Rudder repair


I noticed that my Port Rudder shows some "slack"... I mean, i was cleaning my hulls and when cleaning the rudder i noticed that it was not as firm as usual attached to the shaft/hull. I believe i would need to change the (underwater) bearing/washer (i dont know what material is used for this ring..). This looks to be a fun project: how to take the rudder of the shaft? What material is used for this kind of bearing/washer?
The SB rudder is sturdy and no need for repair i think.
Somebody else had this problem as well.? How to handle.?

Thanks again for all yr valuable comments.
Best rgds

Re: Rudders - Steering

Just as a follow up I had my RH rudder lower bearing replaced recently.
Upon removal, which was rather difficult it appears that the aluminum outer bearing has corroded and seized the inner race in it.
The shaft has then turned on the inner race and worn to a large degree.
I think it would be a long while before it failed but the clunking noise is rather annoying when you are try to sleep at night.
I also noticed that there is some crevice corrosion starting on the shaft which I think will lead to shaft failure so I'm going to invest in some earthing leads.
This design is flawed and I will be looking at making up something like cat man do suggested as a permanent fix.
