I have just removed the radius arms from the front axle, they were not that tight, but they have obviously been off before, the pins that pass through the axles are both damaged. The NS one has had the thread sheared off flush with the front of the axle beam, this has been badly drilled and replaced by a bolt. The OS one the threads are completely stripped. My thoughts are that I should cut the pin back flush with the axle, counter drill and tap the pin and replace with a bolt. Has anyone done something similar before or have any better ideas.
Nick, my first action would be to talk to Tony Betts about the possibility of replacement radius arms in good nick. Only if these are not available would I attempt a decent repair. There isn't usually too much of a shortage of Ruby bits.
