Humming Noise From Front End

[Wubbman]

I hear a hum-hum-hum noise at low speeds whenever I'm decelerating. It seems to be coming from the front left wheel. It is just at pronounced when I'm braking. I'm pretty sure its not the CV boots, as I've checked them before and they're fine. Any ideas?

[philbe1]

could it be the wheel bearings? does it sound like parakeets chirping? or maybe its the front rotor is warping.

cv boots don;t make any noise ,broken or not.

It is more than likely a bearing or a tire.

got any more info

It is not a high screatching, just a low pitched 'hum-hum-hum.' It did it today during acceleration as well. I suppose it could be a tire. I had them rotated about two months ago, but this thing has only started in the past few weeks. I posted earlier about the plastic housings descending, could this be a result of rubbing between the wheel and the plastic housings? I'll have to go take a look in awhile.
