I've recently noticed a whining sound coming from the case. Frequency increases with speed, most noticeable at speeds from 45 on up. Not loud, but I can make it louder by moving the case shifter forward or back 1/8 inch. Is this a noise I should worry about and if so, what is it? Far is I know it's never had anything done to it. 240,000 miles, NP208.

Thanks!
