Did you hit it with a stethoscope to sort out which one it is?
Nah I'm at work, I heard it when I parked. Took the vid to listen to later when I get home. I'm thinking it's the idler to the left of the alternator. I replaced that when I first got the truck.

What do you guys think? I don't have access to sound at work.

I hope so. Hope it aint the alternator or PS pump.
From the vid it definitely sounds like the Idler pulley. But even if it turns out to be the alternator that's an easy fix, too, just more spendy than the idler pulley. Alternators on these rigs is pretty much a 30 minute job if you relax and take your time.

Need to see if I saved my lifetime warranty receipt for that for my cheap ass. :)
