Once you're stuck, the open differentials show their true colors. Because you will never get out.

But as long as you have some momentum they aren't terrible.

I'm pretty sure I have the select trac transmission on my zj. It says in my owners manual that when I put it in 4WD low it locks the wheels so they all go the same speed. So even if it is in that mode it's still going to slip?

select trac refers to your Transfer case. If you have open differentials, yes you will still "slip" even in 4low. Your transfer case distributes power to the front and rear axles. Your differentials distribute power to your wheels. If you have an open differential in an axle, you essentially have 1 wheel driving the vehicle at any given time.

The tow package had rear lsd. Get your build sheet from jeep and it'll tell you what you have, they're amazingly fast to respond.

the locking in 4lo/4hi lockis refering to the fact that while in 4lo and 4hi lock the front and the rear axles must turn at the same speed. Its why you are not supposed to use it when in a full traction situation, going around turns, your front differential wheel speeds will differ from your rear differential speeds, and you will have drivetrain bind up. It can cause damage, but usually will not, unless you use it to often.

If you have Selec-Trac then you have the option of full time 4hi which leaves the t-case open allowing the front and rear diffs to spin at different speeds. Your 4wd drive lever should read 2wd, part-time, full-time, nuetral, 4-low.
2wd should be obvious, part-time is locked t-case (use in deep snow, mud, general off-road wheeling), full-time you can essentially use all year on any surface without doing damage to your driveline, 4-low is locked t-case and low range.
