Take it out for a long cruise and when you bring it home pull the fill plug while it is still hot from driving and let the hot lube drain out into a pan. Once it stops dripping COMPLETLY put the plug back in and see if that fixes the leak from the wheel bearing.
Does it leak from both sides or only one side?
