bearing buddy type deally

Bearing Buddies are great for what they are designed for.........boat trailers. They keep a positive pressure on the hub to keep water out.

Unless you're doing something really weird with your TT there is no need for any of this stuff. Pack em, and give them a peek every 5 years or so and go camping.

E-Z lube is different than Bearing Buddies I believe E-Z lube has a hole that circumvents the seals. Bearing buddies do not. You push on an E-Z lube to hard and the grease falls harmlessly to the ground. You push on a bearing buddie too hard and you can blow out a seal. Just my experience at least.

Sorry but this not correct. I have seen EZ lubes leak and they have no special design by which to keep it off the brake pads - and that is exactly where it goes when it blows past the seals.
When you force grease in through the zerk, it flows through a hole in the middle of the axle and then back against the seal which redirects it forward and into the void of the hub. After it fills the hub the grease then moves forward and through the outer bearing.
This is why the seal fails. It must withstand a lot of continuous pressure as the grease moves through all this.
If a person just gives it a couple of squeezes and leaves it at that, you may not have done much. To get grease to the outside bearing you have to keep pumping until you see grease move around said outside bearing. Otherwise all your doing is getting a little grease on the inner bearing - at best. Or you may be just filing the hole in the axle.

You are correct Scott I was mistaken. I have an EZ load trailer with EZ load fittings on the axles but The EZ load trailer has channels machined into the axles which do not allow you to over grease the bearings.They call it Reliable Lube from EZ loader. When the Grease makes it way through the system it exits the back of the hub it would be impossible for the grease to flow down the back side of the hub into the brakes because the channel is cut so that it exits before it does any damage. But it does make a hell of a mess on the shop floor. The trailer is rated for 15000 lb and the axles are extremely heavy. I never looked at it till you posted so thanks I learned something.

Sounds like a better system for sure!

They are a gimmick to lure people into believing maint is easy. But they are no replacement for doing it right and are more likely to leak than not.
Even when one follows the directions to a tee you will have grease blow outs on at least some of your wheels. BTDT
You will notice that it's mostly the people here who have been doing this for a long time and have lots of experience are the ones to tell you not to use them.

For this application bearing buddies are not a good fit. They are intended for boat trailers they work fantastic for what they were made for. Then some guy decided maybe travel trailers could use them as well. I don't think they work very well on travel trailers. But for squeezing water out of your bearings they work fantastic. A couple of pumps and the water is pushed out of the needle bearings. On the other hand if you are going to submerge your travel trailer a lot they would be a great help. LOL>
