[QUOTE="Stoopid Jeep, post: 441585, member: 20049"] Center punch the broken bolt. THIS IS IMPORTANT! Drill as straight as possible and as centered as possible with (about) an ⅛" drill bit, at least ½" into the busted bolt. Once your pilot hole is drilled, use a propane , or map gas torch to heat the broken stud. Once it's glowing a dull read, start squirting penerating oil on it. PB blaster, wd40, atf, doesn't really matter. The oil will probably smoke at first, that's OK. Squirt a little and watch it smoke, squirt a little more and watch it smoke, repeat until it stops smoking. Squirter it a few more times, just for good measure. Let it cool down to room temperature (this is a good opertunity to repeat the process on the rest of the broken bolts. Next you need an easy out kit with a Left handed drill bit (probably ¼"ish) Use the LH drill bit to follow the pilot hole. If you're lucky, the broken bolt will come out with the drill bit.... if not, move to the extraction bit. Use a wrench to twist it into the hole. Apply gentle firm pressure on the wrench and tap the back of the extraction bit with a hammer. If it doesn't budge, turn a little harder and tap a little harder. If it still doesn't budge, go back to the heat/penetrating oil and repeat. ...if that still doesn't work, you might need to move to the next size larger ez out. Repeat all the steps. I was a boat mechanic for 7 years. I have extracted A LOT of broken bolts. This will almost certainly work. You can do this. [/QUOTE]
