My wife has a 2003 mountaineer and she would always say that every once in a while she would hear a very fast and high pitched "whoop" noise. I though she was crazy but i was driving it the other day and I heard it. It is coming from inside the cad maybe in back seat. It is not the radio because it was off, any ideas?

I'm getting a whooping noise that sounds like it's coming from the right rear side. Noise is intermittent, and most closely resembles the start-up of a police car siren. Noise lasts about a second, although on rare occasion it will drag on for a little longer than that, and sometimes it sounds more like a groan.
It happens regardless of whether I'm driving, stopped at a light, or in park.
I can't forcibly replicate the noise or predict when it will happen. If there were some kind of a pneumatic load leveling system in the rear end, I'd suspect that since the noise could almost pass as air leaking out. It's definitely coming from the back end of the car.
It doesn't sound like the same pitch as the back-up sensors. I also considered possible venting from the gas cap, but the noise happens regardless of tank level, temp, humidity, altitude, etc. Only other thing back there is the subwoofer, but it makes the noise regardless of whether the stereo is on or off.
I've had it to two different dealers, and neither could find anything in the Ford database and couldn't get the noise to replicate itself. They want to think it's everything BUT what I've described. Wind noise (replaced weatherstripping on a FRONT door), even though I've told them that it's coming from the rear end and I don't have to be moving for it to make the noise, aftermarket stereo (but it was doing it before I installed the aftermarket stereo), and they keep referring to it as a "pop" when I keep telling them it's a "whoop." I even printed out posts from several other owners have the same problem and gave them to the service rep to show that I'm not the only one having this problem. Yet there's apparently nothing in the [COLOR=green ! important][COLOR=green ! important]Ford[/color][/color] database of anyone else having this problem.
If you have had this same problem and got it fixed, please let me know what your dealer did to solve it. It's not a something I can voluntarily replicate or predict when it will occur, so troubleshooting is tough. I'm thinking of riding in the 3rd row whenever my wife and I are in the car together so that if it makes the noise, I can pinpoint where it's coming from. Otherwise, I'm at a loss, and my dealer is too (or he doesn't want to deal with it.)
Trying to see if the noise happens when rear AC is on. So far, only hearing it when it is off so this person may be on to something. Anybody else?
there is a noise that I think may be yours ---see if this sounds right -- if you have rear a/c , there is a valve in that system -- this valve may make noise when the front a/c is on low blower and the rear a/c is off , it makes the noise more in this mode-- it will happen at any speed and make this hoot sound and you can not tell if its from the front or the rear --- to disprove my theory ,, try to see if the noise is there with or with out the a/c on --- if by turning the a/c off and driving and the [COLOR=green! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif][COLOR=green! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]truck[/font][/font][/color][/color] and it never makes the noise ,, then I am on to something --- if it still makes the noise with the a/c off ,, well then I was wrong -----take your time and get back to be me ---noise problem are hard to diag , especially on the web ,,
I am experiencing a similar problem. I have a 2004 explorer, 4.6 v8, 4 dr 2wd. My wife has heard it many times, me only once. I have read there is a problem with the rear bearings in the form of a TSB. Does anyone have info on this? Is it serious enough to have to replace the bearings? Or can I continue to drive it as is. I have suspected the AC but my wife said she turned it off and the noise continued. HELP! This is driving me nuts.
I have been having this exact same hooting noise with my 2005 Eddie Bauer that has 45,000 miles. The noise lasts only a second and is coming from the rear of the vehicle. The noise does get louder with acceleration. I took it to the dealership twice but they were unable to reproduce the sound and because I am a women and they haven't heard the sound, they look at me like I am crazy. Any assistance would be greatly appreciated. Thanks!
I have the same thing going with my 2007 4.6 explorer. sounds like a cop siren. also it makes a noise like farting after the truck is stopped, like air escaping from the fuel tank maybe. other than that we love the truck.
my 2007 explorer does the same thing under the same apparent conditions. I just tell peolple its haunted but the service guys are scratching their heads
