On-Vehicle Inspection and ServiceAES000MJ
Make sure the mounting conditions (looseness, back lash) of each component and component status (wear,
damage) are normal.
INSPECTION OF SUSPENSION ARM BALL JOINT END PLAY
Measure axial end play by installing and moving up/down between suspension arm and axle with an iron pry
bar or something similar.
CAUTION:
Be careful not to damage ball joint boot.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace if necessary.
Wheel Alignment InspectionAES000MK
DESCRIPTION
Measure wheel alignment under unladen conditions. “Unladen conditions” mean that fuel, engine coolant, and
lubricant are full. Spare tire, 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.
3. Check wheel bearing axial end play.
4. Check suspension arm ball joint axial end play.
5. Check shock absorber operation.
6. Check each mounting part of axle and suspension for looseness and deformation.
7. Check each link, arm and member for cracks, deformation, and other damage.
8. Check vehicle posture.
CAMBER INSPECTION
Measure camber of both right and left wheels with a suitable align-
ment gauge and adjust in accordance with the following procedures.
If outside the standard value, adjust with adjusting bolt in front lower
link.
NOTE:
After adjusting camber, be sure to check toe-in.Axial end play : 0 mm (0 in)
Camber : Refer to RSU-18, "
Wheel Alignment" .
