Dexter EZ-lube

Check out this EZ lube video from Dexter. You are SUPPOSED to pump until all the old grease is pushed forward and out, and the new grease starts coming through. These are NOT "Bearing Buddies", they are a system designed for dry (not boat) trailers.

That looks like a good setup.

Many have reported grease being pushed past the seal and into the brake assembly with this system. I have no way of knowing if they followed the procedure shown or just pumped grease in.

I have this on my Cruiser and have always rotated the wheel while injecting the grease but just enough to see grease starting to come out of the front bearing, not a "complete repack" as shown in the video.

The one downside, even if the seal doesn't leak, is the inability to inspect the bearings and races, however I am of the school of thinking that I don't annually inspect the bearings on my truck so why is it necessary on the trailer.

Knock on wood, I've had no issue to date.

The trouble with your method, of course, is that the front bearing always gets the "used" grease that was in the rear bearing. I like their system. As to why we do this often, when cars and trucks don't; I believe the answer is tire size, and thus, circumference. Not so much really, on RVs, where the tires compare to a small car, but look at those little wheels associated with regular trailers, like you would buy at Harbor Freight or Lowes. Those little doughnuts have to spin probably 3:1 versus your truck tires to cover the same distance. The onus then, is on the bearings.

Does the Lippert axles have EZ Lube or does Lippert use SuperLube hubs??

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!

Great info Marty. I went out to my camper to check, but I couldn't see what ID is on the rubber plugs or axles. But after checking out both videos and diagrams, I see that both are really similar in design. I like new tech also and will go with the Super Lube until I pull off the drums next year to inspect brakes.

A few notes about my experience: It took TWENTY or so pumps of a full-sized grease gun before I saw ANY grease coming out the front. (Yes, I was worried that I was greasing my brakes, as the nay-sayers warn). But once grease started coming through, it was an equal amount per pump. Nothing came out of the brake drum. This tells me the originals were hand-packed, and nothing was in the Super Lube cavity in between.

I used grease designed for disc brake hubs because it has a higher drop point. I used Valvoline for Euro-Chevy-GM. They had similar but different for Ford. I did not use synthetic.
