Right turn rumbling noise

[Jeff]

When driving (under power in any gear) in the minivan and I turn the wheel past center going right I hear a rumbling noise that appears to be coming from the left side. My first thought was wheel bearing (the right one was replaced some time ago for a similar problem on left hand turns) but here is the kicker. When I depress the clutch or pull it out of gear while the noise is being made it goes away...axle? That's the only thing I can think off that could be causing it. I can be accelerating of or engine braking and it is still there, until the clutch goes it then it goes away slowly as the transmission slows down.

Is there anything clutch related that could be causing this? Also of note, the faster I am going the louder it is.
