I apologize in advance but I cant find anything in this thread that pertains to me. I have a 2017 and I can't get this to work. Does anyone know what pin I should be looking for? Thanks

I am assuming you have a Z-71? If so its probably your locker in the rear end. I've noticied this also and it bugs me but my dad has the same truck I do and his does it also. The locker deactivates over 20 mph and I notice it if i coast down to 20 mph and get back in the throttle a bit. Test that out and let us know if its the same noise.
