How Do I know If My Navigator Air Suspension is failing?

There are common signs of a failed and/or leaking air suspension in your 2003-2006 Lincoln Navigator. The most noticeable is a sudden uneven height difference between different sides of the Navigator. This may look like sagging, perhaps from front to back, or leaning, from one inflated side to the other. Sometimes, the entire Navigator looks like it’s squatting down lower than usual. If your Navigator is no longer reaching and maintaining its appropriate ride height, it might have a bad suspension. Other signs to look for include: a suspension warning light or message on the instrument panel, or a non working air compressor (not working at all, or too noisy and overworked). You will want to repair your suspension ASAP before other components on the Navigator wear out. Worst case scenario- you may need a replacement if you have suspension total failure.

Suspension Components List

The 2003-2006 Lincoln Navigator is built with the following suspension components:

2003-2006 Lincoln Navigator Air Springs (x4)- commonly referred to as air bags, a plastic and rubber bag that is fitted on top of the strut that uses pressurized air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These are the number one cause of all air suspension leaks. All air springs all go bad at about the same rate. If one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time.

2003-2006 Lincoln Navigator Struts (x4)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.; the air spring assembled on top of the strut is commonly referred to as an air strut.

2003-2006 Lincoln Navigator Height Sensors (x4)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

2003-2006 Lincoln Navigator 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.

2003-2006 Lincoln Navigator Solenoids (x4)- usually L-shaped, these plastic components connect the electrical connection and lines of suspension components to the suspension control module on vehicles with active suspension. The solenoid regulates the air pressure for each air spring. Solenoids start to leak as they wear out causing the vehicle to sag or to lean. This will cause the ride height sensor to send a signal to activate the compressor in an attempt to inflate the air suspension and level out the vehicle. This excessive work load will eventually lead to total failure of the compressor.

2003-2006 Lincoln Navigator Compressor- creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.

2003-2006 Lincoln Navigator Dryer Assembly- used to keep moisture out of air lines and air springs in order to prevent freezing and internal cracking of these parts. Once air suspension starts leaking, moisture will build-up throughout the air system. Moisture damages the air suspension from the inside. The dryer will need to be replaced in order to eliminate the moisture and prevent any further damage.

2003-2006 Lincoln Navigator Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

2003-2006 Lincoln Navigator 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.

It’s been about 3 weeks now since I installed the conversion kit on my Navigator. I did it myself in my driveway. It was relatively simple, however I do not recommend doing this without a friend. It was a little difficult to do on my own with *limited* tools. Took me about 7 hours with a few issues that slowed me down. With a friend and the proper tools this can be done in less than four hours I’m sure.

The ride has significantly improved since day 1 of the install now (pretty stiff before they settle). It is a great ride now, it’s not as quiet as the air ride, but I can’t even hardly notice a difference in ride quality. Now I never have to worry about my failing compressor and the time it would take to air up my suspension, or the few times my fronts were riding on the bump stops.

I highly recommend anyone contemplating this kit buy it and get it done before your air ride inevitably fails.

“Very good service from the representative that I spoke with on the phone. Parts arrived in a couple of days, very nice service for ground delivery. The only problem, is one of the boxes arrived open, hopefully nothing fell out thanks. Parts going on this weekend. Thanks”

“Just bought this my 2005 Navigator. MAN WHAT a DIFFERENCE. Can’t believe how awesome my Navi rides. I love the piece of mind of not worrying about my air ride and the red springs look cool. Thanks Strutmasters!”

“Dear Web Master,

I really appreciated the help I obtained from your technician, Lou. He fully explained the product and assured me that I would have no trouble finding a mechanic to make the install. The repair quote for replacement of the air suspension system on my Nav was over $3000 from Tires Plus, and finding your company and the conversion kit is a godsend. Thanks!


