Maybe a wheel bearing -does the sound change when turning in one direction or the other? Could be a belt driven accessory that has a bearing going bad. i.e. alternator, water pump, belt tensioner etc.
when you turn your key and you only hear humming noise, the problem will most likely be that the starter is not engaging the fly wheel, its turning but is not sliding forward to do its job. have the starter check.
Are you sure it is not just tire hum?
This could be caused by worn out ball joints, worn out constant velocity joints (if equipped), bad wheel bearing, worn out steering linkage, loose wheel nuts, cracked rim, worn out sway bar bushings or end links. Most of these are pretty serious, you need to have them checked ASAP. Losing a wheel at highway speed, which some of these can lead to, sucks, trust me I've seen it happen.
r/f wheel bearing. the weight shifts to the left tire when you turn right so if the noise stops its the r/f wheel bearing.
Possibly worn wheel bearings can create a humming or groaning sound.
bad wheel bearings
It's most likely to be a wheel bearing if you jack ur car up an spin each wheel if you hear a rough sound it's a wheel bearing
There could be a few things that can cause this humming sound. It could be the wheel bearings rubbing, it could be the gears rubbing, it could even be coming from the engine pistons.?æ
One would really have to hear it in order to determine for certain. Are there any particular conditions existing in which the humming occurs? Wheel bearings are a possibility.
With each wheel raised, Use both hands, one at 12 o clock position, another at 6 o clock position of the tire/wheel. Shake it, any movements? Should be none. Another way is, when driving, there is a "humming sound", it will get worse if you turn it to the right, or worse if you turn it to the left. The humming sound will go louder. If humming sound is stronger when turning wheel to left, RIGHT BEARING IS BAD. If humming sound is stronger when turning wheel to right LEFT BEARING IS BAD.

Wheel bearing?
It is most likely your front tires and then that woul mean your wheel bearing.
yes it will
The caliper may be hanging and causing the humming sound. I cant type the sound out but it mine made a humming noise as the wheels turned. If I pressed the brakes hard and quickly let go it would stop. I just replaced rotors and brake pads and it is back to normal now.
