My B2710 makes a kind of whirring noise that gets worse and louder the faster I go. It is coming from somewhere around the front right wheel. I opened up the housing and saw that the main wheel bearing is fine, and the gears I can see look great too. The noise is somewhat intermittent, but quite frequent, and happens in forward or reverse. It's been like this for over a year, but it is slowly getting worse. Any ideas where it is coming from? I don't want to just start taking everything apart I can get some advice on where to look.
