FRONT SUSPENSION ASSEMBLY
On-Vehicle Inspection and Service
EES000TW
Check that the mounting conditions (looseness, back lash) of each component and component statues (wear,
damage) are normal.
INSPECTION LOWER 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 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
EES000TX
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 lower 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 (2), 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.
