So it looks like I have command-trac, the shifter is set up like meh_kick has it. SO which is better, or is it just a matter-of-opinion?

Select-trac has full time all the way up

do you mean in order on the 4wd shift lever?

'cuz mine goes in this order:

2
4 PT
4 FT
N
4 LO

uh for future reference the "extra" shifter is the transfer case position lever. All it means is that you have 4wd. An command track is better offroad due to stonger case. select track is better on road due to the aboilty to use awd

I would say both systems are equally capable off-road, but Selec-Trac just gives the driver the added convenience and security of an AWD mode.

think about it too....your KJ will do fine on the roads in 2WD...do you really need Fulltime 4WD for the highway? for your suburban streets or the parking lot? No not really and if you find yourself in a storm or some slop or snow with your command trac, throw it into 4WD without worry...just don't do it on dry pavement....but then again, why anyone would need fulltime 4WD on dry pavement is beyond me, maybe there's some reason...2WD handles dry pavement just fine. If you are in a dirt road situation (again dry) you can use your 4WD on that too...is all about the 4 tires turning the same...without selectrac (which enables the 4 tires to compensate and turn at different rates while cornering on dry pavement) making a turn on dry pavement, your tires can bind like everyone mentioned....on the slippery stuff, they can adjust with the slip of the terrain.

Can anyone fill me in on what the benefit is of having fulltime 4WD on DRY PAVEMENT? What's the purpose of being even grippier on dry pavement? I guess the one thing I can think of is maybe towing on a steep grade, but what else am I overlooking??

So, in Part Time 4WD mode, do all four wheels drive at all times, or does the 4WD kick in only when slippage is recognized, such as ice or snow?

I am new to the Part and Full time 4WD too. Tell me if this is right?? Last week, we had our first big snow storm. I shifted the KJ into Full Time to drive to work, on roads snow covered and drifting. After most of the storm was over and roads cleaned up, but still slushy, and ice spots on the rural highway, I shifted to Part Time when driving outside of the town limits, where the roads got a bit spotty.

What is right in these conditions?? Should I have been in Part Time while storming too or Full Time for both, or just what I had done?? This Part and Full time stuff has confused the crap out of me lately.
