Last year i replaced both front hubs and reduction gears, one 2 months before the other. I am not sure if it is because of very hard loader work, or because the shaft seals failed first: I replaced both hubs with a handfull of filings in it, the shaft ate into the axle stub, driveshaft bearings were totally gone. The 25cm diameter ball bearings for the wheels itself had dents in the bearing cages from all the debris, and the hub input driveshaft could wander an inch when going forward/reverse, untill it ran so misaligned that the teeth of the gears collided.

Oh, if anyone ever replaces such a hub: change the oil and flush all the filings after 5 operating hours, and after 25 again: the replacement gears were rough milled, not ground, which produced enough filings to bust the needle bearings of the driveshaft again. I noticed that on time, now its running fine.
