Isolating a bearing noise (front)

Hi, one bearing is staring to hum going into a turn doesn't change the noise. The tires are good with no cupping. I'm disabled but was a mechanic for many years. That being said what is the easiest way to isolate the noise? Although I believe it's the left front. please include checking the rear also. I shook all the wheels no play is felt. I have been told you can spin the wheel and hold the spring. By doing that i'm told you will feel the roughness of the bearing and none if it is good. Is that true or not? I do have an electric ear I can use also. please keep in mind my flexibility is limited (need hip replaced).
