So... I'm at a loss. It seems to me that once you disconnect the lower linkage connectors, removing the 'axle' bolts should more or less do the trick. But of course it doesn't, and I'm starting to think perhaps there's a special tool required (or maybe just a large bolt of the correct pitch) to thread into and remove the pieces that Vertigo refers to as the swingarm semiaxis.  Anyone had their off?
