I know this was an 11 year old post but i just came across it . I recently purchased the new rudder post bearing from the association and they are perfect , made well and it is an easy job like everyone says but I do recommend using some superlube synthetic grease to lightly coat them inside and out so you dont roll your o-rings on the shaft or the inside of the tube superlube wont hurt the o-rings mine was a tight fit in the tube, but after I removed the tillerhead and the retainer cap I discovered that I never had a rudder post bearing! it was M.I.A. but because the retainer cap was there it kept the slop down some and only slightly rubbed the shaft not bad , but I was lucky the P.Os never used the boat and it sat on the hard for so many years prior to them and maybe that was one of the reasons idk but what an improvement and the cap was missing a set screw also but as Ebb pointed out the retaner cap has to be set just rite for the set screws to bite.
