I have a ‘96 LeSabre that needs subframe bushings replaced. The problem I’m having is that there is one bushing completely gone but the bolt has broken off but it’s still attached to the fixed nut inside the subframe. I need some advice on how to get this bolt out without breaking it further or breaking the spot weld that holds the nut in place. Should I spend a few days soaking the bolt with Kroil before attempting to remove it. I wish I could attach photos. Any help would be appreciated. Thank you.
If you read the Read this first post near the top of the topic list you will find instructions for photos and videos.
Heat. Lots of heat. And cursing. Plenty of that.
When you've had enough, weld a nut to the broken bolt.
In addition to heat, another method is to drill into the bolt with a special bolt extractor set.
I haven’t used this one just googled it, something like this: https://a.co/d/aRjqUuQ

I've never had much luck pulling a rabbit out of that particular hat. In fact I just tried it a few days ago on some severely weathered and rusted capscrews. That trick never works...

You mean specifically in rusted bolts?
Never had much luck with bolt or screw extractors in general. (Unless you define success as producing lots of cursing.) In this case there was enough still sticking out that I could get them to start turning using a hammer and a drift, then grab with a vise grip. Best way when possible is to weld a nut onto the busted fastener.
They require some skill and finesse. When used properly the can be the quickest method.
Also, extractors vary greatly in quality.
what about drilling a hole (using a drill bit suited for metal) into the bolt to loosen it that way then easy out with a pair of pliers once you have a grip on it?
