[QUOTE="biglou, post: 428978"] Dan-I think you could do this, or a reasonably good mechanic could do it for you. Here is my input: Take a center punch and tap it on the face of the broken bolt shank near the perimeter. Tap straight in on it to make a divot. Then, angle the punch and see if you can tap it counterclockwise. If it won't move after a few forceful taps, stop right there. Next thing to do is to take the center punch and tap a recess into the center of the face of the shank. Then, obtain a quality EZ-Out and the proper sized drill bit for it. Looks like you have about 1/4-5/16" of threaded shank broken off in there. Drill a hole in the dead center of the shank to a depth of about 1/4" and try the EZ-Out. Hold the EZ-Out with a pair of needle nosed vice grips (clamp them as tight as you can) and tap it firmly into the hole. Then, tap and apply a ccw twist to the vice grips at the same time. Tap and turn, tap and turn. Be very, very careful not to break the EZ-Out off. These things are harder than a Caddilac axle and getting a broken chunk of one removed is not fun. Using the divot mark you made near the perimeter before as a reference, see if it is turning. Usually, once it breaks free and starts to turn, it's very easy to walk it out the rest of the way. If it isn't turning, time to break out the propane torch. Use some contact cleaner to remove as much oil residue from the area as you can, and then heat the area immediately around the bolt for about 10-15 seconds. This will release any loctite hold that is still in place on the original bolt threads. Then, very quickly, reinsert the EZ-Out and do the tap and turn thing. This should get it. If you feel comfortable with doing this, give it a shot. If you start to get into trouble and it looks like you are going to "waller out" the bolt or the threads, stop and take it to a shop. Better to stop before you do irrepairable damage. If you do get it out, once things cool off, clean the threads with some contact cleaner before installing your new bolt. This will help the loctite on the new bolt do its thing better than if there is any oil residue left over in the threads. Good luck. If you wanna drive that thing up to KC next weekend, I'll take it out for ya, and then we can go ride! :) [/QUOTE]
