Gotta agree with Rocky. 70-80 ftlbs isnt going to pull the ball out of the socket. My bet is you have the wrong castle nut. If you stretched it that much it would likely have broken or at least be deformed enough that you could see it. Compare the stud length and castle nut to the others you installed.
