Any tricks to remove a broken bolt with limited access?

[JBird_Cobra]

So I have to replace a few speed sensors on my gf's Jeep before I can go out and celebrate the 4th. Of course the bolt broke on the last one and I can't get it out. There's almost no access to the bolt due to the control arms, shocks, brakes, etc. Anyone have a trick to get it out?.. I can't get a drill in there, I can't get pliers or vicegrips in there, etc.

The car also won't start until the bolt is back in so it's stuck... I just wanted to ask before I try everything I can. I'll check back in a bit so thanks in advance for any ideas.

Well if you have a welder handy you can take a half inch nut and fill it in.

Or the welder if you've got it.

Yeah I have neither ha... that's why I'm stuck. The only option I can think of is to remove the rear hub and hopefully have access to it?..

yeah pull the whole drum off and it should be accessible.

Sucks.

Bolt extractor but you need to get a drill to it. I think the easiest/cheapest rout is to take it apart.

I would soak it with PB Blaster or whatever penetrating oil you prefer, tap it in the CENTER with a center punch and try to use a chisel or pointed punch to roatate it out. Tapping the outside edge on an angle to try to rotate it. I've seen it work on a crank bolt in a honda more than once. You may get lucky.

+1 on the PB Blaster and centerpunch. A propane torch might help.

Then a 90 degree drill and left hand twist drill bit.

There was not enough room for anything other than a box end wrench in there... maybe 1/2" of space for anything because I could not come from directly behind it.

I didn't have many options but I cut into it a bit with a Dremel and then used JB Weld to 're-attach' the bolt head. I got real lucky and it backed out like that.

Duct tape would have done the job
