Like title says. But, I only get this humming when I stomp on it. It will hum for 2-3 seconds when the torque is at it peak. Then it abruptly stops. Wheel speed seams to have nothing to do with it. It is directly related to stomp'en on the go pedel.

So I don't THINK it is something like a UV joint... Oh, the humming does remind me of the traction control when it's operating, but that is typicly when ya do a hard accel while turning. This happens any time I stomp it.


Any help?

Thanks
