Good tip! Also if you do it on a very warm or hot day that grease will flow easier, and if the hub is hot that will help too.. Lay out a tube of grease on the asphalt in the hot Texas sun in August and it is almost liquid after an hour or so.

I did use an air powered grease gun on my last camper with EZ lube hubs and always had grease all over my wheels after a trip. I did not have any from the rear seals. Maybe it was the air gun that caused the problem. I don't want to make the same mistake on the new Flagstaff so I will get a manual gun. I asked how much grease to pump in at the PDI and he really couldn't give me an answer. What is the guideline? I like to be generous with grease and I thought overgreasing is what caused grease to get on the wheels.

I believe that the EZ lube hubs are drilled so the grease goes in
the end of the spindle and comes out behind the rear bearing between the rear bearing and the seal.
Then it moves outward thru the rear bearing and then
thru the hub and finally thru the outer bearing
and appears as excess oozing out around
the outer bearing washer and nut.
This is a pretty good design as it forces out most of the
air and more or less completely fills the hub and bearings.

If done correctly and SLOWLY it should not blow out the rear grease
seal as the excess is vented out the end around the grease
fitting. Stiff cold grease or grease shot from an air powered grease
gun can be forced out the seal as it cannot pass thru
both bearings and out the front end fast enough.

In my case, after I disassembled a couple wheels I discovered
that my spindles are drilled and tapped for this grease fitting in
the end but it was not installed.
They (Forest River) saved all of 2 or 3 bucks by short changing
my trailer.
All it needs is 4- 1/4 28 grease fittings and 4 grease caps with
the removable rubber center. These can be bought for a few
bucks at etrailer.com

I'll put in a temporary grease fitting and fill each hub thru the end of the spindle.
Once grease is all the way thru the hub and coming out the front
bearing, I'll re-install my bearing buddy caps and be done
with it.

Well yeah, there is still that little chore of adjusting
all 4 brakes

Al-Ko "owners manual" says to use lithium #2 grease.
This should work for most axles.

I posted this question earlier, so I thought I would tag it on the previous post. Does the color of the grease indicate anything special ??

Not that I know of.
Different makers use color dyes to show their grease.
Both my last 2 trailers which had different brand axles said
to use
Lithium complex #2 grease.
I have 2 different brands and one is sorta red and the
other is sorta blue.
They all wind up kinda black after a few thousand miles!

I found this on the Open Roads forum:
From the Al co site:

produced by a reputable manufacturer. The soap type should be lithium
complex or equivalent. Use NLGI Grade 2 product
with a minimum dropping point of 440o F.

Dexter is a little more specific:

I found the same thing the other day when i pulled the wheel on my 28a+ as I also found the castle nut to be really loose the keeper is there but man too loose for my liking I wiggled the back wheel and found it wobbly I know what i am doing this weekend.My spindle is also tapped but no fitting is it good to go to just add a fitting if so I will.I also thought the same kinnda cop out on forest rivers or lipperts part for .25 grease fittings
