2005 front end noise: woomp woomp?

[westtexas]

This is driving me crazy. This noise has been going on for many, many months now, but has been "livable".

2005 Expy 2WD Eddie Baur, 5.4L.

I get a noise which seems to be from the front end, hard to describe except to say it sounds like a tire/rim is out of balance. You can hear it from about 15-20mph up through 60ish, but it is most noticeable around 40-50mph. Kind of a (don't laugh) "woomp woomp woomp" sound from the front, increases in frequency with speed.

I've swapped out front tires / rims, and have replaced the front brake rotors and pads (just went with Powerslots and Hawk carbon fiber like on my F250.) Doesn't seem to have changed at all.

I'm at a loss. The front wheel bearings seem to be fine, at least as far as I can tell, no noticeable noise when turning them by hand.

Any suggestions would be welcome, I'm at a loss. U-joint? Front bearings? Other? Just don't know.

On a side note, I had the "grinding" sound while turning left or right from a stop, was the limited slip clutch pack about a year ago, and that is now going out again. Sheesh.

Thanks a million in advance,
TX

same

i am having the same issue with my 2003 expedition, changed the driver side hub assembly and brakes, still getting the same noise from the driver front. my next thought was to change the cv axles. when 4x4 is engaged and i turn hard left the noise is worse. any advice would be greatly appreciated.
