Anybody ever cleaned and greased the stock hubs on the 86 Voyageur? They look like they might be cartridge bearing hubs, and I'm not sure I can get the dust cap/seal back on if I tried taking it off. I was able to regrease a pair for cartridge hubs before but they had another piece that goes on top of it so that was fine. But these don't seem to have that and I did try that once on a similar hub (without the extra piece) and I was never able to get the seal back on.
OTOH if they're not actually cartridge hubs, then maybe it will be okay.
