I clean and inspect my bearings for any signs of damage. Helps to catch small problems before they turn into big issues that will have you stuck on the side of the road. That's hard to do when you're just blindly squirting grease into a hub. Bearings, even good quality ones, can develop issues for any number of reasons. Cleaning and inspecting is the best way to catch developing problems.
FYI, nobody does bearings on cars or trucks anymore because modern vehicles have either sealed hubs or wet axle bearings. Sealed hubs are sealed, not serviceable, and are often designed to last the life of the vehicle. If they fail, you just replace the entire unit. Wet axle bearings are constantly bathe in oil from the axles. Both are better than 50's technology used in trailers.
Sealed bearings are the same tapered roller bearings as non-sealed bearings, just not serviceable. They typically go 100k or so before replacement so that gives you an idea how far serviceable bearings will probably go if you never touch them. BTW, I have pressed a set of sealed bearings apart and there wasn't very much grease inside.
