Its pretty much the same as any other bearing pack Lonnie.
The best way to get a seal for it is to look at the numbers on the seal. It will usually have a number somewhere on it and that will tell you what seal to get from the store. Make sure you get what I call double contact seals. They are stronger than the single seals. The doubles have a spring inside them and contact the spindle in two places and are stronger.
I just packed my bearings a few weeks ago and researched alot online about how to do it fora Travel trailer and everywhere said the same thing, just pack them like any other bearing.
On the easy lube it is hard to get the cotter pins out and get them back in. Use new pins everytime though. What I did was put a small bend in the cotter pin before I put it in to help it along the curve of the hole.
Make sure to clean out the old grease out of the easy lube ports in the spindle. I did this by just attaching the grease gun to the grease fitting and pumping grease (while it is all apart) through it until I seen clean grease coming out the area where the inside bearing sits.
You may want to get a Lisle Handy Packer, they work great for repacking the bearings. easy and very clean to use.
Also make sure to "set the bearing" when your reassemble the whole thing. What you do is, put everything together, then while turning the drum tighten the castle nut until about 40-50 ftlbs ( I just kind of did my by feel I turnedthe nut until I couldnt turn it no more with a large wrench)then spin it a few times to set the bearings. Then dont spin the hub anymore and loosen the nut then put it finger tight and then put your cotter pin in, (without turning the drum again) once together it will be all set to go, and you can spin it as much as you want now!

.
Also check them for burnt or kind of blued races. Two of mine were blued so I replaced the bearings and races on all the wheels with new Timken bearings and races (the bearings used by Crossroads were made in Slovakia and I wanted American made bearings). Autozone has a set of race tools that you can borrow from them that you use to seat the races, and it works great.
