Some use it to replace grease on travel trailers.

Dexter (and other axle mfrs) REALLY over-blow the maintenance issue to scare people on these axles. As Floyd stated: simply a CYA issue! They admitted as much (not in those words) to me.
Hi Darrel . Question for you I have about 8000 mi on my trailer . Trailer is Nov. 2013 . I have been acquiring what I need to do my bearings . Good idea or wait a little . I use to do my 1964 Chevy back in the day so I have done this before . I am just confused on when to do this . Pat

Hopefully all that grease was just filling the hub before it could come out the end

Since the first two cartridges used on wheel #1 had a great deal of grease in each one, I am going to assume there was an air pocket in the middle or so of each tube. When it happens again, I will try pulling and pushing the plunger a couple of times and see if that works, as Floyd suggested.

I did check behind each wheel to see if any grease came out and I do not see any. I will do short hundred mile trips soon and that should tell me if the brakes are greased up, which I do not think they are.

Thanks to all that have replied.

Hey Pat. As a Disclaimer, stating what I do is by NO means a suggestion to others on how they should maintain their trailers. If in doubt, go by the manufacturer's recommendation.

But for me? I've been around mechanics (am a former machinist) ALL my life. Keep in mind, my Scamp 13' weighs only 1800lbs on a 2200 lb rated axle and I do NOT load it down traveling. When I'm not traveling, I keep my Scamp off the ground on jacks, spin the wheels regularly year-round. I take my Scamp out in the spring and pull for a min. 15-20 miles at apx 65 mph steady. I have an exit ramp on a 4-lane where I pull off....get out and check the temps. I do NOT use my trailer brakes when stopping to check the hubs as you WILL get a higher reading!! And this can throw you for a loop! I also check for "play" by placing my hands one on each side of the wheel and try to shake it back and forth. Vigilance is EVERYTHING on anything/any vehicle.

My hubs still run the same temps as when the Scamp was brand new in 2010 and 10000 miles ago from Scamp. I did adjust my brakes last year.

Again, this is just MY opinion and I dont recommend it for others. But do you pull the front wheels (or rear wheels on front wheel drive) vehicles and check the bearings every year regardless of the few or many miles you put on it?? That's basically what the axle makers are saying.

I'm not saying whether to grease through the EZ Lube regularly or not. Just dont know without thousands of miles of tests whether what is 100% right or wrong. Many feel to pull, clean, inspect, replace, repack their bearings EVERY year. I do not and will not unless I have a trailer that I KNOW is running borderline. If I have that trailer, I dont want it for long. Mine has built-in safety margins on both the axle and tires as you can see. My tires are rated at 1326 each. I have apx 900 at full load MAX!

Good luck and do you what you feel you should do.... I've seen/heard of some doing the maintenance job, and they get the bearings too tight going back together and REALLY have trouble. So, regardless..... KEEP A WATCH ON YOUR HUB TEMPS AT ALL TIMES!! I spot check mine at every fill-up.

It's bearing buddies which are designed for and work for boat trailers. A completely different technology.

But how can you tell if grease is travelling through the entire inner bearing. And it seems to me that you are pushing contaminated grease from the inner bearing through the outer bearing before clean grease arrives. How do you know the bearings are good? How about the seal?.How do you know the brakes and associated mechanism is in good shape? The last time I greased my bearings I found a wire had come loose just enough to make contact and insulation was worn. Finally it seems like when you do take things apart there will be one heck of a mess to clean up.

I had never greased bearings before I bought a trailer. I followed the instructions in the Dexter manual. It takes me an hour from start to finish to grease my bearings by hand, inspect the tires, and set the brakes. As some often say it's a maintenance issue. Raz
That would be more prosaic than poetic I'm sure!
Note that I use my EZ-Lube feature between brake servicing and have found the grease and bearings to be in excellent shape when I disassemble for brake service. The grease is not prone to contamination in this application and even condensation is discouraged since there is no void to allow it. Of course all the grease is replaced when the bearings are repacked by hand at that time.
Trailer brakes can be checked and adjusted effectively without disassembly between servicing as well.
My Ranger (rear drive) got its first hand repack at 92000 miles and seven years when the brakes were serviced, it is now 15years old and the brakes and bearings are at least as good as new.
Perhaps it is a waste of a few cents worth of grease and it has certainly a waste of time to inspect too often. The peace of mind received may help find the right balance....
My Gramma used to say that it is bad policy to uproot radishes just to see how well they are growing.

Yeah, that and the folks that make the axle say so.

I disagree. From everything I've read about bearing buddies...they're basically useless....by not sufficiently getting grease to the rear bearing.

A Dexter engineer is the one that told me they developed the EZ-Lube for helping displace the water in boat axles. So you need to disagree with them. Look up the "E-Z LUBE" article on their site. Quote: "E-Z Lube is designed to allow for immersion in water."

I'm confused. Are you comparing Bearing Buddies to the EZ-Lube? The Devil is in the Details Darrel, not just one sentence in a graphic or brochure.

This is a Bearing Buddy... and that's all they are.

Perhaps someone else will be able to confirm one way or another but I am not so sure that you would actually see the grease behind the wheel. May all be piled up in the hub around the brake assembly. If it was me I would take the 5 min. need to pull the wheel off and check it rather than waiting to drive down a steep hill to find I was wrong and have no brakes

Nope...not comparing. I've just heard that the bearing buddies will only sufficiently grease the FRONT bearing on an axle. The EZ-Lube is designed to grease the rear bearing FIRST then push the grease forward through the front bearing then out.

I was simply stating that Dexter said they designed the EZ Lube with boat trailers in mind to help displace water that can get in there with the boat trailer continually being submersed. Maybe BB's were designed for boat trailers...dunno...that's not my argument...but I certainly wouldnt trust them for greasing my axle bearings.

Edit: I think the confusion is where Floyd said Bearing Buddies are designed for Boat trailers.... All I was saying is that is what Dexter said that about their Ez Lube. Alot of manufacturers are using the "EZ Lube" design under a different name...and I believe someone's already mentioned that.

I put Bearing Buddies on my tent trailer ( I had them on a boat trailer too ). I can assure you that they liberally lube the bearings, and the wheels, and the tires, and anything in the vicinity.
Sold the trailer. Not my problem.

No problem... I spent a good part of my life disagreeing with engineers and fixing their screw-ups!
