While it doesn't seem likely, I think it is easier to pull the radial wheel and check that than go after the idler wheels and plate under the pedestal right now. You could check to see if the key is still there in the rudder post and hasn't become partially sheared or worn in some way from the radial wheel having been loose in the past?
