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.
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.
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.
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.
