Ok you can color me disinterested now, there's no way I'd want to forgo maintenance to the front axle and let it go even 5 years, let alone 30. As has been pointed out multiple times before most of us actually like popping off the spindles every couple of years. I'll probably never run Amsoil for the same reason, I just like changing the oil too much to give that up...
