So, working on the Clunker today, but ran into somewhat of a snag. Pulled the rear axle, regreased the bearings, and mounted it back up. only this time, the cone on the freehub side completely disappears into the freehub, making adjustment impossible. What have I don'e wrong? AFAIK all the parts are still there, and a spacer between the cone and the freehub body would make the bearings spin in thin air.

btw it's an older shimano hub from the very early Hyperglide days, it still has uniglide threading. It's a HG-50, for what it's worth.
