loud noise
 

i drive a eg hatch and everytime i drive the car i have a very annoying humming noise that seems to be coming from the rear end of the car. its bin doing it for a while but i have had the car checked out and no one has ever told me there is a prob. i have a 2 1/4" cat back exhaust and the humming is louder than my exhaust at any speed over 80 km/h can anyone help me ive had people say that it might be a wheel bearing???

yes it is

i think it would have to be the wheel bearings it is one of the only bearings on a car that will humm the way you can check is jack ur car up and spinn the back wheels u might not hear it and if u do it will be very quiet they run about 120 if u have disk and 30 if u have drums
