This 98 expedition only has 92,000 miles. A month or so ago, I found the rear end sitting down on the axle. I started it up and suspension pump came on and leveled the vehicle. Drove it for a while and came home and parked in garage. I jacked it up to look at the condition of the air bags and they looked good. This vehicle has always been parked in the garage and we don't have a lot of freezing weather, so salt is not used on the roads.

Any way, a week went by and the suspension never went down. Took it out shopping and heard the pump come on a few times. Shopped for about an hour and came out to find suspension all the way down. I suspect something gone wrong in the control system. Have researched it a lot on line and found that the leveling sensors hardly ever go out on this model. I found mentions of compressor relay failures, but the pump always comes on, so I kind of doubt that.

I spent 35 years in the auto sales and service business, and know that most vehicles fail in the same ways. Hopefully someone reading this can give me an idea on what to look for. I have the shop manuals, but they require a star tester to pull codes out of the module.

I will probably end up replacing the air bags with standard springs, but want to do that as a last resort.

My was telling me that the vehicle felt different. So I drove it for a day or two and definitely noticed that something wasn't right. The vehicle was very "bouncy." The air ride pump would come on three times to lift the rear end and then gave up. I brought a bottle of soap bubbles to see if one the air springs has a leak. Sure enough, it did. Due to the mileage it obviously didn't have a warrantly of any kind. After doing some research on air suspension repair I felt that it wasn't worth replacing air springs valued at 400 dollars a piece. So I went to a junk yard and luckily found a newer Expedition with coil springs. I then had a mechanic install those springs and take down the air springs. I shut off the air suspension and turned off the "Check Suspension Light" on the dash. Ford needs to reinforce those damn air springs.

i have had so many problems with this truck from the first day i bought it the back end dropped about 3 times all ready the first time they reset the relay switch the second time i put a brand new relay switch in it then it still drooped down again and now i don't know what to do someone please help they said to take it to the ford dealer but i was readind the other comments and im afraid to they just going to rack u up for a big bill also i was thinking to change over to regular shocks what do u's think ???? is it possible

My Expedition is used, but in good shape. A few months ago, I came out of a store to see the back-end of my truck slammed to the frame. I drove it home in its condition, in what was the bumpiest and most dangerous ride of my life. I took it to a ford dealership, who after gouging me with initial diagnostic fees told me it was some fuse. I paid over $300, and that was last month. A few days ago the back dropped out again. I took it to a local mechanic who said he believed it was a short in the wiring of the air pump, as his voltage levels were unusually fluctuating when he applied power to it. After starting the truck back up, it somehow raised it up. Regardless I took it to a Ford dealership. They called me today to tell me there was NOTHING they can do. They said it was in working condition, so there was nothing to diagnose, and that I would have to just wait until it crapped out on me again, and then bring it in. Well guess what?! As soon as I got home the piece of sh*t dropped again. I tried taking it back, but they conveniently were closed. I will take it back tomorrow, and if these people feed me the same line of bullshit, while charging me money for useless "labor" I'm going to start kicking ass.

As we all have gripes about our new/used cars, it is really frustrating when the vehicle has to go in to be repaired. Whether it is under warranty or not. I bought my 1998 Expedition new in January of 98. It has been in and out of the service department for recalls, few minor problems and the air suspension. Other than the few minor problems, the air suspension was the main reason why it had to go in for repair. Ford stood behind their 5 years of warranty that i paid for and repaired my car. BUT NOW that the warranty is up i still have an on-going problem with my suspension. Ford does not have a policy for pre-exsisting problems which is what I had 1 year from buying this car. . I spent $700.00 of my money to replace a broken torsion bar that was broke in doing that they screwed up my air suspesion on my car . First the passenger front side of the car was sagging 9 days after the torsion bar was put on (which was that side of the car!) Then they charged me another $99.00 to ajust the leveling of the car which was under my new warranty of 12 months/12000 miles. THEN i go to pick my car up at the dealership and the rear-end of the car was sagging so I left it there so they could fix there wrong doing. THEN while waiting for the car the mechanic tells me "he really doesn't know whats wrong with it. THEN they tell me that "I'm just going to have to be happy with the way the car is ". The paperwork I got was just for the adjustment on the front-end. NOW they wouldn't give me any paperwork for the work they've done since the "SAGGING REAR-END"which took the remainder of the day. I think FORD should really take a look at situations where when their employees treat loyal customers like crap thinking that we dont know any better. Well my car is going back in for the "SAGGING REAR-END" needless to say they'll try to get more money from me or try to sell me a new car, HA!
