Anyone have experience servicing a Goldtec hub axle, bearings, etc?

Just managed to do it. It took screwing the allen bolts in and lightly tapping with a hammer. Axle comes out with the bearing cassette on the other side.
Stodd I can do this for you when we meet, it has to be done extremely carefully so you don't strip the threads on the axle or bolts.

If you pull the end cap/spacer off first, you can tap the axle out directly without having the bolt in place, which saves stressing the threads. Depending on how hard you hit it to get the bearings out, you might want to consider replacing the bearings while you're at it. Make sure you press the bearings back into the shell by pushing the outer race, as that's the one which is the interference fit.
