Here's a breakdown with drawings of one repair method by West Systems. I'll be trying this method in a couple of months.

Subject: Re: [Santana 22] Rudder bearings
Hi Erik,
Rudder play in the Santana 22 is a common thing. Depending on the severity of the play, it shouldn't affect performance. If it's bad, then it'll only get worse over time as the brass and/or bronze bearings you may have found in your later-model tuna will become more oval. Earlier models had no bearings but just the rudder tube. I have some play in mine as well (#561), but I have not taken the tiller head apart yet to determine if there are bearings in there.
I have not seen the bearings you're indicating, but if there are two (top and bottom of rudder tube), and they are not epoxied in (important!), the top should be able to be removed with an automotive gear puller, one that has a threaded center piece that you can fit a washer and nut onto the end. Make your own washer out of a steel plate about 1" wide (no wider than the rudder post) and long enough to span the rudder tube inside dimension, and a slot or hole in the center wide enough to accept the width of the puller shaft. Then, thread the nut onto the end. Use blocks stacked on the cockpit floor for the legs of the puller to push against.
Once the top bearing is out, you should be able to pound the lower bearing out from the top using a mallet and a length of wood (such as a closet hanger pole or broomstick end).
Various methods exist on how to remedy the situation. Replacing bearings is a different story. You may want to contact Schock and see if there are replacements (I didn't see any in their parts catalog, but a phone call might prove more valuable).
The method I think might work well is replacing your bearings with an epoxy bearing version that you create yourself by adding graphite powder to your epoxy mix. On the Santana 22 fleet website, under the "Articles" section, there is a link named "Maintenance Tip: Rudder "Play"" in which Mark Lowry discusses how to do this procedure. It's actually easier than it seems. I employed this method on another boat (not a Santana 22) and had results very similar to those that Mark discusses in his entry to that article. You can find more info on this type of thing by getting one of the West System Epoxy "how-to" books from Gougeon Brothers. They are usually about $10 at Svendsen's or West Marine. They are really good about education. Here are some how-to guides: http://www.westsystem.com/ss/use-guides/ . You're also bound to find info on how to do this at the Gougeon Brothers' Epoxyworks magazine, which is devoted to working with epoxy. Sniff around the online version here: http://www.epoxyworks.com/ .
Finally, you may want to talk to Steve at Seal's Spar and Rigging. He's got loads of experience with these boats. Contact page is here: http://www.sealsspars.com/contact.html
I hope the info helps.

Hi All,
I have a question to the fleet regarding rudder bearings. I recently dropped the rudder out on my S22 #454, as there is a large amount of play in the rudder. I was under the impression that Santana 22’s did not have any rudder bearings (other than a fiberglass tube). I found that my boat has bronze rudder bearings and they are quite worn. I have two questions:
1. Does anyone have any experience or good ideas on removing these bearings?
2. Are replacement bearings available anywhere?
Thanks in advance for your help.
