How do i get a siezed up king pin and remove it from the front axel. the nut is off, ive tried spinning it and it doesnt turn, ive tried pounding on it ( moves slightly and i mean very slightly ), i heated up the axel with a torch ( that helped but still very very hard to move). i do not know what else to do.

get a 5/8 fine bolt or what ever one fits your kingpin threads and beat it out with a hammer. Have had to heat the axle boss once or twice.

If there is any way at all you can rig it up to fit squarely in a press and push it out that way you will see it come out much smoother than beating it with a hammer... just be very careful because there won't be much meat on the axle boss or spindle sitting on whatever you block it up with, and if it isn't on it square you could shoot something out of there pretty hard once you get lots of pressure on it....and maybe make sure you don't still have a set screw in the boss...some axles have a set screw jamming against the kingpin that you can't even see until you push the spindle all the way forward.

Loose is when you hit the wall with the rear of the
car, tight is when you hit the wall with the front of
the car. Horsepower is how fast you hit the wall and
torque is how far you move the wall.

Soak it in Kroil or Mouse Milk and let it set for a day....It will come out with little effort afterwards.

ok, i dont have a press nor do any of my friends and i dont have any Kroil or Mouse milk. I dont like the bolt idea because theres a chance to wreck threads. I used a 5/8" socket that fits through the spindle bushing and the axle and it seemed to work well when using that and a hammer as far as not wrecking anything.  

Does anyone use the freeze spray on things like this?    Works pretty good on stuck motorcycle bolts. 

I was going to say, but pretty sure your freezer isnt large enff to fit he axle in, I dunno could be? nor do I know what part of the U.S. your in, you could send it here and i can definetly get it below 10 degrees for ya, it might be a little warm by the time i send it back, lol  with that being said, i have commonly taken stubborn birdcage bearings out by simply placing the carrier in the freezer over night , what have you, then heating the aluminum with a small torch  it will absorb the heat quicker, then the bearing virtually falls out with a small tap,  im not sure this will work for ya, but before caveman pounding the crap outa it maybe it is worth a try, you might have to east severl sundays at the local dairy queen to convince them to leave your axle in thier freezer? lol,  its not like that is a bad thing, and hell, you can enjoy a nice bowl of icecream (lutenant dan) before you bash the shit outa it?  maybe sponsorship after 10,000 bannanna splits?

Several companies make similar products, but almost every auto parts store carries something similar to this:

You can also turn a can of computer air duster upside down in a pinch.    If you have access to cheap dry ice,  use that to shrink the kingpin

freeze it for a day then heat with a torch 

Buy you some Kroil or Mouse milk for situations like this. I've been in aviation for over 20 years and there is nothing like disassembling landing gear that's subject to the worst enviroment you can think of with parts that cost more than your house. Soak it with Kroil or Mouse Milk and presto! Kroil is advertised as the "oil that creeps" and can soak into a 1/1,000,000 of an inch "gap"!

You're worried about ruining the threads from hitting a bolt with a hammer?  1) A kingpin is hardened and the threads will be tough enough to handle it.  2) How much is a kingpin?  Every shop I've ever been in has kingpins laying around somewhere.  If it's already coming out that hard it's probably junk already....whack the sumbitch!

do it in the dirt

Also, invest in a good heavy brass or copper hammer....
