Upper Rear Shock stud stripped - over torque
Sir, Just joined. Missed the all caps "CAUTION-DON'T OVERTIGHTEN." And, I misread the Haynes manual and tried to put 77lbs on the upper mount. Now the stud is stripped. Bracket is riveted to the frame and I cannot get the nut to back off the stud. Do you or anyone else know how to get it off now. I think if I could get the nut off, I could build it up with a couple of washers and use remaining threads on the end of the stud.
Otherwise it looks like have to grind off the bracket and fit something new in place.
ideas?
