I am trying to replace the kingpins in my 51 3800 pickup.I cleaned everything very well and the soaked everything in deep creep and let it sit a day or so.When I went to remove the kingpin locking bolt the nut twisted off.That really didn't bother me cause I figured it would drive out for sure - one less thing to fight ( and the new pins always have new locking bolts). WRONG !!!!!!I used my short BFH and a large punch and its not moving-at all. I even heated the lock only not the axle-let it cool -and went at it again , and again and again. It still has not moved. I have done several sets on kingpins in my time , but this is insane. Anyone have any ideas.
LMD.
