PRECAUTION A
PRECAUTIONS
Precautions for Suspension INFOID:0000000003811137
B
CAUTION:
• When installing rubber bushings, the final tightening must be carried out under unladen conditions
with tires on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil. C
- Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools
and mats are in designated positions.
• After servicing suspension parts, be sure to check wheel alignment. D
• Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are
pre-oiled, tighten as they are.

WHEEL ALIGNMENT
WHEEL ALIGNMENT
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
Check the following:
• Tires for improper air pressure and wear
• Road wheels for runout: refer to WT-2, "Inspection".
• Wheel bearing axial end play: refer to RAX-3, "Inspection".
• Shock absorber operation
• Each mounting point of axle and suspension for looseness and deformation
• Each of lower link, upper link, rear suspension member, suspension arm and shock absorber for cracks,
deformation, and other damage
• Vehicle height (posture)
CAMBER
• Measure camber of both right and left wheels with a suitable alignment gauge.
• If camber is outside specified range, adjust with adjusting bolt in
lower. Refer to RSU-7, "Adjustment".
Standard
Camber: Refer to RSU-20, "Wheel Alignment".
SRA096A
TOE-IN
Measure toe-in by the following procedure.
WARNING:
• Always perform the following procedure on a flat surface.
• Make sure that no person is in front of vehicle before pushing it.
1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2. Push vehicle straight ahead about 5 m (16 ft).
3. Put matching mark (A) on base line of the tread (rear side) of
both tires at the same height of hub center. These are measur-
ing points.

If the wheels rotates more than 180 degrees (1/2 turn), start this B
procedure again from the beginning. Do not push the vehicle
backward.
6. Measure distance (B) (front side).
