Thrumming sound.
Stock 2005 Excursion Eddie Bauer 6.0....
I'm in Michigan halfway through my yearly trip around the country and my truck just started... Sometimes... Making a deep thrumming sound and vibration when accelerating and when I get off the throttle fast.
Intermittent.
Weird.
Any ideas?

Are you feeling it in the seat of your pants? Steering wheel? Feet?
Are you towing a camper? If you are and you have high mileage on the EX, you might want to find a shop that will put it up on a lift and check your rear pinion bearing. If that checks out alright have them move to the rear hub bearings. It really sounds like you have a loose pinon bearing. It is also possible the carrier bearings need to be replaced. I had a similar issue. I ended up rebuilding the rear end.
