07 Mountaineer - Slight Vibration in Steering Wheel
 

I just purchased a used 2007 Mountaineer Premier AWD V8 with 31K miles. I have a question.
When I accelerate from stand still, I have a very slight vibration in the steering wheel right around 2000rpm. Once I let off the accelerator, it goes away. Is this normal? It only feel is in 2nd and 3rd gear and do not feel anything on the highway.. Smooth as butter.
Does is have something to do with the AWD system powering the front wheels during acceleration? If I accelerate once moving (passing on the highway) I don't feel it.

Thanks a lot!

Tire maybe out of balance. Maybe.
