Us4byrds, did you get your rudders sorted? Here are a couple of tips for you, learnt when I took my rudders out. Firstly, disconnect the bar connecting the two rudders; it may be that only one of them needs attention and you won't know which until they are seperated. There's quite a bit of information on this site which refers to removing the bushings from the rudder
housing. It's quite a big job but there is another way of doing it. After I had removed my rudder, I took a piece of of 2" metal pole, put a bolt right through the center of it and secured it through the tube using washers so the a bit stuck out one end. (See photo). I put some adhesive
sandpaper around the tube and connected it to a drill. I then used it to lightly sand the inner surface of the lower bushing which sits an inch up from the hull
. Don't sand it excessively or you will misshape it. I originally did this suspecting that it would be a temporary fix but several years on, the rudder still turns freely without wobble.
