I have had this problem when replacing the front axle on my special with a Big 7 axle which had been sitting in a breaker's yard for a long time.... I needed to get the axle to dull red heat with an Oxy Acetylene torch before I could knock the radius arm bolts out with a big copper mallet. But if you know someone with a hydraulic press, you might be able to get them pressed out with a lot less heat input. I had to put the torch on the kingpin eyes too before the king pins would come out, didn't need to get them anywhere near red heat though.
