Your CJ7 is really 2 WD unless it has LSD (limited slip differentials) or

to take off again you never will in "4WD" or "2WD" with conventional
differentials.

Mine had locking hubs, which meant I had to get the f*ck out every
time I wanted to switch back and forth.

Conventional differentials turn the wheel with the least resistance, they're
useless in real slick going, even if you have 4WD.
