The 1997-2002 Lincoln Navigator (4WD) is built with the following front suspension components:
1997-2002 Lincoln Navigator (4WD) Air Shocks (x2) - the air shocks are pumped up automatically to keep the vehicle level and to assist with the ride quality. These shocks contain a rubber bladder which is notorious for dry rotting, causing leaks in the shocks which inevitably leads to multiple failures in the air system. These are located in the front.
1997-2002 Lincoln Navigator (4WD) Air Lines- tubes that run from a compressor to the air which carry pressurized air to the air bags in order to adjust the height of the vehicle, respectively.
1997-2002 Lincoln Navigator (4WD) Compressor Assembly- 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.
1997-2002 Lincoln Navigator (4WD) Torsion Bar- Adjustable horizontal bar on the front of the vehicle that holds the vehicle off the ground.
1997-2002 Lincoln Navigator (4WD) Dryer- prevents moisture build-up inside of air suspension parts.
1997-2002 Lincoln Navigator (4WD) Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle‚Äôs correct ride height.
