Clayton,  

likely you do not have a loose shaft.  Typically the Alberg rudder shafts have four 1/4" bronze rods stuck through the shaft and and embedded longitudinally into the rudder blade,,, to prevent any twisting motion you described.  if the lower pin and rudder shoe is worn, and it likely is, you won't be able to feel any appreciable play just be hand forcing the rudder.  only time you will feel anything is when sailing under fairly high side load, reaching or running in my case when I discovered my lower rudder pin was worn and elongated.  

In my case, I machined out the lower socket to accommodate a 
 5/8" diameter pin, and replaced the shaft then turned the end to 5/8" to fit into the shoe.    so now lots of strength and larger bearing surface.  plenty of A30  owners have reported successfully drilling out the pin and replacing the old pin with a 1/2" silicon bolt tapped and screwed up into the bottom of rudder shaft,  then cut off to produce a smooth shank to fit into the lower shoe.    this works also, however, there is some risk of dissimilar bronze in the two materials- shaft and bolt, so is worth inspecting each year at haul out.

Cheers
