E-Z lube axles

Like other say, use a manual grease gun and spin the wheel while pumping in the grease. First time took 3 grease cartridges and the following years only took as much grease as you want to inject. Just take your time and only pump if the grease is coming out. Spin the wheel to help with the process. Air operated grease guns will blow out the seal.

Have them on my Montana but will not use them. I pull wheels off and inspect brakes and bearings every spring then repack at that time. Waste of grease filling up the void between the axel and center of the brake drum to get grease to the front bearings.

I used them on my 5er. No problems with seals or brakes.
I followed Dexter instructions carefully. Pumped slowly with a manual hand grease gun, continuously turning the wheel while pumping to ensure the grease gets thru the inner bearing with minimal pressure, and pumping until I saw new grease coming out the front. It did take a lot of grease.
Anyone saw me probably wondered what the heck I was doing sitting on a box, one leg up in the air turning the wheel with my foot, while I used two hands to pump the manual grease gun.

I've used the E-Z Lubes on 4 trailers. Never had to replace bearings or brakes on any of them. They work for me.

I used it ONCE. Had to replace my brake shoes later. Even Dexter techs. don't recommend using it.

My Rockwood came with E-Z Lube axles (not to be confused with Bearing Buddies).
Has anyone actually used this feature?
(Alert: I'm a retired ASE certified Master Technician. Please, there is no need to explain blowing out hub seals, the wonders of inspecting and hand packing bearings, the opportunity to look at the brakes, etc.)

I have the EZ lube bearings. It is interesting that Dexter recommends an annual bearing check, cleaning and repack even with EZ lube bearings. So, I guess I don't really get the advantage of the bearings for fifth wheels and travel trailers. Once, I used the EZ lube grease nipple to add more grease to the bearing. It takes a lot of grease and gets very messy later when checking the races and bearings.

please do a search, this has been written about Ad nauseam.

I had problems, like many other doing this. And yes I did it properly.

IF you want to take a chance on messing up your brakes...go far it.

I have them on my boat (21ft) trailer and RV and have had them on many other trailers I owned over the years. They work as advertised. Never use an airpowered grease gun to add grease. I jack up the axel and rotate tire as I pump in fresh grease. Never had a bearing failure even on the boat trailer.

I have them on my Crossroads Seville as well as my utility trailer. Work as advertised for me.
