just worked on it some today finally  
yes a two piece with a rubber ring it looks like. looks like the crank pull is the problem. it has a very slight wobble to it, causing the belt to deflect/flutter as it travels towards the power steering pulley. i guess i’ll start with replacing it and see what happens.
