I am looking at trying to get this bolt out, I cut it on both sides, and I have about an inch on one side just so i have something to hammer on.

I have tried a stupid amount of heat already, and that didnt even get it to move.... i would like to find a solution that I could soak it in that would start attacking the rust in there, and possibly drill a relief hole in the center of the knuckle for that solution.

Meanwhile I will be cutting off every cradle bolt mount with a sawzall, 10 cuts, they each take about 10 mins each........

Have a machine shop press it out?

I guess BFH 2 people, and ALOT more heat would be the answer I guess.

You might try an air chisel, Sometimes rattling it for a while will break the rust loose after soaking.

Be a bit careful using a lot of heat on suspension conponents. You could alter the heat treatment, and thus the strength, of the part.

Too late now, but I generally find that not cutting off the head, putting an impact gun on it, and rattling away with penetrating oil on it will eventually let it turn. As someone mentioned, an air chisel, or any other way of vibrating it combined with soaking it should do it.

If you haven't tried it already, go get a can of "PB Blast" and soak that sucker good. Let it sit for an hour or so, and soak it again. Then soak it again overnight. This stuff REALLY does work amazingly well in my experience. I've had bolts that didn't move at all suddenly come loose like they're in butter. Definitely can't hurt anything...

It is very hard to use PB on the entire length of the bolt...

After the nut comes off I usually put a long ass pipe on the end and try to work the bolt back and forth. I used a jack handle one time and that was barely enough. It got the job done but an extra foot would have really helped. Once you get it to turn at all, lube the hell out of it and continue to rotate in either direction until it loosens up.

Yes, or use a strong C-clamp on it. Use a socket just a bit larger than the bolt diameter on one end then your C-clamp on the exposed end and press it through. Maybe you've done the same on rear brake calipers, socket over e-brake actuator and compress the piston in with C-clamp.

Now, you said that you had about an inch left on one end, does it have threads? Can you put the nut back on and "pull" the bolt through by tightening down on the nut? Instead of pressing it through with a c-clamp, you would be pulling it through.

I should have tried twisting it out... I just didnt have it in car or anything, would have been hard.
