PFP:00001
CautionEES0007C
● Final 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.
●“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare tire,
jack, and hand tools should be unloaded.
●After installing the removed suspension parts, always check wheel alignment and adjust if necessary.
●Replace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.

REAR SUSPENSION ASSEMBLY
On-Vehicle Inspection and Service
EES0007F
Check axle and suspension parts for excessive play, wear, and damage.
●Move rear wheels (RH/LH) to check abnormal free play.
●Retighten all nuts and bolts to the specified torque.
●Check strut for oil leakage and damage.
Wheel AlignmentEES0007G
DESCRIPTION
●Measure 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.
●If 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.
●Always perform following procedure on a flat surface.
●Make 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:

Removal and InstallationEES0007H
REMOVAL
1. Remove tires.
2. Remove brake hose lock plate and remove brake hose from strut.
3. Remove mounting nuts and washers on upper portion of stabilizer connecting rod.
4. Remove strut-to-axle housing mounting bolts and nuts.
5. Remove luggage side lower finisher in luggage compartment. Remove mounting nuts on strut spacer.
Then remove strut from vehicle.
INSTALLATION
●Refer to RSU-5, "Components" for tightening torque. Install in the reverse order of removal.
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.
●Remove strut spacer, 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
●Check strut for deformation, cracks, and damage, and replace if necessary.
●Check piston rod for damage, uneven wear, and distortion, and replace if necessary.
●Check welded and sealed areas for oil leakage, and replace if necessary.
Insulator and Rubber parts.
●Check strut mount insulator for cracks and rubber parts for wear. Replace them if necessary.
Coil Spring
●Check coil spring for cracks, deformation, and damage, and replace if necessary.

strut mount insulator and strut spacer. Position piston rod lock
nut.
CAUTION:
Do not reuse piston rod lock nut.
3. As shown in the figure, set spring upper seat. “ ” Mark on it
should face outside of vehicle.
4. Be sure coil spring is properly set in upper and lower rubber
seats. Gradually release a spring compressor.
