Larry,
The Gary Hall kit (smaller OD stainless wire in a Teflon tube) will
prevent further wear of the hinge by eliminating the metal to metal
contact. If, however, the holes are worn already you may still have a
lot of slop in the hinge. You may need to replace the hinge. Measure
the hole ID to see what you have. New MS20001-2 through -6 and -9
through -12 has a hole diameter of .093 +.005/-.000. The hinge pin is
.089 +/-.001. Every hinge I have measured so far has come out on the
large side when new: .096-.097. That is a lot of play right out the
box. Another option is to use .094 stainless wire(standard size) or
stainless 3/32 welding wire(.09375). You may need to ream the new hinge
material to clean up the ID (reamers available in .0005" increments from
McMaster, .0955 works well).

My aileron hinges are getting a little loose. I seem to recall
discussions of oversize pins and / or teflon coated pin material. The
ACS catalog only lists .089 pin material which I am assuming is the
standard size pin. I suspect a little oversize would be appropriate.
