I can't empathize what Scotty is saying enough. I had to replace my PS pump as well, but by the time I did it was too late and now I have to get a new rack and pinion put in. The PS pump is easy to to do if you have your own car lift. If it, it's cheap to get done at a shop. A lot better than having to buy a new rack and pinon ( can cost as much as $250 ), and paying to get it in ( Another $300-$350 right there ).
