I have an 06 f250 that is making a growling noise that is speed sensitive and sounds like it might be coming from the front. I thought it was tire noise from my old worn out tires but with new tires it still maks noise, but tires have pretty rough tread. How can I tell if it could be a wheel bearing? It seems like the noise quiets down a little on right turns. It is kind of a growling humming noise that changes with speed. Any ideas are appreciated. Thank you.

 

It sounds like wheel bearings, jack a tire up in the air and spin it if you hear the noise there you go. Also grab it at the 9 & 3 o'clock position, push and pull see if you have play, you shouldn't, if it is the bearing don't let it go you'll end up paying more for spindle or hub.

 

jack it up and hold one of the coils on the spring or a leaf and spin the wheel if you feel the roughness its in the bearing and mostlikley the outer , its the load carrier. on a 4 wd carrier bearings also will make noise especialy at lower speed, 10-25 mph

 

Thanks for the replies, Ill jack it up and try that when it dries up outside.
