I'm not sure, but it would be very hard to conceive of a quieter hub than Shimano Ultegra. They're only barely audible while freewheeling. I was so used to that that my present wheels (the swarm of angry bees kind) took a little bit of getting used to. But I saw the bright side: it's a much more effective way of letting others on a MUP know I'm coming up behind them.

Even as an atheist I would agree that cutting apart that wheel and paying someone to rebuild it on a different hub would qualify as a sin. With the FSM's guidance and tender mercies the OP could either learn to live with the noise, or at least find a relatively inexpensive replacement wheel that's similar in cost to something like a Shimano hub plus possibly new spokes plus labor.
