Bolt snapped. Must've been a bad bolt because I was only using a 3/8th drive Craftsman and I'm not that strong. It's located in the worst of spots, in the rear on the arm that comes out of the chassis, where the body bolts back on. It's sticking out maybe 2 or 3 mm, and I only have about 7 or 8 mm to reach in.
How screwed am I? I want to avoid removing the body again because the chassis was kind of messed up making it incredibly difficult to bolt it back up on the heater channel bolts (rest of the stuff went on easy)

Once I snapped a bolt in a bad spot on a 72 Chevy Truck I had....I swear I did this not making it up. I used JB Weld to put it back together and then I used Aerokroil to soak it in and took it out w/vice grips. I let the JB Weld cure for the entire 24-48 hrs b/4 I messed with it.

Matter of fact I kept the bolt and I saw it a couple of weeks ago. If I can find it again I will take a pic of it and post it.

Can you place a nut over it and fill it with a MIG welder?

I have used this technique several times. The heat generated usually loosens the remaining bolt.

Put a flat washer over the stub and weld it to the broken bolt. Next, place a 3/8 nut on top of the just welded washer, and wait a minute for the heat to absorb into the casting around the broken bolt, then turn it out. This usually works. It can be done to a bolt that breaks flush. Good luck!

JB Weld held strong enough for you to get the bolt out? Amazing! I wouldn't think it would hold strong enough to take more torque than the busted bolt could.
I threw an ad on craigslist, I'll see if I can get someone over to try the MIG deal. Thanks for the suggestions, guys!

Yes, but I let it cure at least the 24 hrs is says to. I'll look for the bolt tomorrow.

By the way, if someone is local to me and they can help me out with this, I'd really appreciate it (and compensate for it, too) Wink

If you have to reach in to get to it, you'll have a heck of a time getting a welder in there. I'd try soaking with Kroil oil or PB Blaster for a couple day's and trying a good set of vise grips.

x2. Put a nut on the end, looks like you could even engage a thread or two, then weld the inside of the nut to the stud. This is the way that works most consistently for me. I've played around with ez-outs in the past and never had much luck. Once I got a welder and learned this method I never even considered using an ez out again.

Hey guys. Since I didn't have a welder and I seemed to scare everyone who emailed me about it on craigslist off, I decided to take a simpler approach. I lifted the body up a bit and just drilled the bolt out, stuck a nut underneath, and that was that. Took ten minutes and it was good to go again.

You have to heat the bolt with a oxy acetylene torch 1/4 white hot tip and make the bolt read not the threaded When this happens the bolt will expand and crush the rust.
Then soak it - maybe wire feed a turnable washer to it or draw file a slot with a hack saw and turn it out with a screwdriver

Damn,,, I am on narcotics from a back injury-
After heating let it cool completely and soak it with blaster -two hours - maybe even some ice on the bolt.

either way he got it out...


...welding a nut to it is much faster and does the exact same..it's common sense. if he doesn't have a oxy/ace then he isn't loosen ing anything!


the heat created from the welder is going to loosen it up..so no need to create a slot and wled a flat washer in if you can weld a nut to it yes?
