PRECAUTIONS

PRECAUTIONSPFP:00001
CautionBES0003G

When installing rubber bushings, final tightening must be performed under unladen conditions with tires
on ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
–Unladen conditions mean that fuel, engine coolant and lubricant are full. A spare tire, a jack, hand tools
and mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Self-lock nut are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

On-Vehicle Inspection BES0003K
Make sure that the mounting conditions (looseness, back lash) of each component and component status
(wear, damage) are normal.
INSPECTION OF TRANSVERSE LINK BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Measure axial end play by placing an iron pry bar or a similar item between suspension arm and strut
assembly and prying up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
STRUT INSPECTION
Check for oil leakage, damage, and breakage of installation positions.
Wheel Alignment InspectionBES0003L
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen” conditions mean that fuel, engine coolant, and lubricant are full. A spare tire, a jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
1. Check Tires for improper air pressure and wear.
2. Check Road wheels for runout. Refer to WT-3, "
ROAD WHEEL" .
3. Check Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Check Transverse link ball joint axial end play. Refer to FSU-14, "
INSPECTION AFTER REMOVAL" .
5. Check Strut operation.
6. Check Each mounting point of axle and suspension for looseness and deformation.
7. Check Each link, rod, and member for cracks, deformation and other damage.
8. Check Vehicle height (posture).
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES.

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install CCK gauge attachment [SST:KV991040S0] with the following procedure on wheel, then measure wheel
alignment.
1. Remove three wheel nuts, and install the guide bolts to hub
bolts.
2. Screw adapter into the plate until it contacts the plate tightly.
3. Screw center plate into the plate.
4. Insert plate on guide bolt. Put spring in, and then evenly screw
both guide bolt nuts. When fastening guide bolt nuts, do not
completely compress the spring.Axial end play : 0 mm (0 in)

5. Place the dent of alignment gauge onto the projection of center
plate and tightly contact them to measure.
CAUTION:
If camber, caster, or kingpin inclination angle is outside the
standard, check front suspension parts for wear and dam-
age. and Replace suspect parts if necessary.
Toe-In Inspection
Measure toe-in using the following procedure.
WARNING:

Always perform the following procedure on a flat surface.

Make sure that no person is in front of vehicle before push-
ing it.
1. Bounce front of vehicle up and down to stabilize the vehicle
height (posture).
2. Push vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. These are measuring points.
4. Measure distance “A” (rear side).
5. Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
NOTE:
If the wheels have rotated more than 180° degrees (1/2 turn),
start this procedure again from the beginning. Do not push the
vehicle backward.
6. Measure distance “B” (front side).Camber, caster, kingpin inclination angles:

CATIONS (SDS)" .

Removal and Installation BES0003N
REMOVAL
1. Remove cowl top panel and hood. Install engine slinger, and then hoist engine. (VQ35DE models) Refer
to EI-21, "
COWL TOP" , BL-13, "HOOD" .
2. Remove tires from vehicle.
3. Remove wheel sensor from steering knuckle. Refer to BRC-33, "
WHEEL SENSORS" .
CAUTION:
Do not pull on wheel sensor harness.
4. Remove torque member fixing bolts. Hang torque member in a place where it will not interfere with work.
Refer to BR-26, "
FRONT DISC BRAKE" .
NOTE:
Do not depress brake pedal while brake caliper is removed.
5. Remove undercover and splash guard.
