press coil spring between rubber seat and strut until coil spring
with a spring compressor is free.

CAUTION:

Be sure a spring compressor is securely attached coil
spring. Compress coil spring.

3.

Make sure coil spring with a spring compressor between rubber
seat and strut is free. And then remove piston rod lock nut while
securing the piston rod tip so that piston rod does not turn.

4.

Remove mounting seal, strut mounting bracket, rubber seat,
bound bumper from strut.

5.

After remove coil spring with a spring compressor, and then
gradually release a spring compressor.

CAUTION:
