As delivered, the ship came with Schempp-Hirth standard brass bushing and brass washer which allows the self-locking nut to be tightened up completely and the rudder will still move freely. Not uncommon to find the brass washer installed upside-down or missing and replaced with a standard washer. In either case, tightening the nut will produce a stiff rudder.

I was a bit amazed that op, provided with necessary knowledge about lower hinge bushing, managed to not get it replaced by proper part, and still get it signed off by AME.
