i got new standard pins and bushings for my daily driver (the original king pins are quite worn, the whole hub can giggle a bit)
according to the service manual, a copper drift and small hammer should be sufficient to push the pin out.... haha funny book

removed the axle from the truck, removed all brake parts and bearings, put it all in a 20 ton press, the king pins are frozen in place, tried hammering a bit with a steel punch, but am concerned the pins will begin to expand.
gave up, put is all back together fixing up the steering linkages and springs and brakes during reassembly, still have giggly wheels tho.

one day i will get an oxygen lance for a different job on my tractor, and i'm hoping to be able to burn the pin out from each side, then i can focus on just the frozen stub of the pin in the center hub assemblies.
