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.
