Yeah, I know. Tried the BFH and the Oxy/Acet wrench. Still wouldn't budge. I had a spare set of trunnions about, so I sawed through the bolt on the gaps between the trunnion and the shock arm. It was coming apart one way or another.
Antisieze paste is your friend, or don't you use that either /ubbthreads/images/graemlins/devilgrin.gif
edit: in fact, I couldn't even get the trunnions off the top of the kinpins; even using a vice to try and press the bolt stub out. I think the kingpin dimple rusted fast to the bolt. I think I threw the whole mess in the bin.
