Lynch HUMMER Pre-owned HUMMER Headquarters. - the factory materials say two things about the helicals: quieter and less rocking (lash) when stopping.
12k hubs are no stronger than 10k hubs - it's the half shafts that are stronger in the 12k setup ( and brakes ). The geared hub is not a weak point that needed addressing by AMG. Other than seals, and the spindle nut (not changed for the Alpha) they just don't break - even when you loose most of the gear oil from one.
Cheers,
Clarke
Straight-cut gears are superior to helical in strength - which is why racing transmissions use them.
