You can try jacking the car up and spinning the wheels by hand while holding the spring on the strut. If you feel a vibration then its another bearing.

Other than that, I'd kinda have to be there to help diag the problem more.

I had a humming, turned out to be back wheel bearings. They did not set a abs code like the front normally does.

With most front end noises, the sound comes from the opposite side of the issue.

It could be the differential or axle making the noise if its on the passenger side.

Does it get louder with RPM or is it consistant?
