Is it impossible to have quiet Richmonds ?? ... No, its not impossible.
Can you fix the whine ?? ... Not really. You could re-set them, but that is going to be hit or miss too. Once they have been heat cycled and have had a few miles on them, its near impossible after they have been work hardend. You could start by changing out to a straight weight 140 gear lube... but... there is no much else you can do.
If you found the right guy... he might be able to quiet them down, but I doubt they will become silent. The biggest problem is finding that one guy that knows and understands the black art of setting up a quiet set of gears. One hint... he'll be the guy that will split hairs over a 0.0005 to 0.001" pinion depth change before he is satified.

yeah gear whine will be there with richmond gears ....i have 4.56 in mine and got it to quiet down a little with some thicker lube ...but it will on average be there with bigger gears.

Verdad Gallardo I have Richmonds in mine and they whine, but I have dumped oval mufflers off of the header collectors, so it drowns it out pretty good. As long as they aren't clunking or grinding, you'll be okay.
