I've thought about this and done some things like using Red Line 75W140 gear oil in the bevel box. It helps but not by much. Mine was never a real problem as the whine of it did not drown out the spinning of the drive shaft, the belt noise of just moving air, the valves up front, the whine of the transmission and now that I have the camshaft cover set off I can hear the noise of that!
I've said it before, but it bears repeating: I get worried when I don't hear something. It either broke or fell off. I also get worried when one thing starts dominating the action.
It's just a noisy car!
What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.
