I don't see where anyone mentioned the lock pin that holds the king pin in the axle. It might be covered with grease, and therefore is easy to miss if you don't know about it. The pin is tapered with a nut on one end, with the other end slightly rounded and recessed in the axle. You drive the pin out then you can drive the king pin out of the axle. Support the axle as close to the spindle as you can get, so the springs don't absorb the hammer blows while you pound on the king pin. If the king pin is frozen in the axle, then you will need to take the axle to a shop that has a press large enough to press the pin out of the axle. The new bushings are either honed or reamed to fit the new pins, although some light-duty king pin sets have "pre-fitted" bushings that work. If you are doing this yourself, make sure you align the grease ports in the bushings with the grease hole in the spindle. Otherwise you new pins and bushings won't last very long.
