I'm with BritTwit and FastEddie, while you have it apart anyway I would definitely compare the length of the bearing spacer to the distance between the bearing stops in the hub. Too short (or too long) and it's going to put increased lateral load on the bearings and overheat them causing premature failure.
I'm sure Stanley Lynde will do this when it's time to reassemble the wheel. He said it should have been checked when it was assembled the first time.

If that is the case the wheel shouldn't have been wobbling around, only the sprocket. Or has the other bearing blown as well?
The other bearings are good. To be clear, it wasn't a consistent wobble. More like intermittent tugs left and right.
cliffa said:It may be a trick of the light, but those cush drive bushes look to be inserted at different heights, one at least appears to be proud, while the other are recessed. I guess that could also cause runout on the sprocket carrier and load the bearing due to misalignment if it can't seat fully on the hub. (Especially if it happens to get overtightened)
The cush drive rubbers float. I can push them in completely with my finger so I don't think that was a problem.
