  5. Loosen the bolt that attaches the LH rear lower aft link to the subframe.
    Tip
    Use of the following tool(s) is recommended:
    • 21 mm socket
    • 21 mm combination wrench
  6. Install a spring compressor onto the LH rear suspension spring:
    Warning
    Springs in a compressed state are under large amounts of energy. Refer to the Tool Profile for the spring compressor kit prior to performing this step for additional warnings and cautions.
  7. Position support stand underneath LH rear lower aft link.
  8. Remove bolt securing LH rear lower aft link to knuckle.
  9. Remove bolt securing LH damper to rear lower aft link.
  10. Hold the LH rear suspension spring while slowly dropping the support stand to release the LH rear lower control arm from the knuckle.
    Note
    Attach a bungee cord from the LH lower control arm to the spring to assist with the removal process, if needed.
  11. Remove spring compressor from LH rear coil spring.
  12. Remove the LH rear suspension spring from the vehicle.

Install

  1. Position the new LH rear coil spring onto the lower aft link.
  2. Install spring upper and lower isolators.
  3. With an assistant, install the LH rear coil spring onto lower after link.
  4. Install the LH rear suspension spring into position while raising the support stand until the LH rear lower control arm is supported.
    Note
    The LH rear suspension spring might need to be compressed further until the LH rear lower control arm and knuckle holes align.
  5. Raise lower aft link with support stand.
  6. Position the LH rear damper on the LH rear lower aft link, and then install and hand-tighten the bolt. Do not torque the bolt at this time.
  7. Position the LH rear lower aft link on the LH rear knuckle, and then install and hand-tighten the bolt. Do not torque the bolt at this time.
  8. Remove support stand from LH rear suspension.
  9. Remove the bolt that attaches the LH rear brake rotor to the hub.
    Note
    Use of the following tool(s) is recommended:
    • Cordless Ratchet/Impact Driver

  10. Install the hub jack adapter onto the LH rear hub and hand-tighten the lug nuts (x5).
  11. Position and raise the underhoist stand to simulate the suspension at ride height.
  12. Adjust the underhoist stand and/or spring compressor until the lower beam of the rear ride height torque tool rests against the bottom edge of the lower aft link, as illustrated.
  13. Measure the distance between the bottom of the quarter panel and the center of the rear axle to make sure that the rear suspension is set to ride height. The distance should measure 428 mm.
  14. Torque the bolt that attaches the LH rear lower aft link to the LH rear knuckle.
