• After removing/installing or replacing suspension components and steering components, check wheel align-
ment. Refer to
FSU-5, "Wheel Alignment Inspection"
• After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to
ment of Steering Angle Sensor Neutral Position"
• Check the following item after service.
- Installation condition of wheel sensor harness.

Disassembly and Assembly
INFOID:0000000001327541
DISASSEMBLY
NOTE:
Make sure piston rod on strut is not damaged when removing components from strut assembly.
1.
Install strut attachment (SST) to strut and fix it in a vise.
CAUTION:
When installing strut attachment (SST) to strut, wrap a shop
cloth around strut to protect it from damage.
2.
Using a spring compressor (commercial service tool), compress
coil spring between spring upper seat and spring lower seat (on
strut) until coil spring is free.
CAUTION:
Be sure spring compressor (commercial service tool) is
securely attached to coil spring. Compress coil spring.
3.
After making sure coil spring is free between spring upper seat
and spring lower seat of strut, then remove piston rod lock nut.
4.
Remove mounting insulator, mounting insulator bracket, mount-
ing bearing, spring upper seat, spring upper rubber seat, bound
bumper. Then remove coil spring and spring lower rubber seat
from strut.
5.
Gradually release spring compressor (commercial service tool), and remove coil spring.
CAUTION:
Loosen spring compressor while making sure coil spring attachment position does not move.
6.
Remove strut attachment (SST) from strut.
INSPECTION AFTER DISASSEMBLY
Strut Inspection
• Check strut for deformation, cracks, damage, and replace if necessary.
• Check piston rod for damage, uneven wear or distortion, and replace if necessary.
• Check welded and sealed areas for oil leakage, and replace if necessary.
Mounting Insulator and Rubber Parts Inspection
Check mounting insulator for cracks and rubber parts for wear. Replace them if necessary.
Coil Spring Inspection
Check coil spring for cracks, wear or damage, and replace if necessary.

COIL SPRING AND STRUT
Make sure piston rod on strut is not damaged when attaching components to strut.
1.
Install strut attachment (SST) to strut and fix it in a vise.
CAUTION:
When installing strut attachment (SST) to strut, wrap a shop
cloth around strut to protect it from damage.
2.
Compress coil spring using a spring compressor (commercial service tool), and install it onto strut.
CAUTION:
• Face tube side of coil spring downward. Align lower end
to spring rubber seat as shown in the figure.
• Be sure spring compressor (commercial service tool) is
securely attached to coil spring. Compress coil spring.
3.
Apply soapy water to bound bumper and insert into mounting
insulator.
CAUTION:
Do not use machine oil.
4.
Install mounting insulator bracket, mounting bearing, bound
bumper, spring upper seat, spring upper rubber seat and spring
lower rubber seat.
• Installation position of spring upper seat is as shown in the fig-
ure.
5.
Fix mounting insulator, then tighten piston rod lock nut with
specified torque.
CAUTION:
Be careful not to deform mounting insulator bracket.
6.
Gradually release spring compressor (commercial service tool),
and remove coil spring.
CAUTION:
Loosen spring compressor while making sure coil spring
attachment position does not move.
7.
Remove strut attachment (SST) from strut.
