The front hubs have a open hollow center that is big enough to stick you hand in and it reaches all the way to the rotor. It appears as though after taking off the lug nuts and then the hub nuts the rotor would just pull right off after taking off the caliper and pad assembly. I think if there is a bearing it is something at the rear of the spinal and not part of the hub or if it is it certainly is not anything you can just remove like the old cotter pinned bearings. I know what you mean. I had a 56 chevy for many years and they always had to be re-packed. Most of my cars over the years had packable bearings.
Thanks