Name: | Location: Houston, TX United States | SKU: FX24F

I have had four suspension problem betwen two navigators. All cost over 1,500. This last one (busted airbag) the truck was out of warranty. Thank God I found Strutmaster. I wasnt sure how easy it would be to install. IT WAS A BREEZE! At first I went to rent an impact wrench and air compressor from my local hardware store but I took it back. All I need was my sockets (15mm,19mm,29mm,30mm) a few wrenches and a rented breaker bar. I save alot of money on parts and on labor. Now Im trying to see if i can contract with a local repair shop to make some money doing these repairs for customers! If your truck is still in warranty take it to the dealer and make them pay to fix this BS. But if it is not STRUTMASTERS is the truth! the only way to roll. P.S. I love the red color hehehe

I purchased the 4 wheel air suspension conversion to coil kit. First off, it’s a much bumpier and louder ride. I could feel every single small bump, even the lines that make up the lanes. All these people who wrote it rides the same or it rides just like their air suspension did are crazy. My expedition on springs rides much smoother and handles better than these kits on my Navigator. I’m going to sell this kit and buy air suspension again. It’s a good cheap option, but if you can afford it replace with air suspension. I had mine professionally installed at Lincoln/Ford dealership. All other components in great working condition on my vehicle.

I have waited a few months before writing a review on the 4-Wheel Air Suspension Conversion Kit with eibach springs the truck does sit a little higher but not much still looks great in my opinion the truck rides much better than with the air ride it handles corners 100 times better not as much body roll goes over speed bumps and dips better not as bouncy would recommend this kit

Name: | Location: Rockaway Park, NY United States | SKU: FX24F

I have always wanted a LINCOLN NAVIGATOR and this year i finally was able to get one. A 2003 with low mileage and a price to good to be true. Made the purchase no problems, after driving for about a month it happened the whole truck leaned to one side then the front end dropped and would not raise back up. I said to myself thats why i got the truck so cheap!!! But i did my research and found the best company in world STRUTMASTERS.COM. Bought the conversion kit and installed yesterday and I’m driving BABY I’M DRIVING. Thank you so much and GOD BLESS.

Name: | Location: Houston, TX United States | SKU: FX24F

“Thanks Strutmasters! Great product! Easy install! I think the only thing that can be improved on this otherwise perfect product is if there was a way to list the size sockets will be needed for the
install. But not a big deal at all. And I love Strutmasters. I will be referring people! ”

Hello, I was really satisfied with my purchase. I ordered the part in the morning and it was shipped that day (as promised). I got emails giving me a status of the item. I would’ve given you an excellent review, but I just found out that I have to buy some sort of module to get rid of the message on my dashboard. I was told that since I am a current customer, I would get the item for $200 versus $400. The message states that the “suspension system is off.” I have to push the reset button to get rid of it. I thought that the person that installed it would be able to call the toll-free and be instructed on how to turn the light off. Other than that, I am very satisfied and would recommend strutmasters to anybody.

Strutmasters was my best find ever. I own a 2003 Lincoln Navigator, Great SUV, But the air ride is a problem we bought this suv in 2005 still had warranty left and we bought a extended warranty till 75000 miles in that time the air compressor went out 3 times, 2 times under warranty, this last time at 95000 ford wanted 499.00 plus labor for something that last about 18 months, then i found strutmaster there site and there sales staff, are very helpful even when i was installing them, i call my Sales man Anglo with one very simple problem, i felt stupid but Anglo was very helpful and walk me right through it, This SUV is my wife’s dream car She is so happy with ride and no more waiting for the air ride to air up, are those terrible rides home with no air. we are planing on keeping for many many years. I took Anglo advise and put them on e-bay and sold them used, also advised many buyers to you site, that could not buy them from me used, Thank You Again Strutmaster. a customer forever.

I am very satisfied. Now that the conversion is in place, I realize how many problems the faulty air suspension system was causing to the whole vehicle. Thanks, Tom

Name: | Location: Katy, TX United States | SKU: FX24F

I am pleased with my new suspension system. I wish I knew about it earlier, I would have saved lots of money, time and frustration. The only complaint I have is that the suspension light continues to come on. We need a solution!

Name: | Location: latta, SC United States | SKU: FX24F

Best money I spent in a long time…No more air bag problems….Thanks Strutmasters….

