A common problem is for the shocks to blow out when the compressor is not turned off when lifting on the Lincolns.
Or, over time leaks develop, or the air pump goes bad.
Removal & Installation
The use of a diagnostic scan tool capable of inflating and deflating the air springs will be necessary to perform this procedure.
Do not remove an air spring under any circumstances while there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.
To prevent vehicle damage or personal injury, do not install an air spring that has become unfolded.
Observe the following when servicing the air spring suspension system.
- Any air spring which is unfolded must be refolded prior to being installed in the vehicle
- The air spring refolding should only be used for an air spring which has never supported the vehicle's weight while in the incorrectly folded position
- Do not attempt to inflate any air spring which has been collapsed while un-inflated 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 scan tool
- Always inspect an air spring for the correct shape after inflating it
- Before servicing the vehicle, refer to the precautions in the beginning of this section.
- Position the vehicle on a hoist with the tires slightly above the floor.
- Release the pressure from the air spring using a suitable scan tool.
- Raise the vehicle to gain access to the air springs.
- Remove the retainer at the top of the air spring.
- Detach the air spring from the rear axle.
- Disconnect the electrical connect and the air line.
- Remove the air spring from the vehicle.
- Position the upper end of the spring on the frame and install the retainer.
- Install the bottom end of the spring on the axle housing.
- Connect the air line and the electrical connector.
- Lower the vehicle until the tires are slightly above the floor.
- Inflate the air spring with the scan tool.
- Lower the vehicle to the floor.
