Need new steering gear box

Well, don't do what I did. About 15 years ago, I bought an A-1 Cardone rebuilt PS box from Advance Auto. My steering was a bit sloppy, so I thought that would fix it. I noticed virtually no difference, and the box is a BIG pain to R&R with headers. I have since heard that many rebuilding companies like A-1 Cardone only replace what is really bad. Then they clean it up and put it back together with new gaskets. I don't know if that is true or not, but the money I spent was a waste.
