I had a similar wobble with a small gap between the lower roller bearing on the rudder post and the boat tube built into the hull. Noticed it when on the hard for the winter I could rock the rudder by hand and see the bearing move back and forth. I found a large O ring of the correct diameter [believe on McMaster Carr] to just fit around the bearing with a thickness about ½ of the slack space, dropped the rudder slightly and rolled the O ring onto the bearing near the top. Reinstalled the rudder. Took a bit to work the rudder back in, but the O ring did fill the space and eliminated the slack. Did this ~ 15 years ago and it still is tight. I think the idea came from this list way back when.
This may or may not work for your situation.

A cursory inspection does not show any adjustment or easy bearing replacement. All bolts are tight. There is some slack, maybe 1/8" when testing the tiller by moving back and forth at the dock. Has anyone else experienced this? Is there a known easy solution short of replacement? Should I be concerned. This seems to have gotten worse over the years.
