I'm not ready to tear it apart just yet.Â* From what I have seen reading

Whatever I have I am pretty sure is missing something.Â* Driving the
front (or the rear) is 1:1 with the opposing side.Â* Seems like the
rotational part may just be one piece.



Never mind. Sent it back. Not worth my time to screw with an incomplete
POS.
