Hey, Something is making a 'droneing' slight rumbling noise toward the rear of the car when i hit about 25mph plus. It increases in volume as i increase speed, am leaning towards bearing as the sound completey goes away when i go through a right hand bend. Which wheel should i be looking at if it disappears on right hand turns?? rear behind driver or rear behind passenger. Going into audi tomorrow for a diagnosis check, if i can point them in the right direction it will speed things up. Thanks for any advice.
