Abstract
A power take off unit includes an input gear, an output gear, and an intermediary gear that cooperate to transfer power from a rotational power source to an operating target. The power take off unit has a control module that biases the intermediary gear relative to the input gear and the output gear to reduce gear rattle vibrations associated with intermeshed tooth looseness.
