Need a favor from those with SBM and power steering.

When I installed the serpentine conversion shown in my previous post I developed a squealing noise which turned out to be the water pump impeller rubbing the water pump housing. Evidently it was pressed on the shaft just a little to far and the extra tension of the serpentine belt on the pulley caused the impeller to make contact. New water pump and everything good again. Something else for you to consider.
