How to tell if your differential needs bearings replacement?

Characteristic noise from differential/transmission occurs during acceleration and coast (engine breaking). To distinguish differential bearing noise from wheel bearing noise steer left-right like you are warming up tires for the race.
If the noise changes its intensity than it is a wheel bearing. If intensity of the noise remains the same, that means differential bearings needs to be replaced.
