5th wheel servo noise

Out of curiosity did you disconnect the arm and see where it centers itself? May just be able to adjust trim, may need to re center the horn on the servo?

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

Servo buzzing was caused by..... 5th wheel micro switch jamming! I was testing the function and realized why is there no latching and unlatching sound when couple the trailer? So the servo looked fine, no interference or binding but was actually just squeezing the trailer pin which was stopped by the micro switch lever. Took it apart, cleaned and lube. Works fine now.
For some reason, something tells me I've read about guys cursing that switch on this site??? Any other system available out there to replace this style of switch?

Thanks for input guys
