Here are the three categories of bevel box:

1) Quiet when new - remains quiet
2) Quiet when new - gets noisy over time then stays noisy
3) Noisy when new - stays noisy

I don't think that anyone has come up with a proven way to reverse the noisiness except by swapping out the BB and hoping that you get a category 1 unit.

p.s. Mine seems to be cat 1 (so far) - so they do exist!
