    CAUTION: When installing the strut attachment (SST) to strut assembly, wrap a shop cloth around strut assembly to protect it from damage.
  2. Install lower rubber seat to strut assembly.
  3. Compress coil spring using a spring compressor (commercial service tool), and install it onto strut assembly.
    CAUTION:
    • Face the tube side of coil spring downward. Align lower end to spring seat as shown in Fig 2 .
    • Be sure spring compressor (commercial service tool) is securely attached to coil spring. And then compress coil spring.
