I have a Whuh-Whuh-Whuh pulsating noise in my 2005 subaru legacy GT. It is like a low "rubbing" noise. The noise speeds up with increased speed and slows down when going slower. I replaced a wheel bearing a few months back and the noise sounds different than when I had a bad wheel bearing because with the bad wheel bearing the noise was a constant "whirring" whereas now the noise is a whuh-whuh-whuh pulsating noise. I can feel the vibrations under the drivers side and through the gas pedal. Any ideas? Could it be a wheel bearing even though it is a pulsating noise and not constant? Rotors?
