The pulley on the ps pump is wobbling? Not good. Go ahead and take the serpentine belt off so you can better asses the pulley's condition as well as all of the other pulleys, etc. The ps pump pulley may be just loose, but you should check for wobbling and looseness at all of them. Unfortunately, if the pulley has wobbled too much, it and the ps pump shaft may be too sloppy and worn to mate tightly. I'd hope and expect your pulley is just loose and not damaged. Offhand I don't recall if it is held on by an allen head bolt, could be either metric or english. Actually the belt on the pulley is a good way to keep it from turning. If it has holes in it, you can keep it from turning with a long screwdriver. If the pulley only is damaged, the junk yard or dealer would be where I'd expect to find one, but you could ask the parts store. Usually, you take the pulley off to take the pump out and then just exchange your old one for a new one without a pulley on it. Even if you wanted to get the pulley and pump from a junk yard, you will have to seperate the two, but you will most likely get a good deal on them as you will most likely have to pull it yourself. Hopefully, you will be able to borrow the pulley puller from a parts store.
