2000 Exp. Eddie Bauer - "grinding"
I have scoured the posts and could not find one similar to this. 2000 Expedition - Eddie Bauer: 39,000 (not a mistype) 4AWD has developed a "grinding" noise whenever I want to merge onto a highway. A casual start from a stop is no problem, but when acceleration is needed, a grinding noise apprears and the floorboards on the driver's side "shake"; I can feel vibration beneath me feet. One dealer says that it might be the transfer case, another states that it could be the differ.; guesswork? (each was from a Ford Dealer). Noise appears whether vehicle is warm or cold. Would truly appreciate any guidance.

Possible for either or, but have you checked the crossmember bolts for tightness? Check the driveshaft and look for any scoring from rubbing against something. If the bolts aren't secure on the crossmember or any other associated piece, the motor will torque the driveline and if its a moving piece it will grind against whatever it finds.
This will have to be a visual assessment.

I have a 99 XLT with a somewhat similar problem with the A4WD. After I drive mine for a few miles is when I notice it. When making a locked wheel left turn into a parking spot. It makes a terrible clunking noise and it seems to be coming from underneath my feet. If I make a locked wheel right turn there is no sound at all. If I just start it and do it it doesen;t do it either, only after drivng it for a few miles. I think it might be a GEM problem. Any suggestions?

May I suggest replacing the transfer case fluid.
I had a situation at about 32,000 miles in which I could feel a slight vibration that seemed to come from the back of the vehicle while making fairly tight low speed (=/- 5MPH) turns.
Even though my '99 Expy doesn't have a limited slip diff, the service dept. at the dealer pulled the rear diff cover off to check everything out. Everything was fine. Now the theory was that the front diff or a front c/v joint was somehow causing the issue. Dealer practically dissassembles the front end of the vehicle, cures a minor front diff leak, and bolts it back up. No change.
Finally, I theorized that somehow the transfer case was partially in 4WD, and suggested that possibility. Raised a few eyebrows at the service desk, but the techs re-reviewed the problem and concentrated on the T-case. Problem found. Apparently, a small quantity of water had contaminated the transfer case fluid and caused some misbehavior. I've never driven the vehicle in water deeper than that found at the car wash, but once they drained and filled the transfer case twice (with a little driving in between), the problem disappeared. The last 46,000 miles have been uneventful from a transfer case perspective.

High_Horse and PaulC:
Finally had to take it another dealer today and she's currently still with them. I mentioned to them about the transfer case fluid and they sorta looked at me oddly... will report to you all when she returns!
Again, I thank you all for the input!

Grinding...
Just wanted to thank all of you for your input! I was out of town and could not get to the internet (go figure)...
Anyway, it turned out that in the time that the original owners had the truck, they never had the transfer or transmission serviced. Apparently they had been under the impression that since the 4X4 was never used that they didn't need to service the transer case.
Long story short; I had it serviced and it appears to have wiped out the "grinding"...
Again, I thank you all for the valued input!!!

Its not so much its bad, its to be sure its up to operating levels. Any tranny service should check your fluids for free and make recommendations from there.
As for the fuse, I have a 2x4, but your owners manual should show that.

Just so you know, I had the exact same symptoms as you, and it went away COMPLETELY with a tranny flush.
Ford recommends the tranny flush every 30k I think, and mine, I am sure, was way overdue. It is cheap insurance, even if you didn't have a problem already. Give that a shot, and let us know. BTW, mine is a 2000 A4wd, 100k miles.
