When I was replacing the front struts on my Marauder, I loosened the two nuts on the passenger side sway bar bracket. One of the nuts unthreaded about 1/2" then the nut and stud just spun free. I'm guessing the weld that holds the stud broke loose. I cannot get the nut to tighten again. I've tried putting a Vice Grip on the tip of the stud, but the nut is just too tight. It's rusted kind of bad. Anyone have a suggestion on how to fix this?
