Why the heck is this happening ? I didn't over-tighten the bolt! why the heck would these threads strip ? This is the second time this happened to me! . I always use the freaking torque wrench!
Wow. I believe the torque spec for those studs is only about 11 ft/lbs, and the cap nuts is about 8 ft/lbs, which is very light and shouldn't have resulted in stripped threads. Was the VCG replaced before, and is it possible that someone else may have overtightened the nuts/studs and weakened the threads in the process?
