Does it sound like wheel bearings or the rear axle?

Have you visually checked your tires for any wear pattern on the inside edges? They may be 'cupping' , and that can cause a noise like a wheel bearing. Just another option to check besides the two you already mentioned.
Got a new tires because of the noise. No visual wear after 300 miles. Noise still the same.
THEN , YES , AS YOU STATED ORIGINALLY , HAVE REAR BEARINGS ETC. CHECKED.
