2007-2013 Lincoln Navigator EL Rear Suspension Conversion Kit (FU3RB)

Replaced Components
The 2007-2013 Lincoln Navigator EL is built with the following suspension components: 2007-2013 Lincoln Navigator EL Air Struts (x2)- traditional struts that use a rubber air spring in place of conventional steel coil springs. Also known as air bags, the air springs are made of plastic and rubber bag and use pressurized air to support the weight of the vehicle. Cracks develop in the rubber air springs with normal wear and tear and these are the number one cause of all air suspension leaks. All air struts go bad at about the same rate, so if one is leaking, the other one will not be far behind. For a proper repair, both need to be replaced at the same time. 2007-2013 Lincoln Navigator EL 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. 2007-2013 Lincoln Navigator EL Solenoids (x2)- This vehicle is equipped with 4 solenoids. These plastic components connect the electrical connection and lines of suspension components to the suspension control module. The solenoids are responsible for regulating the air pressure in each air spring or air shock. Solenoids are a small piece of the suspension system but they play a big role in how well it functions. If a solenoid is not working properly, it will cause the vehicle to be unlevel and, in turn, cause the compressor to burn out. 2007-2013 Lincoln Navigator EL Compressor- This vehicle is equipped with one air suspension compressor. The compressor is responsible for pumping up the air springs and shocks. When the air suspension starts leaking, the compressor is forced to run continuously to try and keep the air springs inflated. After a couple of days of running non-stop, the compressor will burn itself out. Replacing the compressor is a timely and expensive project to undertake. 2007-2013 Lincoln Navigator EL Dryer Assembly- This vehicle is equipped with a dryer assembly. The dryer assembly is responsible for getting moisture out of the air lines. Once the air suspension parts start to leak, moisture will build up throughout the air system. Moisture damages the air suspension components from the inside out. The dryer must be replaced whenever the compressor is replaced to prevent further damage. 2007-2013 Lincoln Navigator EL Suspension Control Module- This vehicle is equipped with a suspension control module. This module is the brain of the suspension system and it reads all of the signals that are being sent by the height sensors and determines if the vehicle needs to be raised or lowered. 2007-2013 Lincoln Navigator EL 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
Your 2007-2013 Lincoln Navigator EL has had a great run, but eventually the air suspension system will fail.  That’s probably why you are on this page. There are a few distinctive symptoms to look for on your Navigator to help you diagnose whether or not the suspension is leaking or failed. One obvious sign of suspension total failure is a major difference in ride height between the front and back of the Navigator. Many drivers describe their Navigator as looking like it is “squatting” down, losing about three to five inches of ride height in the rear. Another common symptom is an illuminated suspension warning message or light on the instrument panel. If your suspension is going bad, the air suspension compressor might be running too long (longer than 15-20 seconds max) or not working at all. Other components will begin to wear out, so you want to get your suspension fixed ASAP. Check your rear air springs for visible cracks -- but keep in mind there may be leaks not seen without taking the units off the vehicle.

OEM Replacement Cost
'+ Air Struts ($820/each) + Compressor and Dryer Assembly ($720) = TOTAL: Over $2,400 (and that doesnt even include replacing electronic components that are known to fail such as the height sensors).

Aftermarket Replacement Cost
'+ Rear Air Strut Assemblies ($799/pair) + Compressor ($200) + Dryer Assembly ($40.00) = TOTAL: Over $1,000 (and that still doesn't include replacing electronic components that are known to fail such as the height sensors).
