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,
