Ok, squeaky noise came back. It seems to want to go away when it's warmed up so it's hard to get to look at unless I go out and start up the car just to check.

I did that today though, and it sounds like it is coming from the pulley just low left of the SC pulley. It's a smooth one. The guy at the shop I went to so he could check it out said he wasn't sure if it was a pulley or it was just the belt being too "glazed" and sliding around on it until it got warm. Does this sound like a possibility or is it still probably the bearings?

I did go by oreilly's to look at the new stuff. They looked it up and it was 200+ bucks for that pulley (I think it also had the mounting bracket on it), which is a LOT. So for you guys that have the knowledge, do I need to replace the whole pulley, or can I just get the bearings and put them in there?

And where would you recommend I order whatever part I need from to keep the cost down?
