No one has been able to figure that one out Brad. Why don't
you post that question to Mike Eaton on his forum and see if
he can be more specific about it, maybe even steer you to some
documentation.
According to what I get from his statement, the grease
chemically reacts with 5160 alloy. His test is that heavy
trucks that leak steering gear fluid onto front springs cause
the springs to eventually fail. But.....I've not been able to
verify that from any other source. If that were true you would
think that one of the metallurgical sites would have discussed
that phenomenon at sometime.
And graphite would certainly reduce the friction but just like
grease, oil, Teflon or any other dust or loose fiber suspended
in a fluid, it wouldn't stay between the leafs for very long.
A least not where the leafs were in contact with each other
where they moved. That was the reasoning behind the wrapped
springs years ago, that is, the retention of the lubricant.
