If it did i would grease them once a year or every 10,000 miles with this. Mobile 1
You nee to lift each wheel and spin it while you are injecting the grease.

I lube mine before my long spring and fall trips, with a couple of squirts of approved grease. As mentioned spin the tires while lubing, that means lifting the axle.

If you put your axle underwater (IE boat trailer) then use the EZ Lube port. The idea is to displace all the air in the hub so that when you dip the axle underwater...there is no air pocket to contract and suck in water. You really don't need to do this with an RV axle.
I recommend ordering new grease seals, cotter pins...and preferably having spare sets of Bearing cones/races just in case you find a worn bearing...(scored, pitted, or scorched)
Pull you hubs, remove the bearings, clean them completely...and inspect them. You will have to destroy the grease seal in order to remove the rear bearing. Replace the worn bearing...repack the bearing...replace the rear grease seal...reinstall you hub...and go another 10,000 miles.
To me...the whole idea behind the EZ-Lube is to routinely push enough grease thru the hub to see if any emulsion has formed (grease-water mixture)...indicating your hubs leaked water when you launched your boat. Great for that application. Just a unwarranted risk for the RV axle. If you grease them...and grease leaks past the rear seal...the grease can get all over your brake assemblys...and the only way you can see this is to remove the hubs to inspect --- why bother???
But that's just me.
Run your hubs...touch them from time to time to see if they're getting hot...and repack/inspect them on a regular basis (1 yr/10,000 miles whichever comes first) or so...

Sort of hijacking the OP, but why are the bearings in trailers so short lived. The bearings on my car & truck certainly aren't pulled, inspected, and relubed once a year or 10K miles.
Why are TT bearings? Lesser quality? Poor spindles on the axles?

Because it's just a CYA thing for the manufacturers. In reallity it just isn't needed. I used to go through them every year but when I got this last TT I realized that i had been wasting my time. I finally went through mine after about 40K miles and 7 years. It was a complete waste of time. They were still just like new and could have gone many more miles.
A person should check they're brakes and adjust them every year but if the bearings are done right, they probably only need to be gone through when the brakes are replaced.

I've asked the same question, haven't really heard any good answer. I suppose for the folks that use the trailer once each year for a 2 week vacation then let it sit for 50weeks, annual packing may be needed since grease more water/rust etc. may get on the spindles etc. But for myself, our trailer rarely sits more than a month between uses. gets 10K miles/year. Seems like if the bearings are quality and packed well, they should go 5 years or more without needing service.
And for every person I know that does the once/year routine, I know probably 10 that don't and go 5-10 years between service. Neither group has had any bearing failures.
Maybe a way for dealers to get some extra $$$ from service???
I personally would not use them. I would pull the wheels, check the brakes, and then pull the bearings and regrease by hand. I had an outfit that was supposed to do it by hand but instead, used the easy grease nipples and ended up getting the grease all over my brakes. What a mess. That was on my 5er. After that I always did my own. Macktee
