Yes Im not sure if you have 1 motor, 2 motors, or 4 motors. Didnt really research your particular unit. But if you have more than 1 motor, then they must be in sync for sure. Lippert has decent customer support. They can likely go thru it over the phone. (Unless the actual motors "well gearbox actually" is different). Then you will likely need a tech to do that. Especially if you have 4 motors and the one on top is bad. YIKES-let a tech do that one.
I started with nothing, and still have most of it left
