2. Remove the front coil springs from the strut assembly following the Repair Manual procedures.
3. To ensure good adhesion of the pressure sensitive glue on the inner surface of the insulator, clean the spring with a suitable solvent in the area where the insulator is to be installed.
4. Protect the shaded portion of the coil spring using the cut length of the coil spring insulator (see Figure 2).
