Vague question.

d30 front, d35 rear. Most likely 3.73 gears and most likely open in both.

Having two open difs is really like only having 2 wheel drive. The tire with the least amount of resistance will turn. (Ironically its usually the one not getting any traction at all that is spinning while the one on the ground does nothing) A limited slip usually contains a series of clutches that, with pressure expand and begin to grip and turn both wheels on the axle. Its not a locker but provides more traction than being open. Limited slip differentials provides better traction while still keeping the vehicle very streetable.

I know some D44's came w/ LSD. Not too sure what 35's came from the factory w LSD. I did have a D35 with limited slip though. So I know they are available. I have NEVER heard of a ZJ coming from the factory with LSD in the front axle.

Yes. I have an Aussie locker up front. With a 242 Tcase I barely notice it until I put it in 4 wheel drive. Look em up. Easy to install. Work effin great too.

I wouldn't go that far.

I wheel my D35 with 31s pretty hard and it's holding up just fine at 212,000. I will defend her!

Slightly holding the brake/applying the E-brake while trying to move is a good way to balance things out.
