alright, well i pulled the tensioning pulley and belt off, and found out that its not the tensioning pulley making noise, its the comressor, or the ac clutch. its the bearing in that cause i can turn it by hand and get the same sound, to a lesser degree. oh joy. looks like ill be rolling with no ac for the rest of the summer. ha ha thinking im just gonna yank the belt and call it good for now, cause i did start it while i had the belt off and sound completely went away with no belt on there. oh and btw...put some WD on both with no effect at all. well if anyone knows anything that is significant about it just let me know. (like a decent website for rebuilt ones, etc...) thanks again for the answers.
