The Jeep Liberty Limited 4x4 I'm picking up tomorrow doesn't have the Selec-Trac so I was hoping somebody could explain the difference. As far as I know, Selec-Trac just allows you to engage 4x4 at all times. Couldn't I just switch the selector on my Command-Trac Jeep to 4WD Lock and drive normally?

Command-Trac only has part-time 4wd (for slippery surfaces - not meant for dry surfaces) and 4Lo. It has no full-time option.

would you go as far as to say slect trac II is "better" it is an additional $445, but more is not always better. I guess from what I understand I can be driving do the road in winter and have 4wd auto and it will add more traction if needed and still be safe to run on a "dry surface".

It highly depends on your specific requirements, but between Selectrac II and Command Trac, the one specific question i'd ask, is are you at any time thinking you'll need on-road 4wd use?
If you can answer "yes" to that question, then pay the extra.

Honestly, i think more users need the selectrac ii then they sell.

Its too bad they took the 4 high lock option out, but on my WJ, and on cherokees past, i used 4 full probably 10 times more then i used 4 high lock

Well, yes and no. Driving on Los Angeles highways, I wouldn't need 4 wheel drive, but going around corners I'd imagine the Liberty handles better with power output to 4 wheels. I'm a fast driver -- like going around corners fast -- and I realize taking a Liberty around a corner quick isn't going to be quite as fun as a BMW, but it would be better with Selec-Trac I imagine, wouldn't it?

Also with Command-Trac, how long from the time you flip the switch from 2WD to 4WD, does it actually activate 4WD (immediately or a few seconds?) and do you have to be stopped in order to do it?

[madrabbitt]

are 08 liberties shipping with a switch activated 4x4 now?
i hope not.

and a command trac will shift nearly instantly, as long as you're in motion when you do it.

Great. Switches.
So much for positive lever activation.

[panthermark]

2WD - Most normal driving situations and when parking.
Full Time 4WD - Slippery conditions: Patchy ice, snow, moderate to heavy rain, dirt roads, ect....
Part Time 4WD - Extreme limited traction conditions: Off roading, heavy snow, deep mud, loose gravel, ect...

[yellocoyote]

i have the command-trac on my '02. i use the part time 4wd only in offroad situations, or times of fresh or deep snow, like stated above. once i reach dry pavement, i put it back into 2wd.

i don't like the 'switches' on the KK's... doesn't seem right.

Another question:

What's the difference between 4WD Lock and 4WD Low? In what kind of situations would I want to use 4WD Lock and what situations for 4WD Low?

And at what max speed can you drive with 4WD Lock active?

Get your owners manual out and read it over carefully. It explains eveything. Also on the jeep.com website there is an owners section and a section explaining all the different systems.

Which 4wd system did you get? There are 2 different ones for the KK.

Congrats on the new jeep.

First of all, full-time 4wd isn't going to overcome the laws of physics. If you like to take corners "fast" in your Liberty, you'll soon find yourself with the painted-side down-- 4wd or not.

Secondly, on any vehicle that has an option to select different drive modes, engaging more wheels will result in less power getting to the ground due to the greater drivetrain loss. If you want more power, keep it in 2wd.

Thirdly, if you're routinely driving fast enough around corners that you're worried about losing traction ... maybe you should slow down.

I seriously doubt I'd roll over taking a corner too fast. Virtually every modern car on the road will not roll on level ground taking a corner too fast, it will merely slide.

As to your last comment, no argument there.

I realize it's a Jeep and you can't take 90 degree turns at 40MPH.

I got Command-Trac. I know for 4WD Low, you can't go faster than 5MPH, but what about 4WD Lock? I don't have the manual in front of me and I can't find it on Jeep's website.
