I cured the high pitched squeal when I changed the belt, but I still get a lot of noise under acceleration from the belt. Tried belt dressing and that made it worse. Anyone been through this and found out the pulley was the culprit? If so which one? I suspect the alternator pulley, but am not sure.

I checked and both are quite shiny....it's drivin' me nuts!!
