I figured it would be much easier to swap the entire hub assembly alongside a busy highway than to deal with swapping out bearings, dealing with re-packing grease, etc. I also kept a pair of nitrile gloves in my trailer kit for doing the greasy work.
I forgot to mention that if you do buy a spare hub assembly for your axle, fit it on the axle before you take it out. I bought one that was meant for my axle but the hub was slightly shorter than the one that came on it. The castle nut would run out of thread before it took up completely on the washer and bearing. I had to find another washer to make up the difference and those washers are hard to find.
