steering problems
 

I have a 96 eclb 4wd with a ttb and I am having a hell of a time with this truck.

I replaced my steering box and well the pitman arm was a PITA obviously but my problem is with the ball stud that goes into the pitman arm spins when I try to tighten it. I've tried putting pressure on it and nothing just free spins. Am I able to just replace that stud on the drag link or do I have to replace the entire thing?
