I have a 1500 5.9 V8 supercab. In the front by the passenger side is

making a noise only when I'm driving it sounds like a tire rubbing

noise but it's not the tire it doesn't do it when I'm at a stop. Does

anybody have an idea what it might be?

it could be a number of things to be honest. i have had noises like that in my truck, and it was on both sides. not at the same time. the first time it was a seized u-joint. then the second time it was the forward dif low on fluid..it made this horrible rubbing sound. but it was intermittent. so it wasn't happening all of the time. every few minutes. but you couldn't tell when it was going to happen. it could be a wheel hub, or anything.
hope you find this problem with no trouble.
take care.

yeah i know the forward diff isnt on any side of the truck its in the middle.. just sounded like it was coming from the drivers side. so just had to clear that part up.. hah hah hah
