I have replaced all 4 pulleys, the two tensioner and the two idler pulleys at about 40$ each and it still squeked like yours is doing upon acceleration. I then changed the alternator at 140$ and the damn thing still has the squek. So the only thing left is the power steering pump bearing and the waterpump bearing but since the squek stays the same when turning im guessing its the water pump bearing so thats my last thing to change.

You guys sure it's not the ac pulleys? I have a new main tensioner so that's not the problem. I'm having the same problem so i took off the main serpentine belt and the bottom ac belt, spun the ac idler and ac tensioner pulley and they spun for way too long. So i'll be replacing those soon and I'm hoping thats the source. Was 25 bucks each pulley at Orielly, just waiting for them to ship to the store.
