I'd never seen a plastic power steering pulley separate from the steel hub, and was mildly impressed at it's cheesiness!

I'd prefer to smoke the belt if the pump locks up since belts are in stock more often than pulleys (I think this was an intermittent sticking check valve in the pump, not sure, but I replaced the pump/pulley with a spare I had stashed), so I'll order the all-steel Dorman replacement pulley for the next one I do.
