You ever try pressing on those wedding rings? They go with a fight, even when heated. Never mind taking them off.If the car has 9" axles and ends, the bearing is pressed onto the axle at the very outer end, and the bearing is retained in the housing by a plate with four screws. This makes it much less likely for the axle to come out if it breaks, because it is always going to break inboard of the bearing location. It can still come out because the press fit of the ring which holds the bearing on is not that much.
