Bearings ?????

I have a Focus Ghia 1.6i of the year 2000. For a month I notice as a buzz at the right rear wheel that is accentuated in the range of 60-90 km/h. I have uploaded the car and I have proven if the wheel has a slack on the topic of the bearing, but it does not have it. It is possible that even if it has no clearance, it is from the bearing?

thank you

It is possible that it is the bearing, not because of wear but because this gripado, it may also be that you have the stepped wheels.
