5th wheel servo noise

[Supermario]

Thanks guys, now that you ask about centering I noticed something. With the truck shut off the servo arm has a position it sits in. When powered up the servo moves slightly to a new position and when in 5th wheel mode it moves again a little closer to the end of hole in the deck plate. I had centered the arm on initial start up but had never cycled through the functions. I think I will try centering the arm while in 5th wheel mode and see what happens.

Thanks guys
