1984-1992 Lincoln Mark VII (7) Front Air Suspension Conversion Kit (FF1F0)

Replaced Components
The 1984-1992 Lincoln Mark VII is built with the following front suspension components:

1984-1992 Lincoln Mark VII Air Springs (x2)- commonly referred to as air bags, a plastic and rubber bag that is fitted on top of the strut that uses pressurized air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These are the number one cause of all air suspension leaks. All air springs all go bad at about the same rate. If one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time.

1984-1992 Lincoln Mark VII Shock Absorbers (x2)- metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.

1984-1992 Lincoln Mark VII Height Sensors (x2)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

1984-1992 Lincoln Mark VII Air Lines- tubes that run from a compressor (air suspension) to the air struts which carry pressurized air to the air bags components in order to adjust the height of the vehicle, respectively.

1984-1992 Lincoln Mark VII Solenoids (x2)- usually either L-shaped or straight, these plastic components connect the electrical connection and lines of suspension components to the suspension control module on vehicles with active suspension. The solenoid regulates the air pressure for each air spring. Solenoids start to leak as they wear out causing the vehicle to sag or to lean. This will cause the ride height sensor to send a signal to activate the compressor in an attempt to inflate the air suspension and level out the vehicle. This excessive work load will eventually lead to total failure of the compressor.

1984-1992 Lincoln Mark VII Compressor- creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.

1984-1992 Lincoln Mark VII Dryer Assembly- used to keep moisture out of air lines and air springs in order to prevent freezing and internal cracking of these parts. Once air suspension starts leaking, moisture will build-up throughout the air system. Moisture damages the air suspension from the inside. The dryer will need to be replaced in order to eliminate the moisture and prevent any further damage.

1984-1992 Lincoln Mark VII Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicles correct ride height.

1984-1992 Lincoln Mark VII O-rings- although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.



Suspension Failure Signs
There are warning signs that the air suspension system on your 1984-1992 Lincoln Mark VII (7) is leaking or has failed, and these signs should not be ignored if noticed. If a bad suspension is left to run for too long without being fixed, total failure could set in. All vehicle components can wear out, rendering the Mark VII immobile. The most noticeable sign is a sudden uneven height difference between different sides of the Mark VII. This could look like a lean from one side to the other. There could be one overly sagging side while the other side looks inflated. The rear end could be sagging, making the Mark VII look like it’s squatting down low to the ground. If the Mark VII is not meeting and maintaining the proper ride height, you may be looking at a costly suspension repair or replacement. Look at the instrument cluster- is there an illuminated suspension warning light or message? If so, don’t ignore it. Listen to the air compressor- is it too loud and noisy? It might be running too often. Has it stopped working completely? A bad suspension has caused it to wear out.
