Turning the CIMs 180 degrees made a huge difference. You could literally see space between the CIM output gear and large cluster gear where before they were jammed together tight. I could not see the motor mounting holes out of alignment with the shaft but what else could it be? One of the gearboxes is running quiet and smooth. There is still a little noise coming from the other box and you can see the output shaft and bearing wobble a little. I don't know if this is caused by something internal or runout in the VEX hex bearing but will try to find out tomorrow. It seems both AndyMark and VEX are both having problems with the .5" hex bearings. Neither one has them in stock right now.
