Lincoln Navigator
Having 1998-2002 Lincoln Navigator Air Suspension Problems? You should consider a Navigator Air Suspension Conversion Kit? Do you trust your aging vehicle on the road with the old, worn out air suspension system? Being that it's almost impossible to drive a Lincoln Navigator with a malfunctioning air suspension system, nip those problems in the bud NOW by removing that system BEFORE it puts you and your family on the side of the road! Easily remove the stock air system and replace it with a tried and true Suspension Conversion Kit from American Air Suspension. Remember....there's nothing more reliable than a steel coil spring.
This 4x4 1998-2002 Lincoln Navigator Suspension Conversion Complete Kit comes with ALL parts needed to do the suspension conversion, including Premium Rear Coil Springs, Front Coil-Over Shocks, Rear Monroe Sensatrac Shocks......as well as instructions to do the install and to defeat the Check Suspension message.

Other Available Kits

Most 4x4 Expedition & Navigator owners don't realize that there vehicle has front air suspension as well, but the front has a pair of special air shocks that assists the front torsion bars. While this of course is another potential leak area to worry about, the majority of the time, these air shocks need to be replaced before they start leaking "air"(these air shocks are over $125 each now) This is due to leaking hydraulic fluid from the shock that gets transferred into the air suspension system. When this happens, the hydraulic fluid attacks the rubber and swells it 2-3 times it's normal size. This wreaks havoc on ANY seal and eventually plastic. This can lead to multiple leaks at the line connections, which kills the efficiency of the system. In other words, instead of being able to pump up the vehicle in say....15 seconds, because it has multiple leaks in the lines it has to make up for, it's now taking 30-90 seconds! Another part that takes a huge hit from this is the compressor itself. The hydraulic fluid swells the seal in the vent solenoid so big that air can't physically get past the seal. This in turn shows up as the rear air springs staying high all the time and a constant air suspension message.

The worst part is, even if the leaking shock is replaced, unless the air lines are cleaned out with some sort of cleaner, the trapped fluid will continue to attack any compressor that's installed.

Are those Coil Over Shocks in the picture for the Front?
Yes, they're for the Front. The AW/D (4X4) Expedition & Navigator has air suspension in the front & the rear. While the rear is more well known as a leak problem with it's "air springs", the Front "air shocks" will eventually sag down too.....even if they aren't leaking. In other words, if you don't do a front conversion as well, the front WILL sag after a couple weeks or so.

What are some of the signs of Air Suspension Failure?
* Computer generated "Suspension Messages" or "Check Suspension" lights on while driving *
* Hearing the on-board air compressor run more than it used too and/or it's just louder that it was *
* Rear is down after sitting for awhile *
* Rear is stuck Jacked up *
* During cold temperatures, the car goes down and won't pump itself up *
* Hissing noise when weight is added to the vehicle *

What Could Be Wrong?
#1 Air Suspension Compressor
#2 Air Suspension Compressor Relay
#3 Sensors
#4 Module
#5 Front Air Shocks
#6 Broken Air Line Union

#7 Wiring Problem=$100-$150 per hour, until the problem is fixed
#8 Capable Mechanic that can diagnose system =Good Luck!
(we've found out only 1 in 20 mechanics know how to diagnose air problems)

Advantages of Converting to a Conventional Coil Spring Suspension?
#1) Converting to Coil Springs is like going back "Old-School". No magic, no mystery....just good old fashioned reliability. A solid Steel coil spring keeps you & your family from being stuck on the side of the road, rather than a 2mm thick piece of rubber and some air!
#2) Converting to Coil Springs Saves You Money Now & Later on! You'll spend a fraction of the cost to convert, but then....You're Done. No frequent trips to the dealer for them to "try" other parts trying to fix your air suspension.
#3) Our springs have a Lifetime Warranty. All our kits are made with Eibach springs, so matter how long you own your car, you're covered. As apposed to the air suspension, where if you keep the vehicle long enough....you'll have to do the same repair over again.
#4) One less thing in a High-Tech world to worry about. These newer cars with air suspension, with their compressor, rubber air bladders, multiple sensors, solenoids & miles of wiring, are great when they're new. The newness quickly wears off when you find out how much it's going to cost to keep the the factory system maintained.

Best thing?
The entire kit costs about the same as
1 replacement OEM Air Spring!

Lincoln Navigator 4x4 Air Suspension Conversion
Below are "Some" of the problems with Air Suspension

Having Lincoln Navigator Air Suspension Problems? Stay with the Air Suspension or Do an Lincoln Navigator Air Suspension Conversion with Sensatrac Shocks?

Lincoln Navigator Air Suspension Conversion Kit with Shocks 4x4 - Sensatrac

The picture below shows the the beginning of air suspension trouble. Early in the stages of a leak(6-8 months), the only time an old air spring will leak is while being driven down the road. During this 6-8 month time span, the owner drives his/her vehicle normally, unaware that the small leaks are overworking the vehicles air suspension system. Only after a part has failed, or the leak gets so bad that the compressor can't keep up anymore, does the owner actually "see" a problem. Again, by this time, it's already done damage to the system.

