Started making a loud humming noise on the road. I have no alerts on the OnStar diagnosis, the noise is not there when I am at idle or low speed. This just started all of a sudden

My car is making a noise, I think its a bearing but the garage said it was the rear. When I am going down the road it makes a humming noise, when I turn the wheel to the left the noise gets louder, when I turn it to the right there is no noise. I don't know what it is and I would hate to have to put a new rear in my car. Do you have any ideas or ways I can pin point what it is?

There is a way to tell if it's the bearing. From what you say though by turning the noise change's that is usually the front wheel bearing are you sure it's the rear?Also do you have a jack and jack stand's?

Not sure if its front or rear. Have jack and jack stands. How could you tell if it was the rear?

Let's start in the rear jack up the rear of the car with the car in park and the front wheels blocked. So that the rear wheels are off the ground. Make sure the wheels are securely blocked and your on a flat level surface. Then put the car in neutral then go to each rear wheel and spin it as fast as you can with your hand. See if you can hear any bearing noise also hold the rear suspension on each side while spining the both rear tire's. Compare each side to each other. Let me know what you find. If you have a bad bearing you should be able to feel it or hear it.
