Yup! If your left bearing was out, it would be more noticeable when you are turning right. The weight shifts into the left side when turning right which loads that bearing and vice versa...
Another give away in front to rear is if you feel the vibration in the seat of the car it’s most likely the rear and if you feel it through the pedals or steering wheel it’s in the front.
Most streets will slightly lean right or left, most people rarely notice as they correct it without thinking... so if you were on a road that leaned left slightly, then the hum would be worse as you are correcting the wheel to the right thus loading up that left bearing...
Glad it’s resolved!
I usually replace mine with timken as they make most OEM wheel bearings and are top notch quality.
