Broken King Pin help...
He guys so this past weekend I was trying to take out the driver side king pin and start my axle rebuild. I ended up snapping off half of the cone. Do you guys have any suggestions for getting out the other half with out screwing up the threads.

Clean the whole thing spotless.

Start soaking the Kroil (or=) into it from both sides at least a day.
Get a big nut to weld to the remains of the cone and burn that mother on hot, but don't heat the Knuckle: get the nut centered the best you can, perfectly is about right.
When everything is cold again re-soak the threads with penetrating oil another day or two:rolleyes:
Heat the Knuckle around the threads go through up to about blue should be enough (don't heat the KP) then put a 3/4" impact gun on the nut welded to the KP and make sure you are going the right way!
If it breaks again the real fun starts! If it moves apply more oil don't breathe the smoke and keep going.... If it starts to bind reverse the impact wrench and flood the oil top and bottom, make a rev, then reverse and power it out.

Oh and good luck:beer:

How did you do; Did you get it out?

Yep, I ended up welding a bolt that I stole off one of the tanks from work in stride what was left of the broken king pin, took a few smacks with a hammer then tried taking it out. Came out easy as pie. Now I just need to do the other side and figure out how to do the bottoms and I am ready for rebuild.
