Are you talking between the 2 gears? If so you need to raise the rudder
with shims. The rest of the stuff that moves above the gears is what wears out and you need to do what you can to tighten things up. However what really is important, is to keep the rotation of the rudder
shaft as free as possible. This is what hurts downwind performance. In light air, the wind vane
doesn't have enough power to overcome the friction of the rudder shaft. You should be able to grab the rudder and rotate it as easy as can be.
