3B's right, the ball studs use a tapered shaft. To get them off you have to drill out the center and drive them out. Plus side is they still make them ($$) and they are available with threads that use a castle nut and cotter pin.
You ought to get end kits for the old style tie rods as well. From what I could find, modern tie rod ends with the correct tapered shaft are not available for the 3/4ton.
If you get into the kingpins, that's another story. They really need to be taken to a shop,pressed out, and line bored.
