When greasing the EZ-Lube you must jack up the wheel and give it a spin. Pump in grease VERY, VERY slowly while watching for the old grease to come back out around the nozzle. If the old grease is not coming back out at you then the inner seal is leaking! Buy a good quality double lipped seal. If the original poster never added any grease, then the trailer manufacturer probably hammered grease right by the inner seal by using an air-powered grease gun.
I agree that EZ-Lubes are better suited to boat trailers (that's where my experience is). Far superior to those @#$%^&* bearing buddies. Talk about your greasy brake linings. Bearing buddies put a constant pressure on the grease in the hub. That's an invitation for grease to leak by the inner seal. EZ-Lube just insures that the void is completely full of grease so that water isn't sucked into that void when backing a hot axle into cold water. It's that water (especially if it's salty) that eventually causes the bearing to fail.
Best of all: NeverLubes. That's what's on my Sunnybrook. I'm probably going on 30,000 plus miles or so with ZERO problems. I check them with a spin of the wheel when I adjust the brakes.

From what I understand, you should be careful to not force the grease in too quickly, otherwise you can blow the back seal out and grease then gets onto your brake pads....
Take it slooooow....
Ive filled mine twice so far without a problem....
When I had new Dexter axles with the EZ-Lube installed earlier this year, the mechanic at the trailer shop (not an RV dealer) was very adamant that you should never use a pneumatic pressure lube device.
Two things were stated. One is that the EZ-Lube must be kept completely packed with grease. That means all of the open space between the bearings must have grease in them. If not, when greasing you will only be pushing air around instead of moving grease in and out.
Second grease should only be added by a hand gun and done so very slowly until grease is just starting to ooze out from the outer bearing seal. Too much pressure and the grease will start to blow back out of the rear bearing seal and then contaminate the brake shoes.
