If there isn't any noises when you putt the foot off the gas, I would think that it isn't something to do whith the wheels.

Can you recreate the same noise while accelerating with the car parked???

I have my mech look at the Belt Tensioner and the pully.

Yep I can recreate the noise when I start from Stop. But when the car is neutral and stopped and I step on the Gas there is no problem. It comes only when the Car is moving.

Another thing.. the noise is like a airplane Drone, like a Single engine Prop plane, only the pitch is higher.

It come between 0 to 5 and 5 to 10 mph. when the Engine RMP is like 2000 or so.
