INSPECTION AFTER DISASSEMBLY
Shock Absorber Inspection
Check shock absorber for deformation, cracks, damage, and replace if necessary.
Check piston rod for damage, uneven wear, 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.
ASSEMBLY
NOTE:
Make sure piston rod on shock absorber is not damaged when attaching components to 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. Compress coil spring using a spring compressor (commercial
service tool), and install it onto shock absorber.
CAUTION:
Install coil spring 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.

Revision: 2006 November2007 350Z
4. Attach spring upper seat and mounting insulator as shown in the
figure.
CAUTION:
Make sure coil spring is securely seated in spring mount-
ing groove of spring upper seat.
The bottom part of spring should be at the position of A
point of spring seat.
5. Secure piston rod tip so that piston rod does not turn, and
tighten the specified torque on piston rod lock nut.
6. Gradually release spring compressor (commercial service tool),
and remove coil spring.
CAUTION:
Loosen spring compressor (commercial service tool) while
making sure coil spring attachment position does not
move.
7. Remove strut attachment (SST) from shock absorber.
