Now that takes me back to my youth.

Larry, 

My only point was that there are more forces than just right to left,
vibration being one. Hence the need for rag joints on older cars steering. I
wasn't meaning you were wrong, I apologize for not being more descriptive.

Larry, 

They would only have a left-right if the shafts you're connecting are in
line with each other, which there weren't. 
=========================== 

I have no classes in physics or mechanical engineering showing on any of my
transcripts, so my ability to properly analyze and then describe such
matters is, I must admit, 
challenged at best. 

>From Steve’s reply, I infer he is pointing out my “left-right” descriptive
term was lacking, incomplete, or wrong. Perhaps if I had included ‘swivel',
or ‘articulated', or 
some other term, Steve would have penned a kinder ‘review' of my post? 

I’m not sure if he was trying to state the forces on u-joints used in a
steering column and the ZF shift linkage (to include the push me-pull me
forces) are in fact the same, and thus his successful experience with a
steering column application should be thus expected to transfer to a
successful shift linkage application, or if he is just pointing out my error
in using the “left-right” terminology. 

Sadly, no clarifying explanation was delivered along with the critique. 

I still fail to see how a steering column u-joint’s actions (however they
are properly described), where both ends of the shaft are in permanently
stable positions, even begins to see the same push me-pull me forces seen by
the solid (no slip joints) ZF shift rod in its forward and rearward
movements during gear changes. 

Slip-joint steering columns. Solid shift linkage. 

Apples. Oranges. 

My 2¢ 

Larry - educational critiques wholeheartedly solicited ;-)
