broke bolt off in steering knuckle- advice?

'01 DBL cab 3.4L 4x4 w/ OME 3" lift

I was changing out my passenger sided LBJ and one of the 4 14mm bolts had seized in the steering knuckle and broke the head off.

While the spindle assembly is still connected to the UCA,
I heated the remaining bolt sticking out 5x dousing with PB blaster each time, then tried vice grips, didn't budge. I welded an over sized nut onto the remaining bolt, doused with PB blaster and tried to remove it, the bolt broke a 2nd time.

Now should I:
1) buy an OEM steering knuckle ($100-200 unless someone on TW has a used part to sell - Please PM me ASAP, my zip is 63501)
2) have a shop in town try to remove the stud (as i'm really tired of fooling with it! ) ($200-400)
3) go with an aftermarket steering knuckle ($$$$$ )

This is my DD so any input is appreciated!

 

You could drill it and try an easy out on it. Are you using enough heat?Are you getting it red?Anything left to grab?

 

I heated it with MAPP gas and when I welded the nut on it was glowing red!
there is still about 1/2" of the bolt still sticking out.

I think I found a replacement knuckle for $50 - planning on getting it tonight and swapping it out Sat morning.

Then I can fool with drilling out/removing the old bolt at my leisure & on the workbench.

 

Sounds like a good plan!

 

So, after heating, PB Blaster, welding a nut on the remaining threads and even drilling the bolt out - all failed
I also noticed that the aftermarket (lifetime warranty axle shaft & CVs) CV boot had a hole. Picked up a new one (warrantied) from O'reilly.
Found a replacement steering knuckle for $50, installed the new front axle shaft, replaced the steering knuckle, put the front wheel on then had Mexican food for lunch!

I'll still take the OEM (for my Taco - the replacement came from a 4Runner) drill out the bolt so it's usable and put in a new upper ball joint, change it out and put the other on the market!

 

Nice job and attitude bower2002. Sounds about as much fun as taking my 96 rusty bed bolts off. Heat the hell out of it and get 3/4 turn. Repeat 20 times. 1 bolt.haha
