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 vehicleâs 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.

Real Customers, Real Reviews
Read reviews from people just like you looking for the perfect solution for their suspension needs.
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!”
Just wanted to say thank you thank you thank you for the struts for my 2004 expedition. My friend that put them on said it was simple n now I dont have to worry about leaky air bags. Its a little higher n I love it.
“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.
Just Installed a full set of replacements for my 03 Navigator. Very pleased!!!! Is it as smooth as the air ride, no. But it sure is a lot cheaper in the long run and not a bad ride at all! I have took Pictures from before, during and after. feel free to email me for em. [email protected]
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.
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!
“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! ”
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!
Good product. Easy install. Took about 5 hours. I would recommend this product to eliminate the air ride.
I know everyone is entitled to their own opinion but sometimes they your keep lies to themselves. The first review that talks about the ride is not great and these struts are not worth it is a complete lie. I just installed my struts on my 04 Lincoln Nav and I swear it is the best thing I have done to my SUV. The ride feels just like the air ride suspension and I put that on my life. I am so impressed with how my truck rides, it feels like I just bought the truck off the showroom floor. Was not hard at all, all you need are the right tools and a little muscle and you will have no problem getting it done. I would say if you can change oil you can change your struts, Strutmasters you truly are masters of strut and I salute you!!!!!
“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.
We received the conversion kit a few days ago. We had the work done the day they arrived, so I was unable to take pictures. Everything went well and we are surprised how quick and easy they are
to change out.
All Care Automotive”
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
My overall experience from conversations on the phone with the techs, to the instructions provided were great and I would not change anything.
It’s been 3 weeks since I had the kit installed and I’m very happy. I should have done this years and thousands of dollars ago. Thank you Strutmasters for a great product. I will be recommending you guys to all my friends that have air suspension problems.
Did the install in one easy day by myself in my garage. No air tools, only tool I had to go get was a large metric socket (30mm) I think. Way easier then the install I did on my Mark VIII!! And the ride seems about the same, just got back from a 1200 mile trip and it road fine, even through the WV turnpike at 75 mph. I’m currently looking for another Nav with air ride issues to buy cheap and do an install on. Love this car.
Best money I spent in a long time…No more air bag problems….Thanks Strutmasters….
The shop that I took the kit to were blown away with the ease of design and engineering. They had never heard of your company and said they would contact you to be a dealer. Here in Michigan we have some of the worst roads in the country. Thanks for a great product. My Expedition loves you guys.
“Just had my air suspension replaced with the “”2003-2006 Lincoln Navigator 4-Wheel Air Suspension Conversion Kit (2WD & 4WD)”” I am so relieved, the ride is great, and the quality of the struts were great (according to my mechanic and from what I saw)! Delivery took about a week and the tech service, and Dustin & Vito were more that helpful!
Living in the Denver area, every time the temp would drop below 20 degrees so would the front end … when it did it while I was on the interstate at 65 mph it got my attention … started to get the “”bring it back in if it does it again”” story from the dealership … what a pain — Thanks Dustin, I am very happy with my new “”ride”” :0)
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.
“Well, I didn’t want to do this at first, as sooo many people that did the air ride conversion have been unhappy, but none of them have used strutmasters kit… if they have, they would say it is nearly the same as the air ride… I wish I would have just done this from the start instead of wasting the money I did on the air ride system, which never did get fixed correctly.
I would say it’s about 85% the same – but the trade off is that I will never have to worry about waking up in the morning, going out to my truck, and have it sitting low, and not pumping up…
All in All, it was a wise choice – I didn’t like that they charged me a $5 handling fee and didn’t tell me about this, (thus the 4 out of 5 stars) but as I say, you can’t beat these… they are heavier than I expected in the boxes, etc… so that was a nice surprise! The springs are beefy, and I love the red power coated paint job!
“Many thanks to you guys at STRUTMASTERS !!!! My wife’s 2003 Lincoln Navigator was diagnosed with Air Bag Cancer. I checked everywhere for a solution because my wife LOVES her car. Every solution form Lincoln said $$$$ which we could not afford. I began to put my fingers to the Cyber Net Keyboard for solutions and found your website! The video made it look a little bit TOO easy (if you can do brakes . . .. I checked the BBB for their complaint issues and found them to be in good standings. I was a little hesitant to order over the internet, so I used a debit card and WHOLLA! I ordered it Sunday and it came Wed afternoon! I had all the tools EXCEPT the one to remove the large bolts from the bottom Strut, so I enlisted the aide of my Mechanic Mr. Chase of Bernard’s Auto of Bklyn, NY who installed all 4 for a minimal price. Everything (including the Struts) came to UNDER $1000!!!! So if your tired of chasing the Dealership Rainbow for a solution, try STRUTMASTERS for a cure to Air Bag Cancer and give your ride a new LIFT on life.

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
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
Thank you Strutmasters! I have had issues with my Air Suspension system for 3 years now and $3,000 dollars later the mechanics still cannot pin point the issue. I removed the air struts and replaced them with your conversion kit. The instructions and videos made it easy. I am not a mechanic, but your videos made it real easy. thank you so much. The Nav rides great now and no more worries about the suspension. Awesome product. You have a customer for life.
“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”
I kick myself for not finding you guys a few years ago when I started battling the air ride on my wife’s urban assault vehicle. Long story short……after replacing a compressor and two level ride sensors we still were in lowrider mode! Of course temperature played a role (anytime it dropped below 40 degrees F). I bought your XN-44 and installed them over the weekend. (the comment about “if you can do a brake job you can install these units”…..is accurate! For a self proclaimed shade tree mechanic it took me 3 hours to complete with no lift. The wife thanks me everyday for not having to battle the rough ride. Well done Strutmasters……well done indeed!
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
