Drone noise & mild vib frm mid-rear @ hiwayspeed. Chgd drv shaft assy & frt brgs
What is your question?
Sound varies directly w/ speed,exactly. Never services PTU lube, have 106K miles. Noise is getting louder, is not tire noise. Too loud for a luxury name vehicle! Changing both rear bearings today with concern for this being final fix. I drive approx 600 miles per week. No Leaks at rear observed. Thanks.

Bearings sound like a good place to start. Was my first thought.
