Ok so I have a 1971 nova an replaced the whole front end suspension components (upper lower ball joints all bushings etc) and my lower ball joint castle nut keeps ripping out shearing the nut an ball joint stud clean off. It kept happening on the drivers side so I replaced the whole joint 3 times and finally used thread lock red to add support. I pulled out of my driveway and now my right ball joint but tore out leaving my nova with the control arm on the pavement. Any suggestions? Im out of ideas.
