Wheel noise when above 30mph but goes on left turn?

Yes, probably wheel bearing.
Jack up the front left wheel and give it a spin, if the bearing is worn it will sound/feel rough.
Grip the wheel top and bottom and rock it in and out, any free play would also suggest wheel bearing.
Repeat tests on right front wheel.
Remember to use a stand as well as the car jack for safety.
