Better still, carry a bearing/drum assembly, as the failed bearing must be pressed out and new bearing must be pressed back in. The repair shop did not have a press sufficient to do the work, so I had to take the drum to a tire shop to have the work done. Trust me, if one of these bearings fail in the “middle of nowhere”, it becomes a major PITA, and you could be down for days. I would choose conventional bearings anyway, as my bearing failed after approx 20K km.
The Nev-R-Lube bearing design is not unique to Airstreams.
The bearing only can be replaced if the hub is not damaged beyond reuse.
As far as availability I bet any medium sized auto parts store has one on the shelf or avail overnight.
Special tools, either a shop press or a front wheel drive bearing tool set. These exist, maybe even a rental tool but it safely presses old bearing out and new one in, undamaged. I've done it on my VW front wheel hubs.
