How does the Trunnion work?

[Kendall Larsen <mailkendall@sbcglobal.net>]

Hi List,

I don't really get what's going on with the trunnion... Is there some sort of
bearing in there that I don't see in the catalogs? I'm in the middle of
replacing the front bushings on my TR6, and I have a new trunnion to install,
but it seems to me like the old one is just fine. Any suggestions on how to
check if it is worn out? Never visited the front suspension of my car before so
the trunnion is a bit mysterious to me right now.

Thanks for any input!
