Makes a noise when the car in moving and the noise increses with the speed. No virbrations just loud noise coming from the rear I think? Tire?
Could be. Tires can get noisy when the tread starts getting low. Saturns aren’t known as vehicles that dampen road noise well and yours could be letting you hear the tires on the road.
It’s also possible that you have either an improperly worn tire due to a worn suspension component (or three or four) or even a bad bearing. When was the last time you had the chassis looked at?
Lastly, have you checked the tires’ air pressure?
