As technology in automobiles has advanced, so has the maintenance requirements for components. Wheel bearings on most cars/trucks these days are sealed bearings, typically "ignored" until they give problems. Those few vehicles with "non-sealed bearings" (Fords) require repacking every 60K miles.
Trailers do not share this "advanced technology" and are "old school roller/taper bearings" They require much more frequent maintenance. If you go to this website, you can view a 1960 Ford Falcon Owner's Manual:
https://www.manualslib.com/manual/10...page=46#manual On page 46 is a "maintenance requirement" to clean, repack and adjust the front wheel bearings every 12,000 miles. Trailers, for the most part, use the same type bearings that were on 1960 Falcons and require essentially the same maintenance requirements. Good, bad or ugly, that's just the way trailers roll..................
