Mysterious Front Whirring Sound

[Nina]

Hey folks,

So I first replaced the driver's side front wheel bearing on my 2008 LE Hatchback and that got rid of the loud growling sound but I still heard noises. Then I thought to replace the passenger side wheel bearing to eliminate the continuing noise but it's still there but not as loud. The best way I could describe the existing sound: it's not a howl/growl sound anymore but a whirring type of noise that when decelerating you can hear it like an electrical noise winding down. It's not present when idling or revving in Park so it's not the alternator or water pump but when moving it's present even when coasting in Neutral. The tires are not to blame either. I'm wondering if the CV axles were causing this but that would be more of a clicking sound which I'm not getting.

Any feedback would be awesome
