Tires humming/drone noise??

I'm getting this humming noise that appears whenever I'm on the highway, and it goes away as soon as I give the steering wheel a pull to the left. Then it comes right back once steering straightens out again. It sounds like it's coming from the tires/wheel wells. Anyone have this issue before? I was thinking it might be an alignment issue but when I let go of my wheel on the highway I'm not noticing my truck drifting left or right away.or it could be the tires (Goodyear duratracs) with a good amount of tread left. Just recently had my warranty expire too

 

Sounds like your driver side wheel bearing is bad.

I second the wheel bearing motion. Mine did the same thing. Most noticeable between 35-55mph and when i turned left it would go away. Ended up being the front passenger side bearing

 

Lame. Yeah it shows up right around 50 mph
