your words state "nut moving" is that "not moving"? or moving around.


I looks like the back thin washer might be the tab washer that should be folded up to the nut to stop it moving,, might be wrong,any way, put a socket on it and try tightening it.see if it moves,


the thing is do you suspect a problem?
