Disassembly and Assembly

NES00028

DISASSEMBLY

NOTE:
Make sure piston rod on shock absorber is not damaged when removing components from shock absorber.

1.

Install strut attachment (SST) to shock absorber and fix it in a
vise.

CAUTION:

When installing strut attachment (SST) to shock absorber,
wrap a shop cloth around shock absorber 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
shock absorber) until coil spring is free.

CAUTION:

Be sure spring compressor (commercial service tool) is
securely attached to coil spring. Compress coil spring.

3.

Check that coil spring between spring upper seat and spring lower seat is free and then secure piston rod
tip so that piston rod does not turn, and remove piston rod lock nut.

4.

Remove mounting insulator, bound bumper, spring upper seat. Then remove coil spring from shock
absorber.

5.

Gradually release spring compressor (commercial service tool), and remove coil spring.

CAUTION:

Loosen while marking sure coil spring attachment position does not move.

6.

Remove strut attachment (SST) from shock absorber.

INSPECTION AFTER DISASSEMBLY
Shock Absorber Inspection

●

Check shock absorber 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, damage, and replace if necessary.

ASSEMBLY

NOTE:
Make sure piston rod on shock absorber is not damaged when attaching components to shock absorber.

service tool), and install it onto shock absorber.

CAUTION:

●

Install coil spring as shown in the figure with large diame-
ter side (A) up and small diameter side (B) down.

●

Be sure spring compressor (commercial service tool) is
securely attached to coil spring. Compress coil spring.

3.
