Disassembly Procedure

  1. Remove the front suspension strut assembly from the vehicle. Strut Assembly Removal and Installation 
  2. GM4968397
    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.

    Place the front suspension strut assembly (3) into the CH-48845  compressor (1) securing the two lower compressor arms to the front coil spring lower coils.

    3. NOTE:

    The CH-48845-10  adapter is used to compress the front coil spring from the top of the front suspension strut mount to provide added stability and aid in compressing the front suspension strut to sufficiently release tension rather than using the CH-48845  compressor as a stand alone.

  3. Adjust the CH-48845-10  adapter (2) so that the opening of the adapter sufficiently captures the front suspension strut mount.
  4. Install and secure the CH-48845-10  adapter (2) to the two upper compressor arms of the CH-48845  compressor (1).
  5. Adjusting the CH-48845  compressor (1), remove any clearance between the CH-48845-10  adapter (2) and the front suspension strut mount ensuring that it is properly positioned as shown.
  6. Using the CH-48845  compressor (1), compress the front coil spring enough to remove tension from the upper strut mount.
  7. GM4968599
    NOTE:

    Before removing the strut rod mount nut, support the front suspension strut to prevent it from falling.

    Using the CH-49375  wrench (1), loosen the front strut rod mount nut.
