Pathfinder I
Thank you for sharing your knowledge on this subject. I have removed many broken bolts where a drill and easy out could be used. This method of welding a nut on to a broken stud is new to me and very informative.. Still doing it from above or below the vehicles engine had to be a tough nut to crack. What would some of us do without the kind of knowledge you possess and willing to share it.
I took a picture for you, so as the sat they were flush with the “y” pipe flange. I removed the “y” pipe from under the vehicle to get access to the broken studs. This left me with short threaded stubs of studs. On those I filed the threads so bolts would go back on then locked one bolt against another. 2 of 3 came out with this method with a little coaxing and some penetrating oil. The third is on the far right, after having the spinning nuts welded to it. Grabbed it with vise grips just as it cooled from cherry red and began working back and forth while hitting the joint with the oil. As it eased up to turn, I spun it right on out. Took about 30 min from that point to reassemble the exhaust with new studs and lock bolts.
I’d love to act like these are all my great ideas/tools/products but I’ve been fortunate enough to have most of them shared with me at some point.
