Front end noise, HELP!!

Hello all, i'm new here and I need some help please...

I have a 2002 F-250 7.3. I was driving home from work on Tuesday (highway), I heard an intermittent noise coming from the front end, sounded like a rubbing/grinding noise. Yesterday on my way to wok, same thing, on and off. Yesterday on my way home the noise was constant, didn't go away. The noise comes at about 45mph and stays until i'm back under about 45mph, so mainly just on the highway. I put the truck in neutral and let off the pedal and the noise is still there which tells me it isn't engine related.

Yesterday after work I jacked up the front end, spun the tires, no noise. No play in the tires top/bottom or side/side. Took the tires off and what I did notice is the right axle u-joint is shot. I am hearing the noise in 2wd so I don't know if its the u-joint that's making the noise. Could it be a bad wheel hub bearing? Is it the u-joint? Maybe needle bearing?? Before I go ordering parts, I wanted some input.

Thanks, Mike

Needle bearing and maybe the large seal.. Pull it apart and see whats up while you change the ujoint with a spicer life joint..Non greasable best available joint.
