Bearing service on the A122

Has anyone done this yet. Our camper has already been all over the eastern united states, with about 30 days of camping this year. Our next trip will be down towards Lake Ontario ...and would like to lube these puppies up before our next trip.
I do know that these campers have easy lube hubs .. and have had experience with them on my previous campers ... but how the heck to you access the grease port? There is a plastic disk that seems to be premanently attached to the "mag hub" ... making me think that the entire wheel will have to be removed to service the bearings ... is this correct?

I believe the disk will pop out to reveal the grease zerk.
it may be tight

The cover over the zero does come off without removing the wheels.

yes, that hard plastic cover in the end of the decorative hub cover just pries out. the neoprene one on the end of the axle (bearing) dust cover pries out as well.
i didn't know the plastic one came off until i took the wheel off and saw the tabs on it. guess i figured it was fused in there.

This thread just saved me a bunch of moolah. I had an appointment this week to have the bearings repacked (didn't trust that the frame factory would have done a good job when it was made). When I saw this thread I checked my hubs, found the grease fitting, and mentally thanked you all...

These Lippert and Al-Ko manuals and tip sheets might help you with your bearings.

These manuals raise the question for me: what grease did the axles come with? I hope my user manual tells me! If not I'll have to remove and replace all the grease instead of what I'd hoped to do: just add some.

Page 21 in the alkobrochure.PDF. It's just regular lithium bearing grease, should be able to get it just about anywhere,

Per Al-Ko; they ship with Lithium Based NLGI #2 with a drop point over 450 degrees. Any Lithium based NGLI #2 grease with a DP over 450 will mix just fine if you have Al-Ko axles. The Lippert axles also use Lithium Complex NLGI #2 with a DP of 446 degrees.

If you have a different manufacturer you will need to call.

NOTE that you STILL have to pull the hubs and do a visual cleaning and repack every year. It is easy (but messy) to do if you are handy. Once you repack by hand, you should still fill the hubs with a HAND grease gun using the same grease.

Herk started a wonderful thread in "General tech and Repair" on bearing procedures etc. It has the detailed procedure, and the discussion on greases and where to find them. Lots of great stuff on the subject and I know it sure helped me out.

Thanks again Herk and happy reading 

Thanks guys. I'll look at that thread as soon as i get this iPad recharged. I worked in garages and service stations through high school so I think there'll be just the right info in that thread to set me on the right path.

Followed your advice and filled up my hubs the other day with Red 'N Tacky #2 (if memory serves me). It took 40(!) strokes of the grease gun before the grease already in the hub even began to squeeze out! I don't think the grease channels had anything in them at all. Is there an emoticon for "breathing a big sigh of relief?"

Same happened to me .... I doubt it very much that the factory is filling them with grease. When I repacked them, I simply changed all the bearings and the seals just to be on the safe side. The grease which came out looked very liquidy to me ....
