I have done 4200 miles in my car and the bevel box is incredibly quiet.
Unfortunately after my European trip in the summer there was oil over the outside of the bevel box, I thought from the breather so did my dealer until he investigated further and it is the front oil seal that is leaking, and he has to change the entire bevel box which is some what disappointing. He says there are no service instructions for the bevel box and is awaiting a replacement from the factory.
