Question about 2003 Lincoln Navigator

Where are the leveling sensors located on a 2003 Navigator?

Started having problems with suspension. Should I continue changing out old with new, or change it all with springs?

    I have a 2003 Lincoln Navigator with a suspension problem, two days ago everything was fine now the left side of the vechile is raised higher than the right side. The compressor for the suspension seems to be working ok. The right side goes up and down normally, but the left side does not move.
    Is there a way to manually let the air out of the suspension with the vehicle off? Then when the vechile is on let the compressor pump it back up?

There is one at each wheel. here is some info

Vehicle Dynamic Suspension The four wheel air suspension system is comprised of the following components:

  • service switch
  • control module
  • two front height sensors
  • one rear height sensor
  • compressor and drier assembly (includes vent solenoid)
  • air lines
  • front and rear air spring and shock absorber assemblies
  • four air spring solenoids
Where are the leveling sensors located on a 2003 N - s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: The service switch for the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the jack storage area in the rear of the passenger compartment. Failure to do so may result in unexpected inflation or deflation of the air springs which may result in shifting of the vehicle during these operations.
s3j~us~en~file=ani_caut.gif~gen~ref.gif WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.

I Would go with springs. I understand people enjoying the air ride but I promise it is more trouble than it is worth. Compressors have a 100% failure rate. What will happen is the airbag will end up getting a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag kills the compressor and you have to parts you have to constantly keep buying. With air suspension there is never a permanent fix. I would recommend going to strutmasters.com and taking a look at the conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is [U][B]guaranteed[/B][/U] to last the life of the car. And for a very affordable cost. I added the link below so you can check it out. http://www.strutmasters.com/lincoln-suspension-parts-s/1.htm I hope I was of some help Good Luck!!!!

Can the front suspension problem be due to the compressor


If the rear suspension is not affected its probably a leak or a front height sensor.

2000 navigator: sit higher on one side than the other.


the air ride suspension has level sensors under the vehicle, one of the sensors must be bad making the truck deflate the airbag or inflate it too much. you may need to have someone with a scan tool to access the air suspension module and check for fault codes. you can try turning the air suspension switch off for about an hour to see if the system will reset. the switch is located under the dash on the right side kick panel.

2004 Lincoln nave, rear wheels jacked up high, front wheels normal, rides real rough??? any thoughts???? Thanks,


Replace the air suspension with conventional shock/strut
conversions. The Air Ride System is not worth investing
time and money ,after the vehicle is 5 years old.
Too expensive to maintain ,and too difficult to diagnose

Next time buy the Ford version of the vehicle

Suspension Leveling System Problem for 1998 Lincoln Navigator


Hi :-)
I don't know how will this help, but you can check the car in the morning before you start it, look under it and check the level, is it dropped from the front or back. this way you can tell if you have a leak and where. if not then i think its the level sensor. in the 1998 you have two one in the front left. and one near the deferential in the back.

hope this helps you in anyway.
have a nice day.
