I scheduled with Tesla service and took the car in 12/28... my service manager is great, she asked if I wanted to ride with a tech to have them hear the sound...I told her, no need, they'll hear it as soon as they get in... She knew it was a humming sound. They replaced the hub and no more noise... all good again.
Since it was in the shop I also replaced the passenger tail light unit (didn't want to get pulled over for partial brake light / no reverse light)...
Now the only thing I have left is to fix the steering wheel scroll for volume....($300 quoted by Tesla, just not sure I want to spend that right now)
