My 2003 camry just started making a sort of humming noise coming from the front of the car but it only starts when you reach about 55mph. Once cruising at highway speeds for a while it seems to drone away. I haven't been able to find out exactly where it's coming from, it kind of sounds like near the left tire. I was checking to see if anyone here might have some advice or have had the same problem and knows what it is before I take it to the dealership. Thanks in advance!
