●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 preoiled, tighten as they are.

FRONT SUSPENSION ASSEMBLY
FRONT SUSPENSION ASSEMBLY
On-Vehicle Inspection and Service
PFP:54010
AES000WZ
Make sure that the mounting conditions (looseness, back lash) of each of the components and the component conditions (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.Place an iron bar or similar tool between transverse link and steering knuckle.
3.Measure axial end play by prying it up and down.
Axial end play : 0 mm (0 in)
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 Inspection |
AES000X0 |
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
Check the following:
1.Tires for improper air pressure and wear.
2.Road wheels for runout. Refer to WT-4, "ROAD WHEEL" .
3.Wheel bearing axial end play. Refer to FAX-7, "WHEEL BEARING INSPECTION" .
4.Transverse link ball joint axial end play. Refer to FSU-15, "INSPECTION AFTER REMOVAL" .
5.Strut operation.
6.Each mounting point of axle and suspension for looseness and deformation.
7.Each of suspension member, steering knuckle, strut and transverse link for cracks, deformation and other damage.
8.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 the 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 the hub bolt.
2.Screw the adapter into plate until it contacts the plate tightly.
3.Screw the center plate into the plate.
4.Insert the plate assembly on the guide bolt. Put the spring in, and then evenly screw the three guide nuts. When fastening the guide nuts, do not completely compress the spring.
