I don't know what year they stopped using them but the newer ones are sealed units and not greasable. I don't think they have been installing as stock for quite some time.
Most typical non-greasable joints (no zerck fitting) are inherently stronger units. You can have spicers with zerks installed but again not as strong as the sealed units.

The only grease fittings from the factory are on the U-joints for the front axle (if you have 4wd). One zerk on each, but they are tough to get at. If they stopped using them sometime after '05, I do not know, but my '05 has them, and none other.

My 01 7.3 4x4 SRW crew doesn't have fittings in the front u-uoints.im trying to decide whether or not to replace them .I'm doing some front end work and I'm thinking wile I'm in there! The universals dont seem bad now Ijust dont want to go back in, in 10 k! Question is Which ones ! I installed moog b-joints,think I'm going with national seals, but if the non greasable u-joints are stronger ,what would you use?