Name: | Location: Willaimstown, NJ, United States | SKU: FX24F

Thanks to you for your product and staff. I just completed installing the 4 coil-over strut conversions on my 2003 Navigator. Purchase was a breeze with you friendly folks on the other end. Installation was as easy as advertised and the ride is very comfortable. No more worrying about leaky airbags, long-running compressor, etc. Thanks again for developing such a good product and making it easy for a shade-tree guy like me to install.

Name: | Location: Edwards, MO | SKU: FX24F

“Everything went great! It was one of the easier upgrades I have done on a car. The parts fit perfect without any modifications. My next door neighbor assisted me and he was amazed how easy the upgrade went. It took about 45 minutes a strut which includes taking the wheels off and on. Very pleased with the ride and the look of the navigator now that it is not sitting flat on the frame.

Thanks for professionalism of your company, the excellent product and the followup.

“This was one of the best choices I ever made to change the air suspension on my navigator,no more problems,save money,great product,very helpful rep.
thanks again for a great product Gord”

Name: | Location: Scottsdale, AZ United States | SKU: FX24F

“I recieved the subject order on the day you said that I would, so that went well. I had the struts installed on my 2006 Lincoln Navigator and things seem to be well with that too. We think that the ride is stiffer than with the air suspension system but is acceptable.

I hope that the replacement system holds up better than the factory system that is defective by design and operation.

You asked for before and after pictures so I will send them under a separate e-mail.

I purchased the Strutmasters conversion package for my 2003 navigator and experience a wonderful ride. Prior to the conversion I was in complete dismay, the front airbags slowly leaked, I was riding low, leaning, bumpy, and probably dangerous. Now I am experiencing a wonderful, wonderful ride. At this point I have only praise for the quality of items I received with Strutmasters. Wonderful, wonderful product, wonderful customer service, everybody was wonderful with me.

Name: | Location: Monroe, MI | SKU: FX24F

Thanks they worked out great

Name: | Location: SAN CLEMENTE, CA United States | SKU: FX24F

I installed the kit in less than three hours, and it was pretty easy to say the least. Everything lined up nice without any modifications or the use of a hammer.

Name: | Location: South Bend, IN United States | SKU: FX24F

I wanted to let you know I was TOTALLY SATISFIED with my Strutmasters experience. I had even ordered the springs/shocks for the wrong model vehicle and didn’t realize this until I received that package. I talked with Donielle and she handled everything. You also returned the original purchase price to my acct in a timely manner. Although it was a pain changing these items (because of shock top bolt placement) if I needed to replace this on another vehicle, I would use you guys in a minute.

Name: | Location: Los Angeles, CA United States | SKU: FX24F

We had installed the Navigator Conversion Kit with no problem and returned the car back to our customer yesterday.

Name: | Location: Corona, NY | SKU: FX24F

I’m satisfied they fit perfect. Thanks your product is the best.

Name: | Location: Miami, FL | SKU: FX24F

My overall experience from conversations on the phone with the techs, to the instructions provided were great and I would not change anything.

Name: | Location: Odessa, TX United States | SKU: FX24F

I purchased the coil over kit for my wife’s 2004 navigator. Strutmasters was easy to deal with and I received my order in only 4 days. It only took 3 hours to install the new struts and the ride and drive is as good, if not better than the factory air ride.

Name: | Location: Rochester, NY United States | SKU: FX24F

Everything worked out great, those things went in very easily, I did it right in my driveway. I would definitely recommend these to somebody else, thanks

Name: | Location: South Portland, ME | SKU: FX24F

Thank you for having these replacement parts. I wish I had known about these a year ago, before I spent $1600 on new air bags and a compressor just on the front. I am not mechanically inclined but found these struts easy to install. Thank you again.

Name: | Location: | SKU: FX24F

I could not be happier with the conversion kit I purchased for my expedition. I love the SUV but of course the only drawback was the factory air ride system. Purchasing and installing your product was cheaper than having Ford fix even one component of the system. The ride is just as good and my truck handles great! My local mechanic even wants to start selling your product!
