Noise coming from Front

[sc330i]

Hey!

It is like a humming noise that gets louder the faster you go. It is not based off rpms but rather wheel speed. Also, when you turn to the left the noise stops completely. Once straight or to the right it is there. When it is in neutral the sound is still there. My thoughts are wheel bearing or power steering pump. Anyone have any input?

maybe a frozen caliper or a pad, or even a loose fender liner....

Wheel bearing, assuming by neutral you mean not in gear but the car is still moving.

Just replaced my brakes because that is what I thought it was originally.

Yes- I think it’s a wheel bearing, but the turning left part throws me off.

I’m no engineer, but perhaps the weight transfer when turning changes the force applied to the bearing in such a way that the humming goes away. I suspect with time it will be present when turning as well.

That's the diagnostic tell it is a wheel bearing. When you turn you load up or unload the bearing changing that noise.
