The first thing I thought of is the torque of the stub shaft nut.
I think the $1200 is a lot of cash, for that you could buy Mopar ones and still have $ left over.
I like being able to unlock my hubs (CJ 30) untill it snows (and there unlocked while I'm driving), or I'm repacking the front wheel bearings (w/ new seals) just becouse I wanted to check them, or the worst is when I'm replacing them couse they get contaminated with H2O.
