My solutions was that the Pulley was loose, even if you tightened the nut, it still wobbled.  You shake the pulley with your hand and it wobbles in and out (side to side, the direction of the spin is okay).

I took a large thick washer and put it between the nut and the pulley.  It tightened up, and much of the noise went away.
