Alot of heat , even than they can act like they are glued in , I had to change king pins in My 79 3/4 ton Ford van one side came out like butter the outher side would not move I took it to freinds shop and He had a screw press that We put on the axel and than heated it up and with the help of a 3/4 impact tool and a good smack with a BIG hammer got it to move try putting pressure on it and heating it up HOT with the pressure on it if You could give it a smack she might give it up .
