But isn't the difference here that the bearings on passenger vehicle axles are sealed, maintenance free (by design) bearings? Bearings on trailer axles are not designed to be "maintenance free" or sealed, and thus the grease needs to be maintained periodically... ? That was my understanding anyway...
