I have yet to do this myself. A bit scary.

Don't know how you can tell if you have a blown/defective seal until your brakes go bad. Maybe Napa doesn't stock US made seals?

FWIW, I'm an ASA certified Master Mechanic and have taught brakes and front end at a local tech school before retiring. Just using common sense will make it obvious to anyone that the only grease that is "working" is the grease packed within the bearing rollers and races. A little extra grease should be placed on the inside edges of the inner and outer bearings to be picked up as needed while the trailer is rolling down the road. The inside of the hub should remain grease free to allow for expansion and heat dissipation. That's the way they came from Dexter, isn't it? That's why it takes a tube per axle. You're filling up the hub Dexter left empty, as they should.
I wonder how many users of the EZ Lube axles who thought they had forced grease past their seals were actually victims of heat expanding the grease with no place for it to go.
Just my 2 cents.

If the grease expanse it will come out the front of the hub the same as it does when you put grease in the zerk.

I was asking a few questions about the E-Z Lube axles last time I had our Roo at the dealer. The mechanic there told me their recommendation to everybody who had E-Z Lube hubs was to not use the grease fittings. This surprised me, but the reason was that they get a lot of seal failures in for repair after owners have greased them which is an expensive job. Its not everyone that has an issue, but they see enough of them that they recommend just treating them like traditional bearings. Inspect annually, re-pack as needed. It also eliminates the issues of incompatible grease being added and the mess of completely filling the hub.

Something to consider, I guess. But it certainly surprised me when the tech's opinion was that the E-Z lube's create enough issues that worth considering not using the grease fittings.

You run with the grease cap off?

There is a rubber plug in the end , no grease cap on the ez-lube like I had on my non ex-lube axle.

I agree with awillis3 You should never pack the bearing Assembly full of grease. I have run into many failed bearings over the past many year due to too much grease. It traps the heat in the bearing as it is an insulator and will not let the heat transfer to the wheel hub. This will overheat the bearing and will cause the bearing to fail.

hope this helps Tim

Greased my bearings last summer on my unit. Went on line and found several real good videos on how to do it. Replaced old grease with a different cooler grease so I could tell when most of it was out. As I greased each wheel I spun the tire. Had a container along with a stick to get rid of the old grease. Took some time but felt it went real well.

Well, when I get the rest of my new Timken bearings and SKF seals, I will repack them and fill the cavities with Lucas Red "N" Tacky via the grease fitting on the end of the axle like I have for the last 9 years. Haven't had a problem yet, but who knows???

Got the 4 outer brgs today. Guess where they were made?
