Front Right Resonanating Noise
I have a '20 E53 that I purchased this spring. The car has reasonably worn PZ4's and soon developed a sort of humming or resonance out of the front right axle. It's difficult to describe, but it comes across as a mechanical hum that resonates in and out at higher speeds. It seems to be worse in dry/higher grip surfaces or with the car at lower ride heights. Seems to come on a bit more in straight lines than in curves but is present at times in corners. Probably has something to do with road camber and flat vs slightly troughed pavement. I've a brand new set of balanced tires and an alignment done but can feel it a tiny amount in the steering. The rim was checked for bend during the tire install at a good tire shop I trust. Mercedes also had a look at that rim.
Oddly, I've had wheel bearings and drive joints go in my other two vehicles on the front right, so I've some recent experience with this. I can only presume pothole prevalence is worse near the curb! You can' dodge tall of them!
My concern is that the noise is so subtle that I am pretty sure the dealer will say, 'nope, nothing wrong there'.
I'm thinking this could be wheel bearing, front diff exit bearing or CV/drive joint.
Has anybody had failure of these? What was the behavior of the noise/feel?

I know there is something wrong with your front wheel bearing or maybe the CV. If the sound does not go away then that is your bearing but if you only hear it when you turn, then its you CV.
