#76 of 88 noise accelerating or decelerating
Nov 06, 2011 (12:36 pm)
Our 2003 Ford Expedition (Eddie Bauer ed) 2WD with 105,000 miles just began making a grinding noise that sounds like wheels or front end. The noise got worse after towing a light trailer on a 4 hour trip...seems to be more profound on accelerating and more so on decelerating but is unnoticable on idle in park and less noticable at constant high speeds (60 or 70). Had the brakes in front replaced a few months ago and just one week past the oil change. After reading other messages, I am uncertain whether this is a bearing issue or transmission or ?

I am having the same problem and i haven't towed anything.
I would be very interested in the answers you receive. Could you send them to me.
I owe a 04 expedition.

Probably the differential. Had my 03 in for a replacement 175K miles. $2K dealership to rebuild ( replace gears/bearings) $1200 independent shop but opted for one from a junker $800 parts and labor. Lots of issues with the Expeditions with the independent rear suspension diffs. Honestly though, I drove ours with a whine for about 60K miles before getting it replaced.

Turns out, it was more than one thing...the wheel bearings were in fact bad...replaced for around $350...THEN at the same time, a spark plug blew completely out and took out the small coil attached to it (5.4L Triton V8) as well as the line to the washer fluid...the plug issue happened suddenly as I was pondering the scraping sound and was a load pop followed by loud sputtering as the engine limped on without that cylinder. After some searching, I learned that over 30,000 cases of this have happened and even law suits were filed for them...mostly to the benefit of the lawyers :/ Ford is not recalling though even though this seemingly is a defect in all models starting around 1997 through 2007!!! I won't ever but another Ford vehicle.

follow the exhaust pipe. check those heat shields that separate body from pipe, muffler or cats. if those are loose, it will sound like the truck is falling apart.

check wheel bearings.

I'm guessing since that post was almost 5 years ago it is probably all set.

i have hade a persistant "WHOP,WHOP,WHOP" noise whenever i am driving my 2001 expedition. i have had the rear-end replaced and it is still there, just not as pronounced as before. they told me it may be the e-brake or a bent backing plate. the rear end was used with 60000 miles. any chance i got another bad rear end?

My 1998 Eddie Bauer Expedition is making a sound similar to what you describe. It is intermittent and seems to come and go and I haven't been towing a trailer with it. Differential sounds like a good possibility, but it has low miles. A wheel bearing would be constant. This "grinding" noise is most noticable at very low speed. any other experiences or ideas out there?

I am re-posting this now since it was 2010 when I first solved my problem and posted it here. Following is the original post:

I had the rattling sound from the wheel area too. I took it in to the dealer and they rebuilt part of the transmission which did not solve the problem. The service manager took an interest in the problem and figured it out without lifting the hood. Seems that there is a vacuum valve that controls the 4WD hubs and when they get old they start to leak and the hubs are trying to engage at high speed which causes all the noise. I've got a 2005 Expo with about 50M miles on it. Until now I had never had a problem with it. Once they put the new valve in the noise went away and hasn't come back in a month.
PS. The truck now has 90,000 miles on it and the rattle has never come back.
