Have a 99 V70 AWd wagon,have been lately getting a thumping noise from under the console area when car is put in gear and given a shot of gas,do not have any other noises,is there a steady bearing under there somewhere,have not had a chance to look at it yet.car runs fine on highway do not feel any vibrations otherwise,also when backing up when brakes are applied,makes a noise that feels like you backed into someone?any help is appreciated
