long-icon-xIs Your Suspension Failing? Ready to Order

How do I know if my 2003-2006 Ford Expedition 4WD Air Suspension is failing?

There are common signs that the air suspension is leaking or failed on your 2003-2006 Ford Expedition 4 Wheel. The most obvious is a sudden noticeable uneven height difference between different sides of the Expedition. You might notice sagging from the rear to the front end, or perhaps leaning from side to side. One side may look more inflated than the other. Maybe the entire vehicle seems to be squatting down too low to the ground. Overall, your Expedition ride height should be consistent and appropriate according to Ford standards; otherwise, you may be dealing with a bad suspension. Other signs include a suspension warning light or message in the instrument panel. Oftentimes, the air compressor ceases working, or maybe is running way too often (will be noisy). In all of these cases, a repair or replacement may be necessary before other major components on your Expedition wear out.

What kind of suspension does my 2003-2006 Ford Expedition 4WD have?

The 2003-2006 Ford Expedition is built with the following suspension components:

2003-2006 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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.

“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 installed conversion kit on 2004 Eddie Bauer Expedition with 100,000 miles. Front end conversion was good. After conversion rear end is low and has soft “springy” ride. I tried to get help from Strutmasters to fix the problem but they said the height was in the correct range even though the rear sat lower than the front. The more we drive the vehicle the softer the rear suspension gets. I’m now trying to decide how to fix the problem as the expedition now handles poorly on corners and when you hit any bumps. I would not recommend this product.

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

If you are having problems with your air ride you are going to regret not buying this kit! I have been fixing things here and there with my air ride until I bought this. Its will just Nickel and dime you! The parts are very high quality and were very easy to install. It took my dad and his friend 50 min each to replace them. I have been told by 3 mechanics that Strutmasters makes the best conversion kit they have seen! My truck rides better then it ever has. I feel much safer driving. The truck sits so nice, before the conversion the back sat abour 4 inches lower than the back. This is the way to go! Thank you Strutmasters for coming up with such a great product! Also excellent customer service. I placed my order over the phone on a Wednesday and had the kit by Friday!

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!

“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)

“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.
