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.
Your mark viii has a air ride system. and as you drive, it has a pump under the hood. well over night it leaks down. then when you crank the engine .this pump will come on and air up the air ride system.kind of like a tire.But if just the front goes down ,Then you have a leak at the 2 front bags or lines, or connections. to find the leak try some soap in a spray bottle. after the bags are fully aired up and the engine off.some Lincolns leak worse the way they sit. it could leaking in a few places,that is what the soap is for.you can buy every part for that system from, Air Suspensions out of Orlando FLA 1-800-251-8993.plus diagrams
You have an air suspension and the bags only last 8-9 years on average-they are not too hard to replace, and you can usually find them for $200 each new, and $100 used if you look around-but first to see what side is leaking, open the trunk and shut off the suspension compressor and let the car sit, see if one side is lower than the other. The low side is the one with the leak, and you can usually get away with replacing just that one to get you by until you can do the other side. It may not drop in which case your solenoids are causing the leak (mine does this) and I just shut mine off when I am parking it and leaving it for a longer period of time (0vernight, days even) and mine will not drop if I do this-means I have a leak that the controller vents in a solenoid when I shut it down. You can also trash the whole system and put in conventional springs, about $400 front and back and then you'll never have the problem again, but most people who do this hate the ride (and love the dependability).
Sounds like the front "air ride suspension" is out.
That works off rubber bags built into the springs. If one or both has developed a leak/hile, it lets the front end (or rear or both) drop to ride on the bottom of the suspension.
Get the wallet out. It's expensive.
Sorry :-(
Experienced problem after problem with my suspension on my 1990 LSC. Finally contacted "Strut Masters" online and replaced my entire system with a conversion for less than 400 and an afternoon. Installation was simple.
leaks can be difficult to find in these systems. They could be in the air springs themselves, the air lines etc... not to mention you could have a ride height sensor that is malfunctioning or the control module. A lot of people are converting these old cars from the air ride suspension system to a standard passive coil spring conversion. A high quality, powder coated, American steel coil spring is DESIGNED to last the LIFETIME of the vehicle. http://www.strutmasters.com offers conversion kits with a lifetime warranty so youwon't have to worry about your suspension again. Give them a shot.. it definately beats the dealer price of around $1200 to fix your air ride.
