Broken Bolt Removal?

I was checking the underside of the jeep and found that the steering box rear mounting bolt was missing. Upon further inspection I found that it was partially there, just snapped off clean. It looks like it snapped right at the bottom of the retained nut inside the frame. At this spot there is no access to the nutted end.

Any ideas for getting it out? I will try and drill it then remove with an EZ Out. I suspect that it is pretty well frozen though and this may prove futile.

Re: Broken Bolt Removal?

do you have access to a torch? if so.. heat that sucker up real good.. will loosen it up some.. then use an ez out.. another thing.. get a punch.. or something.. on the bolt.. and beat it real good with a BFH.. this will also help loosen up the bolt.. then drill and ez out it..

Re: Broken Bolt Removal?

I have tried a bunch of methods, and the one that worked was to drill out the bolt and re-tap it.

Re: Broken Bolt Removal?

As long as I can get to it with my welder, I've never failed by welding a lever arm to it and backing it out.

Re: Broken Bolt Removal?

How solid is the nut mounted in there? I am worried that if I break it loose I will really be screwed! There does not seem to be any access at all unless I cut the front crossmember off.

Re: Broken Bolt Removal?

Soak the shi% out of it with WD40 or some other lubricant a couple times a day for three days. Find a center punch and just before you are ready to punch it lube it again then punch it right in the middle (hard!). What this does besides giving you a center to start drilling is it causes the threads to move a little bit allowing more lubricant into them. After that you get a bit that is about as big around as the divot you put in the bolt with your punch and drill it (go all the way through if possible) then get a bit one size bigger and repeat. and so on an so on. After about the fourth bit the bolt is usually free. If not but an easy out in it (square cut NOT spiral cut) and it should remove that way.

Re: Broken Bolt Removal?

I used the Jeepgod approach. I heated that sucker real good and then used a punch and a BFH. That nut and the remains of the bolt flew off inside the frame. I used a bent coat hanger through the holes you see in your picture to move it to an opening I could get it out. The opening I am talking about is the angled opening back of the sway bar mount. I then taped a self tightening nut and washer together and put it in the same hole. Again I used the bent coat hanger to slide it down to the proper location. It works best if you stick the bent coat hanger in the center of the nut and washer until you get it over the sway bar mount bolts. I used the new bolt to raise the nut and washer up inside the frame. I stuck my little finger through a hole to hold the nut while I got it started. I tightened it as far as I could and then used the impact on it to get it tight. It was not really all that hard and took about 20 minutes.

Re: Broken Bolt Removal?

The posts above give a LOT of good advice!
Just remember that it's not a 'nut' in there ... just a pretty thin sleeve with thread on it's inside bore and if you tap it larger after any or all these suggestons you will then have a VERY thin 'nut' holding yer bracket.
Try to save the old thread sixe and don't go much past 40 ft. lbs. torque to reinstall a new grade 8 bolt.
