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:
