Warning

To prevent personal injury and/or component damage, use the proper tools to support and compress the coil spring prior to removal of the strut shaft nut when removing the coil spring. The coil spring is under extreme pressure and can become a projectile should the spring separate from the strut before all of the tension is relieved.

Warning

Use only the CH-48845 Spring Compressor when servicing suspension components on this vehicle. Other tools may not be strong enough for the springs on this vehicle and you could be injured if you do not use Special Tool CH-48845. Failure to do so could result in serious personal injury.

Note

ONLY use hand tools to perform the following service procedure.

1. Place the front shock absorber (3) into the CH-48845 Strut Spring Compressor (1) securing the two lower compressor arms to the front coil spring lower coils.

Note

The CH-48845-10 Strut Spring Compressor Bridge Adapter is used to compress the front coil spring from the top of the front shock absorber mount to provide added stability and aid in compressing the front shock absorber to sufficiently release tension rather than using the CH-48845 Strut Spring Compressor as a stand alone.

2. Adjust the CH-48845-10 Strut Spring Compressor Bridge Adapter (2) so that the opening of the adapter sufficiently captures the front shock absorber mount.
3. Install and secure the CH-48845-10 Strut Spring Compressor Bridge Adapter (2) to the two upper compressor arms of the CH-48845 Strut Spring Compressor (1).
4. Adjusting the CH-48845 Strut Spring Compressor (1), remove any clearance between the CH- 48845-10 Strut Spring Compressor Bridge Adapter (2) and the front shock absorber mount ensuring that it is properly positioned as shown.
5. Using the CH-48845 Strut Spring Compressor (1), compress the front coil spring enough to remove tension from the front shock absorber mount.
