The hub assemblies don't use a green-style bearing (Edit, I'm considering this in reference to the old-style green bearings. No comment on the "new n' improved" ones). They're angular contact ball bearings. Using angular-contact balls instead of tapered rollers, they absorb thrust just like a Mopar 8 3/4; there's no diff in the middle and the end play is controlled via fixed spacer.
I won't dispute either point. After a quarter million miles on my neon, I failed one. I suspect the others will start growling on the way to work this morning.
Of course, there's more maintenance involved, but factory 8 3/4 bearings will last as long too. Green bearings (Gen 1? Gen 2? beats me) maybe not so much.
