humming noise increases in pitch and volume w/ speed

My mother -in -law has a 01 lincoln continental ( I know, wrong forum) it has a humming noise in the left rear that increases in pitch and volume w/ speed. It goes away when I turn the wheel to the left but returns as soon as the car returns to straight. Starts at 20mph and doesnt stop after that. I raised the car and checked for wobble, bearings and pulled the wheels and looked for anything rubbing and fouund nothing. Rotated tires and has same noise ?? Thanks in advance.

Have you raised it on stands and run it to listen for the location?

Sounds like wheel bearing knackered and noise disappears when load is transferred when you turn wheel .
