My alternator installer checked it out, said they installed the pulley wrong. There was something that was supposed to be tightened down that wasn't. The metal around the pulley sheared off maybe a quarter inch or so, pouring out the oil i saw and causing the wobble, or the wobble caused the shear, and the belt came off.
