HI Nancy G.
I did not pick it up in your note, but what Hematite and Sunline Fan are describing is the EZ lube feature that some axles have. Do you know if your camper has this feature?
If it does not then there is no topping off, you have to pull the wheel and brake drum off and manually hand pack the bearings.
The EZ lube system looks like this. There is a little rubber cap on the ends of the axle if you have this normally.
You can see here how the grease flows through the system. And I agree to jack up the wheel and pump slow while slowly rotating the wheel. Dexter tells to do this and Alko says you do not have to. For my camper, if I ever use that feature it will be when the wheel is spinning. While I have this feature, I do the hand repack. I added the grease fitting setup in case of real long trips out west I could add/top off some if I needed to. Even if you use this greasing feature the brakes need to be checked and that means the drum has to come off.
If you have the manual hubs, see this post for a pic-o-gram of a step by step bearing and brake setting on my prior T2499. That is for a leaf spring axle setup, however even the torsion axle greasing is the same.

If you look here on the forum under our "files" tab at the top, there is a section for axles and running gear. There are both the manuals for Dexter and Alko axles. There is also a Dexter Grease chart that lists all the brands and types that can be used in your camper regardless if it is a Dexter, Lippert or Alko axle.
Here is the files tab hot link Files Tab
Hope this helps and good luck
