The humming starts out low & get progressively louder. It temporarely goes away at speeds above 40mph or if the brake is applied or steering wheel is jiggled or in making a turn.
May at time not be heard for a couple of days then returns.

    Tough one.. I'm guessing that you have a wheel bearing failing. Does it 'get progressively louder' as speed increases or does it increase as time goes by, regardless of speed? Do you hear it when at standstill?

    I appreciate your response. I've been told that if it were a wheel bearing issue the noise would be there consistently. Is that true? The noise surfaces after driving the car for several miles (4-10miles )at lower speeds - around 30-40 mph.
    As I mentioned it seems to go away at speeds above 40mph. Not audible during highway driving. Thank you for any input. Schedule to take it in on Fri. - if we can duplicate the sounds.

    This or a simular noise was present in my daughter's 2002 corolla LE and the mechanic change the main belt (serpintein?) pully & tensioner and fixed the problem. He charged me $400 for doing that and troubleshouting to find this problem.

    From what you describe I think it is a tire wear noise..... have them inspect the tires and the alignment...it may be remotely possible the blower motor has something lodged inside the fan cage, and that would be a noise that will be there even at idle.

    Than you all. Turns out , as I suspected, to be the breaks . Driver's side was not releasing the tire to spin freely, thus the noise at the lower speeds. Replace both front calipers hoses & pads. Curious though, why there's a shhhh noise when applying brakes now? Some one suggested there's a break in period. Is that correct?
