I'm going to try to eliminate everything else first. The surprise thing is these pulleys have only about 1500 miles on them.
Mine were less than a year old as well. But mine are stock pulleys. No fancy dual bearings or anything like that.

. I had a couple of my buddies listen to it and they all thought it was a pulley.
