So I have had this expedition for over a year now and just about every time i drive it i have music playing and dont pay no mind to any sounds while driving.I drove while ago without music and i wasn't sure if the tires have louder road noise then my Accord and Altima or is it a wheel bearing.I was not used to driving a vehicle that has sound other then the engine or exhaust (v6 altima... Do you guys have louder tires then your reg passenger cars or should a be worried about a wheel bearing ?
