I have found loose rudder hinges on other planes as well. On mine, I pressed in a new bronze bushing. For some reason it was a bit tighter than the original when new. Once pressed in, the 1/4 dowel on the rudder would no longer just slide in. This turned out to be a good thing. By swinging the rudder while working it down, I got the rudder back on even though I had a slight interference fit in that upper bushing. Just as with the larger hinge pins, by removing the ability of the 1/4 inch to get hammered back and forth against the bushing, wear has been eliminated. The replacement now has around 800 hours on it. As part of my preflight routine I grab the top of the rudder and shake it side to side to make sure the bearing hasn't developed any play. Longer bushings are a good idea if they fit well. Another option is to machine some from stock and ream them undersize since the bolt/dowels are under 0.25" as well. I haven't had the need to go to that extreme though. Chris, Thanks. I have access to a lathe and I have considered turning tighter bushings - but first, I gotta get more info on my wiggly tail.
