Disassembly and AssemblyEES0007I
DISASSEMBLY
1. Install strut attachment (SST) to strut and fix it in a vise.
CAUTION:
When installing a strut attachment (SST), cover strut with
shop cloth to avoid damage.
2. Remove cap and slightly loosen piston rod lock nut.
CAUTION:
Do not remove piston rod lock nut completely. If it is
removed completely, coil spring jumps out and may cause
serious damage or injury.
3. Compress coil spring using a spring compressor (commercial
service tool).
CAUTION:
Be sure spring compressor is securely attached to coil spring. Compress coil spring.
4. After making sure coil spring is free between upper and lower seats after Step 3. Remove piston rod lock
nut.
5. Remove small parts on strut.

Remove strut spacer, strut mounting insulator, strut mounting insulator bracket, spring upper seat,
upper rubber seat, and bound bumper. Then remove coil spring from strut.
6. Gradually release spring compressor, and remove coil spring.
INSPECTION AFTER DISASSEMBLY
Strut

Check strut for deformation, cracks, and damage, and replace if necessary.

Check piston rod for damage, uneven wear, and distortion, and replace if necessary.

Check welded and sealed areas for oil leakage, and replace if necessary.
Insulator and Rubber parts.

Check strut mount insulator for cracks and rubber parts for wear. Replace them if necessary.

Attach bound bumper, upper rubber seat, spring upper seat,
strut mount insulator and strut spacer. Position piston rod lock
nut.
CAUTION:
Do not reuse piston rod lock nut.
3. As shown in the figure, set spring upper seat. “ ” Mark on it
should face outside of vehicle.
4. Be sure coil spring is properly set in upper and lower rubber
seats. Gradually release a spring compressor (SST).
CAUTION:
Be sure upper and lower rubber seats are properly aligned
to strut, coil spring, and spring upper seat.
5. Tighten piston rod lock nut to the specified torque.
6. Remove strut attachment (SST).SEIA0127E
