I would suggest LPS-2 as superior to either WD-40 or Silicone spray in
this application. Silicone sprays usually contain very low amounts of
silicone, and are mostly just comprised of petroleum Distillates, as is
WD-40. LPS1 (low viscosity version that leaves a slippery dry film) and
LPS 2 are widely used by aircraft manufacturers, and others with more
serious requirements for lasting lubrication. Surprisingly, it is widely
available in Auto-parts and hardware stores. Even Walmart carries it!

Robert, If the 3 in 1 oil you used stops working, try spray silicone. It's
supposed to be the best lube for Delrin plastic. It's the same material as the
ball bearings in roller furlings and WD40 or silicone spray work best there
too. If it's a long term problem I would get a new bearing machined. It can't
be that expensive and others have replaced theirs. It would drive me nuts
listening to a squeek in a quiet anchorage as the rudder moves with waves.
