Wheel bearing, not gone but on its way out so no wobble yet.
It is the offside wheel by the way because when you turn left, the off side pressure is relieved.
It does sound like a wheel bearing. However, turning also puts the suspension under strain and this could cause either rumbling or vibration. In a Civic I owned a worn strut made a popping sound on turning left.
You will know if its related to wheel because the noise will change with the speed of the car.
