you need to isolate the noise so you can tell if it is the wheels/drive train or the motor (IE vacuum line, bearing on water pump/AC/Idler pulley...).

The easiest way to do this maybe not the safest is....

Open road, drive the car until the car makes the noise, take it out of gear and coast, if the noise still there? Now turn the motor off, careful not to lock the wheel and crash. If the noise is still there, it's the wheel bearings.

Aside from all of this, it is most likely the wheel bearings anyway. The right rear is know to go out repeatedly for some reason. If it is in the early stages, a visual inspection will not reveal a fault. I have been through two of them already.
