The
spring compressors must be tightened alternately and evenly so as not to tilt the spring.
4. Remove the piston rod lock nut.
lDiscard the piston rod lock nut, use a new nut for assembly.
5. Remove the components from the shock absorber.
lKeep the spring compressed in the commercial service tool if
reusing it for assembly.
