2000 navigator: sit higher on one side than the other. replaced both air springs, front air struts, compressor, levelers, compressor relay. now the passenger side sits about two inchs higher than the driver side. is there a computer setting to unjust the hieght or pressure?

The most common issue is that you need to replace the air springs, they are leaking, very common on older Navigators.

Time to trade it in.

they are struts and you will need a strut spring compressor to disassemble them. will need to align the car after install new struts.BE VERY CAREFUL THE COIL SPRINGS CAN COME LOOSE FROM THE SPRING COMPRESSOR!!!!!

Try this from my previous post....

Have a similar problem... My 2003 Lincoln Navigator was manufactured May 22, 2003 so it's the late model that came with the Intec 5.4 Liter DOHC V-8 (not the Triton engine).

I replaced the two front ride height sensors (one for each air strut) and replaced the one rear ride height sensor that controls the ride height for BOTH rear air struts. (Yours may have one ride height sensor for each of the rear air struts.) That solved the problem for a few months during the warm months, until the weather started cooling off. Then back to the same issue.

The front passenger air strut started releasing air from the solenoid (air block) making a "hissing sound." Replaced BOTH front air strut solenoids (connected at the top of each air strut). That also resolved the problem for a few days. After going all around the world, I discovered it's the Air Ride Control Module (ASM) that was the problem all along.

This is most likely the culprit for your air ride suspension problem.

Check your rear suspension. Load-leveling air suspension struts could be bad or leaking. Air suspension compressor could be inoperative. Air suspension compressor relay could be bad. Air lines from compressor to struts could be leaking, from cuts, cracks, or having rubbed through against the frame. Transverse leaf spring could be sagging.
And it's Toronado, not Tornado. Sacrilege!

The struts model (MacPherson Strut),are both in front and back of this car.

Of course this is only the cartridge, you have to transfer the spring, and the top mount of the existing strut. You need a pair of coil spring compressor to do the job. The basic procedure to replace a strut is:
Remove the top nuts that secure the strut assembly to the frame mount inside the engine compartment. Do not remove the center nut.
Mark the lower strut mounting location on the hub for installation reference. The alignment will be close if the new strut is installed in the same position.
Remove the bolts that hold the strut assembly to the hub.
Remove the strut assembly from the vehicle.
Mark the top mount for installation reference. Using a side mounted spring compressor, compress the spring and remove the top nut and retaining washer. Pull strut assembly out from the bottom of spring.
Slide the new strut assembly up into the spring and reposition the top mount onto the spring in the same position that it was removed. Install the retaining washer and top nut.
Tighten the top nut to the manufacturer's specifications and carefully remove the spring compressor.
Place the strut assembly back into the vehicle.

Raise the car and remove the wheels. Loosen the bolts holding the strut to the steering knuckle. Before removing them, remove the strut mount bolts under the hood. Then remove the other bolts, the entire strut assembly will slide out. You can either install a complete new strut and spring assembly (more expensive), or you can use a coil spring compressor to remove the spring from the old strut and install it on a new one (less expensive but you must have access to a spring compressor). Make sure when installing the spring that it is aligned correctly on the new strut. A compressed spring is very dangerous, be sure to follow the instructions with the spring compressor. Re-install the strut assembly. Make sure that the knuckle bolts are torqued to spec.

I had the same problem with my 95 continental. what I did was ordered a conversion kit and replaced all air suspension with aftermarket strut and springs ...kit costed me $500 and I did the work...car rides at level hight all the time now
