Dennis,
I think your problem is accelerated by UV degradation. Delrin isn't all
that good in UV exposure. I would suggest using bearing grade PEEK but
that is a lot of overkill. You may gain some advantage by making a
sunbrella cover for it (or just replace it every 7 years).
I never ended up replacing the one in Corsair. It just needed a little
McLube every now and then so that it didn't squeak.

OK, I just replaced Touche's upper rudder bearing for the third time
in 20 years. It gets a little sloppy with use. It's a simple Delrin
disc. I had a few made by a plastics machine shop years ago so it's a
simple task to replace it.
I've been thinking about beefing up this bearing for years. So, if
interested, please read this document and tell me if I'm nuts or if
you have any better ideas.
