I believe my power steering pump is going to shit. It rattles and squeels and has a ton of play in the bearing. Figure the bearing is shot. I've scoured the junk yards looking for a replacement but havent had any luck. Is there anywhere that sells cheap used pumps? Is there an upgrade or alternate pump that I can use? I have everything at my disposal to machine new brackets and such. I'm not running huge tires or anything, i just want something that works. I was reading some sammy threads about using a celica pump. Could I possibly use a toyta pickup pump? What others are out there I can use to get this working again?

Thanks for the help guys.
