I held off on posting this for a long long time, cause I was sure it was going to come right back. I am almost up to a year now with the whine gone. Might as well share this for others.
This is for the idler pulley that is on top, towards the front of the car. Take it off, turn it around, put it back on. Fixed. At least for me it has been. I was shocked when I first started it up. I thought for sure it would be back in a day, a week, a month, but it is still quiet.

From memory, looking at the serp belt from the passenger side, it will be on the top at far right. Closest one to the radiator. it is a ribbed pulley if that helps.
I was thinking about this earlier, I bet you could achieve the same results if you just loosened the center bolt and rotated the inner race 180 degrees. Would be worth a shot since you wouldnt have to remove the belt.

Doesn't that usually mean that the bearing is going bad?? I dunno if I'd risk it, just in case the bearing REALLY goes out and you throw a belt. Happened on my wife's Grand Am last year and ended up leaving her on the side of the road!

Yeah I would replace the whinning pulley. The bearing is on its way out and a thrown belt isnt any fun especially on the LS4s. Rotating the race wont save a failing bearing. I'd rather be safe than sorry and replace it. But knock on wood...all is quiet under the hood.

The inner race on mine was had such a minor imperfection that you couldnt even feel it rotating in your hand. Changing the loading on it was enough to make it go away.
Its not going to suddenly fail, without warning. Took me about 15 minutes. Long as you have a way to get the belt on and off.
