When traveling it sound like a gas powered airplane noise. Its not the transmission because its a steady sound, not changing when gears do. Changed the R/H front wheel hub where the noise sounded like it was coming from. Rotated tires. Noise still there. Yet when I jack the front end up and go around 45 mph the is no noise, but I do feel a vibration during accelaration. I'm just puzzled why the noise isn't there while the car is jacked up ?

It could be the left side hub, or all 4 tires could be cupped and making noise.
