Jim2002, not to worry too much. The first set of U-joints my locals installed had NO grease fittings!! I noticed it a few weeks later when I removed the DS for the new leaf spring replacement!

I marched back into that shop like a horny bull with his tail on fire! The shop said not to worry because they were greaseless joints, but I said "I want to see GREASE and grease fittings!" They replaced them of course.

There may in-fact be greaseless u-joints out there for our original DS (teflon?), but I haven't found anyone that can explain the differences or improvements.
