Lincoln vehicles have a self-leveling suspension system that uses air pressure to ensure each corner of the vehicle sits in the proper position. When an air line -- another component of a Lincoln air suspension system -- becomes damaged, You must remove and replace it to keep the suspension working correctly. The air line connections used by Lincoln employ a quick-release system that uses a ring and a brass fitting to secure the air line to the shocks, solenoid and pump providing air for the system.
Move the Lincoln to a hard, level work surface. Set the parking brake. Open the trunk, and locate the air suspension switch. Turn the switch to the "Off" position.
Set one wheel chock in front of each of the vehicle's front tires. Set a floor jack at an approved lifting point at the back of the vehicle. Pump the floor jack to raise the rear tires of the Lincoln off the ground. Place one jack stand under the frames, directly in front of each rear tire. Lift and support the front of the vehicle.
Clean the connecting point between an air line and another component of the air suspension system by wiping around the air line with a clean rag.
Push the red or orange collar -- sitting at the point the air line meets the suspension component -- toward the connection. Pull the air line away from the connection. Repeat the process to disconnect the other end of the air line from the suspension.
