FRONT SUSPENSION ASSEMBLY

FRONT SUSPENSION ASSEMBLY

PFP:54010

On-Vehicle Inspection and Service

AES0008H

Check that the mounting conditions (looseness, back lash) of each component and component statues (wear,
damage) are normal.

INSPECTION OF SUSPENSION ARM BALL JOINT END PLAY

1.

Set front wheels in a straight-ahead position. Do not depress brake pedal.

2.

Measure axial end play by installing and moving up/down with an iron pry bar or something similar
between suspension arm and steering knuckle.

CAUTION:

Be careful not to damage ball joint boot.

STRUT INSPECTION

Check strut for oil leakage, damage and replace if necessary.

Wheel Alignment Inspection

AES0008I

DESCRIPTION

Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. Spare tire, jack, hand tools and mats in designated positions.

PRELIMINARY INSPECTION

1.

Check tires for improper air pressure and wear.

2.

Check road wheels for runout.

3.

Check wheel bearing axial end play. 

4.

Check suspension arm ball joint axial end play.

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 posture.

INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES.

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.

Using a CCK Gauge

1.

Remove wheel nuts (3), and install a guide bolt (special service
tool) to hub bolt.

2.

Screw adapter (special service tool) into plate body (special ser-
vice tool) until it contacts body tightly.

3.

Screw center plate (special service tool) into plate body (special
service tool).

4.

Insert plate (special service tool) on guide bolt (special service
tool). Put spring in, and then evenly screw in guide bolt nut (spe-
cial service tool). When fastening guide bolt nut, do not com-
pletely compress spring.

Standard value

Axial end play

: 0 mm (0 in)
