Mine did the same thing. The guy at the repair shop thought it was the 4wd motor. He ordered one in and it happened to be the wrong one. He then figured out that it was the computer.

Most of the time if you unhook the battery, wait a couple of min., then hook up again.
THis resets the computer, and it has worked on mine, after Ford said I was looking at
a very large repair charge.

I have a 93 jeep Cherokee, it will move in 4wh and in 4wl but will not go back into 2wd?


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)
posted here 100s of times.

http://www.rubicon-trail.com/4WD101/driveline-bind.html


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.

How do you use 4WD on a 1999 dodge durango?


there are 2 systems.
one is a part time system only.the 4x4 locks and is for ice mud and snow.Driving full time will damage the transfer case.The other system is a full time system and the selector says 2wd,4wd part time ,4wd full time and 4 lo. if in full time,it can be driven all the time even on dry roads.The full time is really an all wheel drive system.
the 4low is a very low gear and the main shifter has to be put in neutral and then the transfer case put in 4 low.attempting to put it in 4 low while in "drive" will make a gear grinding noise.
getting out of 4 low is the opposite.shifter to neutral and then put it in 2wd and then in drive.The newer durango has an electronic transfer case with a dial on the dash.The 2002 was available with 2wd,4wd,awd and 4 lo on a switch.The 1999 has the lever on the floor .

I just bought a 2004 grand cherokee V8 for my son. It has 4wd but the stick slides easily between 4wd all the time, Neutral and I'm wondering if that means it's not working? The whole point of buying was...


Not sure what you mean by "4wd all the time, Neutral".
But I can tell you how it's supposed to operate.

The three modes are 2wd, 4wd high and 4wd low. When switching between 2wd and 4wd high it makes no difference whether the Jeep is moving or in neutral. The only condition that needs to be obseved when switching from 2 to 4 high is the speed of the Jeep. It should not be done above 45mph.
The switch from 4wd high to 4wd low is a different animal. The Jeep must be stopped and in neutral. Also you should be aware that it is not a pleasant sound or feel when moving from high to low so you should worry to much about the lowed junking sound.
At times it may even be necessary to put the lever back to the high position and move the Jeep a couple feet to align gears before it goes into low.

This is the reason for the relative ease when switching from 2wd to 4wd high.
There is an art to switching from 2wd to 4wd high then to 4wd low. Once your son becomes familiar with the Jeep and begins using the different modes it will become easier.
I would like to add one more piece of advice. After building Jeeps for over 25 years and owning several I have found that 8 out of 10 times that 4wd low is used, it's used incorrectly or not needed at all. It's a good idea to find someone who has experience with 4wd to give a bit of instruction on how it should be used. Especially in the mountains.
Let me know if you need any clarification on anything.
I hope this helps.

It should tell you on the Shifter whether or not that you can Shift on the Fly. Check the Manual first if there is one in the Truck. Some Models had this and some Did not. Was an Extra from Factory Option.
