The 2003-2004 Lincoln Navigator is built with the following suspension components: 2003-2004 Lincoln Navigator Air Struts (x4)- The hydraulic fluid-filled struts connect to each wheel and contain a perch upon which rests an air spring. Instead of a mechanical spring, these "air springs" use pressurized air to hold the vehicle off of the wheels and cushion the ride. These air sacks are by far the leading cause of all air suspension leaks. The hydraulic portion of the struts themselves help dampen vibration and control ride ride quality by reducing bounciness. If the vehicle has over 80,000 miles, it is likely the hydraulic strut itself is worn out, too. 2003-2004 Lincoln Navigator Height Sensors (x4)- These small linkages can be found next to each wheel of your Navigator. They are constantly monitoring the height of the vehicle at each wheel and sending that information back to the suspension control module. These components are one of many in air suspension that inevitably wear out with age. 2003-2004 Lincoln Navigator Air Lines- These tubes transfer pressurized air from the compressor to the air springs. This air is what is used to inflate the air springs and hold the vehicle up off of its wheels. 2003-2004 Lincoln Navigator Solenoids (x4)- These L-shaped plastic components work together with the suspension computer to regulate the air pressure in each air spring on your Navigator. As they get older, they will start to leak, causing other components in the air suspension to pick up the slack andstart to deteriorate much more quickly. 2003-2004 Lincoln Navigator Compressor- The air in the air springs is generated by the compressor using mechanical force. This compressor also pumps that air into the rest of the system. Once components like the solenoids or air springs start to leak or fail, the compressor usually responds by working harder. This will, in turn, lead to early failure of the compressor, one of the most expensive components in an air suspension. 2003-2004 Lincoln Navigator Dryer Assembly- The dryer is essential to the health of the air suspension system. It removes moisture, which can damage the air suspension components from the inside out. It is usually replaced along with the compressor. 2003-2004 Lincoln Navigator Suspension Control Module- This small computer manages the diagnostic functions of the air suspension system and also uses information from the ride height sensors to maintain your Navigator's correct ride height. 2003-2004 Lincoln Navigator O-rings- These rubber o-rings maintain the seals where the air lines connect. This ensures that the system is both clean and efficient. They should be replaced whenever the air suspension is serviced.
Suspension Failure Signs
Be on the lookout for common signs of a failed or leaking air suspension in your 2003-2004 Lincoln Navigator. The most obvious of those is a sudden drop of three to five inches of ride height in any of the wheels or noticeable difference in ride height between different sides of the Navigator. You may experience sagging in the rear or front or an overall appearance of the Navigator squatting down lower than usual. These are all tell-tale indicators of suspension failure. When this occurs, it's common for the air compressor to cease working or run way too often (it will be loud and noisy). Other components may wear out. Your Navigator's ride height should remain consistent. If it looks like it's been slammed to the ground, it's well past time for a repair. This situation is not only uncomfortable, it is outright dangerous. Don't waste time getting your suspension repaired.
