High pitch idle / whine sound

Does anyone else have this sound coming from their 6.2 during idle? It has a high pitched whine sound to it.

It seems to go away when reved and only present during low RPM speed. My truck only has 1,000 miles on it.

Nope. I have 6600 miles on mine. Sounds like a belt or an idler pulley bearing, maybe.

Great - I guess i'll bring it up during my first oil change. It doesn't do it all the time so hopefully they can diagnose it and it's nothing serious.

It only happens at idle RPM and doesn't seem to change sound with steering,
