We had Alcan put the 5000# neverlubes on last month so not much experience with them (no problems so far). You can get the axles without the neverlube option. Per Lew, the bearing inserts (on the neverlubes) can be replaced down the road without replacing the axle if one does go bad. We full time so our weight is maxxed out at all times when disconnected from the TV. Peace of mind for us.
As David mentions...stay true to Lew's torque directions, and then some. I was still torquing at 1000+ miles.
Best of luck,
John
