Disassembly and Assembly
INFOID:0000000006161680
DISASSEMBLY
1. Set the shock absorber in a vise, then loosen (without removing)
the piston rod lock nut as shown.
CAUTION:
Do not remove piston rod lock nut at this time.
2. Compress the spring using tool until the shock absorber mount-
ing insulator can be turned by hand.
WARNING:
Make sure that the pawls of the two tools are firmly hooked
on the spring. The spring compressors must be tightened
alternately and evenly so as not to tilt the spring.
3. Remove the piston rod lock nut.
• Discard the piston rod lock nut, use a new nut for assembly.
INSPECTION AFTER DISASSEMBLY
Shock Absorber Assembly
• Check for smooth operation through a full stroke, both compression and extension.
• Check for oil leakage on welded or gland packing portions.
• Check piston rod for cracks, deformation or other damage and replace if necessary.
Mounting Insulator and Rubber Parts
Check cemented rubber-to-metal portion for separation or cracks. Check rubber parts for deterioration and
replace if necessary.
Coil Spring
• Check for cracks, deformation or other damage and replace if necessary.
• Check the free spring height.

COIL SPRING AND SHOCK ABSORBER
1. When installing coil spring on shock absorber, the lower end (2)
and upper end (3) must be positioned as shown.
• Shock absorber mounting insulator (1)
•
: Flat tail
2. Install upper spring insulator (3) with studs located in line with
lower shock mount and in lower seat step (2). The lower seat
step (2) in the shock absorber assembly (1) faces outside of
vehicle.