Dry Rotted Air Spring

Hot Weather:ALL air compressor produce moisture, no matter the size. Bigger air compressor like whats in an auto repair shop or in most shade-tree mechanics garages, fuel air tools, blow sawdust and air up tires. Although the bigger compressors produce more moisture than a smaller one, the bigger compressor with a tank also has a way to easily drain the moisture from the system.Most people don't realize that an automotive air suspension system is just like an air compressor in their garage with one big difference between them. Because of all the low lying air lines and other parts(air springs - air struts) in the vehicle, there is no way to easily drain moisture out of the system. A 1998,1999,2000,2001,2002 Lincoln Navigator Air Suspension Conversion with Sensatrac Shocks? With Premium Coil Springs, there is no difference in ride quality no matter how hot it gets!You've heard automobile air suspension systems have a dryer that absorbs the moisture? That is true, but keep in mind 2 things. #1) Having a dryer right off the air source is at best only 95% effective. The reason for this is because a rule of thumb when working with pneumatics, is to have the dryer or collector a good 6 feet from the source. This is to allow the hot moisture filled air, time to cool a bit where the dryer can grab it. Not allowing it to cool down a tad makes the whole drying system not as effective, because the moist hot air will blow right past the dryer. Short term(when the vehicle is new), you'll never have this problem, because the new dryer has collected most of the moisture and not enough moisture has collected in the system to cause problems.#2) The dealer won't tell you this, but because they want you to keep buying air suspension parts and to come line their pockets later on when your out of warranty, but most dryers used on these automobile systems only have a lifespan of 4-5 years. After this time has passed, the dryer pretty much turns into a collection point. In other words, instead of the moisture gel beads inside the dryer collecting the incoming moisture, the moisture is now just collecting in the dryer.....just sitting there. The moisture then plays a see-saw game of going back & forth from inside the lines & air springs - struts & back to the compressor. It makes its way back to the air suspension compressor, because most systems are designed to dry themselves by blowing air thats already in the system, back through the dryer & air suspension compressor. Whats bad about that? What happened to all that moisture that was built up and sitting in the dryer? That's right, its now being forced....by high air pressure....through the compressor! These air suspension compressor generally have an estimated 40% duty cycle, which is considered light duty in most cases. They are designed from the factory to run bone dry and will be permanently damaged from ANY moisture.What makes these facts even worse? If an air suspension compressor produces moisture normally anyway, what does it do when it has to run 2-10 times more because of a leak in the air springs? Answer: Its going to make 2-10 times more moisture than it would normally!In other words, even if you spend $400-$900(not including labor) for another air suspension compressor, the moisture that has collected in the rest of the system all those years, that's still in there, will quickly attack & overwhelm the new dryer and then damage the replacement air suspension compressor!How long the replacement compressor lasts greatly depends on 2 things:1: How much it has to run = If the leak(s) in the system was repaired.If the leak(s) were repaired, you may have a chance. If not, the 40% duty cycle air suspension compressor thats made to run 2-10 times more than it was designed, will continue to run constantly until the small plastic parts(all of them have 'em) inside them start to melt. Running constantly is also hard on bearings and even armatures, due to the increased amperage draw from swollen(from moisture) parts(rings) inside.2: How much moisture was in the system. Over the years, we've experienced new $500+ factory air suspension compressor damaged to the point of not working at all, in less than 1 months use....due to excessive moisture in the system alone!A 1998,1999,2000,2001,2002 Lincoln Navigator Air Suspension Conversion with Sensatrac Shocks? With Premium Coil Springs & Brand Name Premium Struts, there is no difference in ride quality no matter how much moisture is in the air! Cold Weather: One reason air suspension problems seem to show their ugly heads when it gets cold on air suspension equipped vehicles, is because the rolling lobe type air springs used on these vehicles get harder and less pliable the colder it gets.The rubber air bladder on these air springs are only 2mm thick and can't seal themselves as effectively when the rubber is hard(cold).ANY business selling air suspension parts would make way more money if you stayed with the air, as you will continually buy parts for it.While the air suspension system doesn't produce much moisture in colder weather, the collected moisture in the system does hurt system performance. When the moisture that is in in the dryer drops below freezing, the dryer can easily become a solid block of ice, not allowing ANY air to travel in any direction! This means no load leveling when weight is added, but also not venting the air after the weight is removed! Say you were lucky enough to have the air suspension compressor squeeze enough air pressure past the solid block of ice in your 10+ year old dryer. You take your car and drop someone off. NOW, the system can't relieve all the extra air in the system and you drive around looking like a 4x4.A 1998,1999,2000,2001,2002 Lincoln Navigator Air Suspension Conversion with Sensatrac Shocks? With Premium Coil Springs, there is no difference in ride quality no matter how cold it gets!Recommendation?With all this being said, our recommendation would be to do away with the air suspension system completely and do an 1998,1999,2000,2001,2002 Lincoln Navigator Air Suspension Conversion with Sensatrac Shocks on your vehicle. Its a simple, straight forward repair and is the ONLY way that you'll be able to rely on this vehicle!
