Hi can anybody tell me what the strange noise i have coming from what sounds like the wheel/wheels? ie when i startd driving im getting a strange noise from the wheels, well i think it is as could it be wheel bearings? also when you slow down its more noticeable and just sounds like a whining noise< if anybody can tell me what it could be and also a possible price to fix? if helps im getting no juddering over 70mph and the steering seems all ok..

Hope somebody can help
