PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEES0007C
lFinal tightening of bushings must be carried out under unladen condition with tires on the ground. Oil will
shorten life of bushings. Be sure to wipe off any spilled oil.
l“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare tire,
jack, and hand tools should be unloaded.
lAfter installing the removed suspension parts, always check wheel alignment and adjust if necessary.
lReplace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.
Precautions for Brake SystemEES000JB
lWhen installing rubber parts, final tightening must be carried out
under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake tubes.
lAfter installing removed suspension parts, check wheel align-
ment and adjust if necessary.
lAlways torque brake lines when installing.

On-Vehicle Inspection and Service
EES0007F
Check axle and suspension parts for excessive play, wear, and damage.
lMove rear wheels (RH/LH) to check abnormal free play.
lRetighten all nuts and bolts to the specified torque.
lCheck strut for oil leakage and damage.
Wheel AlignmentEES0007G
DESCRIPTION
lMeasure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tire, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check strut operation.
5. Check each mounting point of axle and suspension for looseness and deformation.
6. Check each link and arm for cracks, deformation, and other damage.
7. Check the vehicle posture.
CAMBER
Camber is preset at factory and cannot be adjusted.
lIf the camber is not within specification, inspect and replace any damaged or worn rear suspension parts.
TOE-IN
Measure toe-in using the following procedure.
lAlways perform following procedure on a flat surface.
lMake sure that no person is in front of the vehicle before push-
ing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of tread (rear side) of both tires at the
same height as hub center.this mark is a measuring points.

4. Measure distance “A” (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180 degrees
(1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn), try the
above procedure again from the beginning. Never push vehicle
backward.
6. Measure distance “B” (front tires).
7. If measured value is outside standard, adjust it with adjusting
bolt on rear parallel link.
CAUTION:
Be sure to adjust equally on RH and LH side with adjusting
bolt.Total toe-in:

Disassembly and AssemblyEES0007I
DISASSEMBLY
1. Install strut attachment to strut and fix it in a vise.
CAUTION:
When installing a strut attachment, cover strut with shop
cloth to avoid damage.
2. Remove cap and slightly loosen piston rod lock nut.
CAUTION:
Do not remove piston rod lock nut completely. If it is
removed completely, coil spring jumps out and may cause
serious damage or injury.
3. Compress coil spring using a spring compressor.
CAUTION:
Be sure spring compressor is securely attached to coil spring. Compress coil spring.
4. After making sure coil spring is free between upper and lower seats after Step 3. Remove piston rod lock
nut.
5. Remove small parts on strut.
lRemove strut spacer, strut mounting seal, strut mount insulator, spring upper seat, upper rubber seat,
and bound bumper. Then remove coil spring from strut.
6. Gradually release spring compressor, and remove coil spring.
INSPECTION AFTER DISASSEMBLY
Strut
lCheck strut for deformation, cracks, and damage, and replace if necessary.
lCheck piston rod for damage, uneven wear, and distortion, and replace if necessary.
lCheck welded and sealed areas for oil leakage, and replace if necessary.
Bushing
lCheck bushing for cracks and damage, and replace if necessary.
