    I would suggest that the eratic movement of your rig (i.e. video in post 150) is caused by using a CV joint, and not a standard UJ joint.
    IMO, CV joints are not designed to take axial load, and the shaft probably bottoming out inside the fixture.
    This will put abnormal loads on the motors, etc, and any perceived movment will not be a true effect of any adjustments.
    The fact that I saw you were using it, meant I had to read all of your threads posts to see if anybody else mentioned it.
