Doug,
I have recently been working on my steering rack.
You are talking about the passenger side of the car right? the opposite end or the rack to where pinion locates. It sounds to me like you need a bronze bush. All the vendors sell them. The original bush was made from some kind of nylon or plastic, and only lasts a few thousand miles.
After studying the rack and talking to a bespoke rack manufacturer, I decided there is nothing fundamentally wrong with the design, or the quality of the steel used for the rack and pinion. The bush is the main issue.
I had a bush made locally from phosphor bronze that is about twice as wide as the ones available from the vendors. I am hoping it will last twice as long.
Mike Drew wrote an excellent story on rebuilding steering racks. I think you will find this story on the Pantera place website.
I recommend molly grease for the rack, not oil.
