Okay so about a month ago, I started to get a whining sound from my serpentine belt. Being lazy, I kept putting off looking at the pulleys, and now, well yeah... This morning I started her up and the whine had turned into a much louder groaning noise, with a vibration I could feel in my shifter. I could smell the rubber of the belt burning. So my question is, what is the easiest way for me to figure out which pulley is the problem, and is there the possibility that it is the harmonic balancer on the crank pulley? Does the qr even have a harmonic balancer. Any advice/help would be appreciated. Thanks.
