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!”

“Good morning,

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.

“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 used the conversion kit for my Ford 2003 Expedition, and it was easy and only took me and a buddy about 2.5 hours to do all four wheels. The ride is as good as the air suspension, and i dont have to worry about any more broken bags. the cost of doing all four wheels is less than doing 2 of the air bags, and I had already replced the compressor once. The height of the vehicle is approx1-2 inches higher than the air suspension, but i like the higher look. Thanks strutmaster- well worth the money.

Good product. Easy install. Took about 5 hours. I would recommend this product to eliminate the air ride.

“Just wanted to let you know car is riding great. Wanted to let you know I had a company here named, Lincoln Land, put them on for me. The head mechanic stated he was impressed with the Quality and Workmanship of your product. He had never used your products before, that says something to me. And let me tell you that is one busy place for Lincolns. Thanks again, you saved me close to $3,000 dollars.

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.

“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.

Customer service was great, thanks Brad and Evette for all your help…..i was very skeptical about purchasing this kit because of the different reviews good and bad. Well I purchased it for my 03 lincoln navigator with 24″ rims and I love it, I can’t tell the difference from the ride before the kit, one thing I will say is that I think the big tires made the kit look better , if your tires are smaller than 24″ it might look funny(which was one review I read)but not so sure. I’m glad I didn’t get the lift kit because it would have made my truck sit up too high and look weird

“So far so good ! Had Firestone install the set about 3 weeks ago. This weekend we’ll take our 3rd 600 mile road trip through the hills of Arkansas without worrying about the suspension.

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!!!!!

(Product Code: -XN44-2-4) As always Strutmasters gets me the right parts and fast shipping even to me in Hawaii.Have only used Strutmasters for my company the last 8 years for all suspension kits.Jay is a super great and knowledgeable person.Kits even get better after time this one came with Eibach coils.Highly recommend Strutmasters to anyone looking for suspension components. Mahalo to the entire Strutmaster family for making quality kits at a great price and proper fit always.

I ordered the complete kit for my Lincoln Navigator. Havent installed it yet due to weather but the products are extremely heavy duty and high quality. The only recommendation I have for Strut Masters is possibly changing the color from red to black on the coil springs. Red stands out inside the fender well and on an all black vehicle, its slightly unsightly.

“I got the Strutmasters Conversion kit and I am Extremely Happy with the results. Its only been 3 days of having them on, but the anxiety of wondering when and how your vehicle is going to drop was unbearable and StrutMasters has relieved that anxiety.

I did a lot of research on the Air Suspension problems with my Navigator. Ford kept wanting me to come in for a $150.00 diagnosis, saying it would probably only be a $300 – $500 part replacement to preserve my wonderful air ride, and that I wouldn’t be happy with a conversion. No Way, No How.

Just Read on the internet, people spending $1000’s each year to get something replaced on their Air Suspension. Once it starts to go you will be forever troubleshooting the problem.

I only had the Air Suspension problem for 3 weeks, I could not let my family’s life’s be at risk any longer.

Do yourself a favor and get the Conversion kit, Not a Penny wasted.

Thanks SturtMasters.”

As the subject states however I was pleasantly surprised. The truck sits about 2″ higher which I think is normal. I believe it was riding too low to begin with do to all the issues I was having with the air ride. I am very happy with the handling and ride quality. I did the install myself and if you plan to do so make note: besides a good standard socket set including 15mm, 19mm, you will need a 30mm socket and wrench to get the coil bolt off. Also a good floor jack to raise this heavy truck and two heavy duty jack stands. A impact gun would be a big help for you as well to get the bolts off. I did the back two first then did the front two. The back went it super easy, the front I had to get the floor jack under the coil and jack it up just a tad to line up bolt hole but it was not a big deal otherwise. I am glad I took this route no more worrying about a bottomed out truck especially when I am up North somewhere towing my enclosed trailer with a bunch of ATV’s in the back.

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. markagarcia@msn.com.

Excellent quality & great handling. Would recommend to anyone as alternate to anyone considering repairing/replacing their air suspension. A+

My husband is unemployed and broke, he was a very happy man when he finish the job. Save us thousand of dollars and he is now worry free from air air suspension going bad. Thank you strutmaster

Yesterday UPS arrived around 10:00 with my new Navigator suspension. I have spent over $6,000 with the local Lincoln dealership in the past 5 years fixing the suspension issues. I delivered the car and the new Strutmasters system to my mechanic. At 4:00 he called me to say I no longer had a “Lowrider”. He charged me $226.00 to do the install and so problem solved PERMANENTLY for less than $1,000.00. Car rides better than ever and my wife is thrilled. THANK YOU STRUTMASTERS! Your postcard is one piece of “junkmail” I am glad I looked at.

“The left rear airbag on my 2003 Navigator went down at 90,000 miles. I read the stories on the forums and decided to abandon the stock air suspension. I am certain it was the correct decision. The kit was at my home in less than a week. I installed it in my driveway in about 2 hours. It was easier than doing a brake job. The ride is great! And I have piece of mind knowing I will never have to worry about it again.

“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.

“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! ”
