    *Removal Warning & Notice:

      Vent all air pressure from the air suspension system prior to disconnecting or removing any air suspension components. It is dangerous to remove air suspension components while under pressure. Failure to follow this instruction may result in serious personal injury. 

      Any air spring which is unfolded must be refolded prior to being installed in a vehicle. Refer to the procedure. An incorrectly folded air spring could rupture, altering the handling characteristics of the vehicle. If a vehicle has been driven with an incorrectly folded air spring, a new air spring must be installed. Failure to follow these instructions may result in serious injury to vehicle occupant(s). 

      Failure to observe the following instructions may result in a sudden failure of the air spring or suspension system.
      Any rear spring which is unfolded must be refolded prior to being installed in a vehicle.
      The air spring refolding procedure should only be used for an air spring which has never supported the vehicle's weight while in the incorrectly folded position.
      Incorrectly folded air springs found on vehicles during pre-delivery inspection or after use must be installed new.
      Do not attempt to inflate any air spring which has been collapsed while uninflated from the rebound hanging position to the jounce stop.
      When installing a new air spring, care must be taken not to apply a load to the suspension until springs have been inflated using the air spring fill procedure.
      After inflating an air spring in the hanging position, it must be inspected for correct shape.
    1.NOTE: The vehicle must be positioned on a suitable lifting device prior to deflating the air suspension system.
    With the vehicle in NEUTRAL, position on a hoist until the wheel and tire assemblies are slightly above the ground. 
    2.Using the scan tool, vent the air springs.
    3.Remove the air spring retainer.
    4.Detach the air spring from the rear axle.

    5.Remove the air spring in the following sequence.
