Trim Tab Actuator

Has anyone rebuilt or replaced the Trim Tab Actuator? I have found that the free play in my trim tab system is more than desirable. I replaced the bushing at the tab and that helped but I still would like to tighten the play. After doing some initial research on parts and rebuild it appears this is a very expensive device to rebuild or replace. Replace looks like it is out of the question as I have not found any replacement available. There were some old references to the full replacement part # 1432004-1 which is superseded by -6. There was some references to this part at like $2500-3000.00 range. Ridiculous, now I have been checking for replacement parts and have not been able to come up with the screw assembly - actuator #1432004-4. I can only imagine the price on this critter when the other end of this system, the sprocket is $312.00 and the internal thread screw is $200.00.

The other parts are basic bushings and seals and do not appear to be a problem but my concern is will only replacing the bushings and seals fix the play or do I really need the threaded parts? As I look at it the play is in the threaded parts and the rod end bearing. Also there are two connector tabs that connect the rod end of the actuator to the bell crank that look as though they were made from a beer can. These also have some play but I can't believe these cheap little items are in the system.

Am I just overreacting? Making a mountain out of a molehill? What were the tolerances when it left the factory? I have close to 1/2 inch of play up to down on the tab.
