2002 jeep liberty front end

this is USA forum.
we dont have that car here.
nor your book on it.
is this part time 4wd, and on dry pavement/
if yes, move car to dirt, 1 tire must be on ice, dirt ,grass ?
and now you can exit 4wd, due to dive line wind up.
we dont have 2012 Cherokees here, just liberty. kinda the same.
the book on my rice jeep , says jack up one tire.(funny to read)
day 1, our cars were opted with (part time)
The Command-Trac transfer case has four positions: 2-HI, 4-HI, Neutral, and 4-LO.
or
Day 1, opted
The Selec-Trac transfer case has five positions: 2-HI, 4-HI Part-Time, 4-HI Full-Time, Neutral, and 4-LO.

they are not the same system at all.

only you know what you shifter reads, no photos by you to help
did you read your operators manual first.
it tells you how to use the box.

four wheel drive mode tells me zero.
use the correct names, seen above, are you in 4-HI
on dry pavement.
or 4-L (either)

Hello guy
try posting what 4wd system you have,? first.
command trac or select track, (the latter is full time)
part time or the full time system,
we cant guess it....
read the operators guide first, if a part time system only
as i suspect, stop driving on dry pavement.
it's only for ice, or dirt. part time. part time is not a full time system.
Command-Trac
shifting to 4wd on dry (means no ice) pavement causes, drive line wind up! and the gears to lockup. (see steering get tight in turns?> and is dangerous to drive it like this , you, me and the box)

the non grand Cherokee. early

had these choices

• 1987-2001: New Process NP231 Command-Trac, part-time only, 2.72:1 ratio with low range

NP231 has the following settings: 2HI, 4HI, N, 4LO

• 1987-2001: New Process NP242 Selec-Trac, full-time or part-time, 2.72:1 ratio with low range

NP242 has the following settings: 2HI, 4 full-time, 4 part-time, N, 4LO


as you can see you need to first know, what NP box you have or
photo your shift lever for 4wd, an post it and we tell you.

more facts, on select trac. (totally unlike command trac)
Selec-Trac locking hub is used on 4WD Cherokee. Selec-Trac
utilizes a non-disconnect front axle. Engagement of 2WD or 4WD is
accomplished at transfer case by means of mechanical shift linkage.
System allows full or part time 4WD. Selec-Trac can be shifted into
2WD or 4WD modes from inside the vehicle at any speed.
unquote
next from the service manual,
4WD TO 2WD
1) Place mode select switch in 2WD position. Transfer case
should shift to 2WD and not allow shifting into 4WD or LO range. Axle
should shift after transfer case shifts.
2) To determine if front axle has completed a shift out of
4WD into 2WD, position mode select switch back to 4WD position while
operating vehicle at slow speed. If vehicle shifts into 2WD, axle will
ratchet. If shift is not completed, transfer case will shift into 4WD
and hissing sound will come from mode select switch.
end quote.

if unsure read the FSM book its free.
shows you both systems and how to diagnose it.

in the box, click Cherokee,,then click 1993, and behold.
the real deal.

"The Liberty is available with either a part-time Command-Trac or full-time Selec-Trac transfer case."

which one?
do you have , and are very much different.

the part time only shifts on dirt or ice.
are you on dry pavement, if yes, raise the rear axle again
and shift into 2H.
4H an 4L are for iCe roads or dirt only,
or it winds up and binds up,..

selec-trac has a center differential. and does not do that above tricks.(has others...)

driving on what?
ice, snow, pavement, dry ,wet
?
what system do you have,?
The Liberty is available with either a part-time Command-Trac or full-time Selec-Trac transfer case.

we cant guess this, and is an OPTION new
so.....
read the operators guide in your glove box first. to see
if you can drive on pavement, in the mode you selected and
unstated by you.

The Liberty is available with either a part-time Command-Trac or full-time Selec-Trac transfer case.

which system ? its and option new, and we can not guess that.

part time? or full time. 4wd.
driving on what road, pavement, ice, snow, offroad, gravel roads. what?

Assuming this is an automatic transmission and that I have understood the question it sounds like you\'re stuck in 4 wheel drive? Are you able to still drive it or your stuck in 4 wheel and the transfer case is frozen or is it that you just can\'t get it out of 4 wheel! If you remove the U-boat between the transfer case and the front difference can you get the transfer case to spit? If not it would sound like either your front different is frozen (in which case you will want to replacing the grease / oil in your front different. If you disconnect the rear drive shift from transfer case and you can\'t get any movement from the transfer case then your transfer case has issues. This to can have the transfer case drained and oil replaced. Aside from. that, I woukd consider taking it to a shop as there could be multiple reasons for this and DYI\'ing could lead to more harm than good. With out seeing the vehicle and going by your brief question, I\'m finding it a little tough coming g up with any solution since the question is very vague. Having said that that\'s the best I can come up with. More and in depth description may be more helpful. I wish I could help more. Just though of one last question, does this Jeep have automatic, or manual front differential locks. Could the diff locks be stuck. Sorry I haven\'t been much more help but I am trying with what little info I have of the problem. Best of luck and for myself and others it would make it easier to help you resolve the problem. I wish you the best!

Inside the ECM/PCM. Dodge,Chrysler, and Jeep. Used to have separate TCM's. But now the integrated in to the power train control module. PCM. what is your problem?

part time or awd ?
do no engage part time 4wd on dry pavement.!! only on ice or dirt.
do post what your tires are touching? dirt or pavement????????

if stuck in 4L , on dry pavement , pull over to side of road, dirt
then shift out. if no dirt anywhere? sand or gravel or grass.?
then jack up one wheel then deselect 4Low. back do 2WD
options for your car, (do post what you have)
qoute sales brochure:
Those going 4WD can enjoy the standard Command-Trac II, or opt for the Selec-Trac II, featuring full-time AWD, 4WD Lo and a rearward-biased torque split. (end quote)

how you drive both cars, varies greatly.
in your glove box is an operators guide , did you read that yet
under how to drive in 4wd or awd.??????????

The NP231 transfer case, named "command-trac"
or
The NP242 transfer case, names "selec-trac"

if select trac, do say so
if old command trac, part time 4wd you messed up.
never put car in 4wd on dry pavement.

driving on what.?
dirt.
ice
or dry pavement. (dry means no ICE !!!)

the operators guide explains this.
here is better
