Excellent question Mark! From what I can tell, the EZ Lube by Dexter, and the Super Lube, used by Lippert, function identically. Grease goes into zerk, through tube to back bearing, forward through cavity, through front bearing, and out. Now a word about what OUR owner's manuals say:
Lippert: Goes on at great length about need to hand-pack bearings every 12,000 miles. Says nothing about Super Lube, except in the picture breakouts that follow, they show every wheel with and without Super Lube fittings. In other words, they acknowledge they use and install them, but say nothing about what to do with them.
Crossroads: First paragraph says to take hubs, bearings, and spindle nut off and pack by hand every 6,000 miles. Para 2 talks about type of grease. Then:
Para 3 is titled "Super Lube" (quote) If the Recreational Vehicle is equipped with Super Lube, there is no need to lift the RV prior to greasing the axles. To grease follow these simple steps:
1. Remove the rubber plug from the grease cap
2. Insert grease gun on the grease zerk
3. Pump until new grease begins to appear. (my note; they said NEW grease)
4. Replace rubber plug.
The next paragraph says "hubs and components still need to be inspected and maintained per the manufacturer's (my note: Lippert's) guidelines.
So Crossroads doesn't even say lift and spin, but do it every 6,000 miles.
So here's what I will do: Once a year (approx. 4,000 miles if I'm lucky), I'll lift, spin, and pump new grease until the new grease comes through in the front. While lifted, I can pull, twist, spin, shake, and listen for anything not perfect in the wheel bearings. When I take it in for new tires (every 4 years?) I'll have them pull and inspect the hubs/bearings.
If this doesn't work, or gets me in trouble, I'll let you all know! I'm going with the modern technology, and I'm not going to hand-pack!
