The thing is Bill, with the double-cardan joint installed, I can't even see
that zerk fitting (for the double-cardan joint ball). The skid plate that
holds up the xfer case is right there in the way, but even then the zerk
fitting is covered by the knuckle of the spider.

Does the double-cardan joint ball and spring assembly put pressure on the
spider to prevent wobbling?

Thanks for all your responses and advice too Bill. I really appreciate it.
Were you a mechanic in a previous life (maybe after you were in the army)?
What unit were you in when you were in the army?

Many time I have to rotate the zerk pointed and shot it blind, as
the angle is too tight pointed down.
Seems like that spring would give a little during operation, but it
doesn't, it's a must to give us enough room to pop bearing cap over the
lock cog on assembly.
I use the term universal joint, maybe star to further describe a
part of it, but spider is what we call the differential side gears
because of the angle their teeth are cut:

Yes, I was a mechanic in the Navy until Pearl Harbor, took me
twenty two days to die.
This life, I rebuilt my first carburetor at the age four, drove
twenty five dollars cars on twenty five cents tires, which of course
needed a lot of work to get to school. Caught the hot rod bug in high
school: http://www.----------.com/dragster.jpg Did twenty years as an
owner/operator Chevron Dealer: http://www.----------.com/chevron.jpg and
burned out, and thought Sony and Will's characters had a good job seeing
the U.S.of A. So I became an independent trucker driving a million miles
with two logs. Doing normal maintenance took all my spare time, giving
me a bunch more mechanic experience, but not much fun at ten cents an
hour: http://www.----------.com/kenworth.jpg
I was surveyor while in the ARMY '64 to '66, and tested all the
artillery divisions and the Honest John missile in Germany:
