I just noticed a similar thing in my truck. Mine is when above 60 mph. but only when I let off the throttle, and just for a few seconds.

I wasn't going to reply because after over a month I would think you figured out the problems but Oakleyguy if you sure it's on the front I would think it would be bearing or tire.ab2625 I would think u joint or play in the rear axle,hopefully u joint.Good luck and if you figured it out already please post your findings for other that may have the same ploblems.

start easy, rotate tires and see if it moves. Anywhere particular in the front end? I hate chasing these gremlins on 4WD's. Most likely is driveshaft u-joint. rears usually wear faster than rears as they are under stress more often. Front axle u-joints also wear and could be your problem.

While your driving and if you turn slightly one way or the other does it go away? Humming noise general at those speeds your saying will be a front wheel bearing. If its tires it will be there all the time even at 25 MPH you will hear the tires humming. What kind of tires are you running?

Is the humming noise associated with any sort of Vibration?

I had a similar issue with my X, would start humming around 55-65 and go away. I had this issue for over a year. Had bad ball joints, which caused the tires to wear out of round, more humming.... Replaced ball joints, tires, problem still exists but fixed bad tire wear. Ended up being a out of balance drive shaft.

I get the humming at 65mph too

I have the same hum. '00 F350 7.3L automatic.

Key to figuring out this problem for me is that as soon as I drop it into neutral and the rpms go down, the hum ceases - even though the truck is still going down the road at 65 mph.

Did anyone here solve this?
