2001 gmc with 20" wheels, when going 20mph and up there is a roar sound with a little vibration in steering wheel. Turning steering wheel while drive doesn't seem to lessen the noise. Could it possibly be a wheel bearing or bad steering linkage?



another question, the fuel gauage reads empty but if you come to a stop and shift to park then it starts to operate and read correctly and later may go back to zero. Is something mechanical hitting a loose wire maybe?
