I’m replacing the: both inner, both outer and both threaded connectors. A whole new assembly. I have removed all of the old components except: the bolt attached to the arm that comes out of the steering box. The nut is off, that was easy, I can even thread it back on. Unfortunately, I have not been successful removing this 3-4 inch piece of metal (threaded on one end and a ball on the other end. I have tried , oil, the bolt remover in a spray can from Murray’s. The cylinder of metal is still in the hole. Any suggestions would be appreciated.
