During service, you remove the plug, Install a fitting, grease and then re-install the plug.

Absolutely no hole for grease. I checked. So itís not cross drilled either. Because itís stronger without the holes. They fail before running dry apparently.

My John Deere 4 wheel drive tractor has two drive shafts. The one drive shaft is just about totally hidden and has greasable Zerks, one per U-Joint. The other shaft is completely accessible and it has sealed U-Joints! Go figure!

It just goes to prove, you really need top know your equipment and not just rely on "Bubba", the guy the "certified mechanic" sends out there to do the oil changes and grease jobs!!!

I have seen u-joints with a grease zerk on a cup rather than having the cross drilled. But they are rare. Made for extreme duty situations. I can't even remember if there were 4 or ? how many. It might have been on an old Hayes logging truck that a customer traded in for a new Hayes Clipper logging truck. The old one had a Rolls Royce engine. That was back in 1971, so getting a little foggy.
