Removal & Installation

If the vehicle is equipped with air suspension, the electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the luggage compartment. Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these operations. Failure to follow these instructions may result in personal injury.

  7. Remove the upper control arm center nut.
  9. Remove the stabilizer bar link nut and discard.
  11. Disconnect the brake line retainer.
  13. Remove the steering knuckle nuts and remove the steering knuckle.
