2019 OR Propeller Shaft: No Zerks for DIY Lubrication?

If it only has one zerk on the front shaft, it might have had one u-joint replaced. Hard to say which one, as your model was in the phase-out period, IFAK.

 

Here is a good article on greaseable vs. non-greaseable joints.

“Bottom line on strength: The non-greaseable joint is slightly stronger than a greaseable joint. The exact number, how much stronger, is unknown and we do not believe it to be very significant.

Bottom line on wear life: A regularly greased greaseable joint will outlive a non-greaseable joint. But a non-greaseable joint will outlive a greaseable joint that does not get greased properly.”
