RIOR/FLOOR CONSOLE - REMOVAL)
8. Remove the nuts attaching lever assembly (1) to
floorpan and remove assembly and shift cable (2).
9. Remove the shifter mechanism and cable assem-
bly from the vehicle.
INSTALLATION
1. Route the shift cable through the opening in the floor pan.
2. Position the shift mechanism over the shifter retaining studs on the floor pan.
3. Install the nuts to hold the shifter mechanism to the floor pan. Tighten the nuts to 11.86 N·m (105 in.lbs.).
4. Install any floor console components previously removed. (Refer to 23 - BODY/INTERIOR/FLOOR CONSOLE -
INSTALLATION)
5. Verify that the floor shifter is in the 4L position.
6. Raise vehicle.
7. Route the shift cable through the opening in the shift cable support bracket.
8. Install the cable and a new spring clip into the slot in the support bracket.
9. Install any additional routing clips on the shift cable.
10. Verify that the transfer case is in the 4L position. The 4L position for the transfer case is with the manual lever
to the full rearward position.
11. Attach the shift cable to the transfer case manual lever.
12. Lower vehicle and check for proper transfer case shifter operation.

TRANSFER CASE - NV241 GENII
DESCRIPTION
The NV241 GENII transfer case is a part-time transfer case with a low-range gear system. It provides three oper-
ating ranges plus a NEUTRAL position. The low range position provides a gear reduction ratio of 2.72:1 for
increased low speed torque capability.
The gear cases and extension are all of aluminum. Drive sprockets and an interconnecting drive chain are used to
transmit engine torque to the front/rear propeller shafts. The mainshaft, input gear and front output shaft are sup-
ported by ball and needle bearings.
IDENTIFICATION
An identification tag (2) is attached to the rear case of
every transfer case. The tag provides the transfer
case model number, assembly number, serial number,
and low range ratio.
The transfer case serial number also represents the
date of build.
OPERATION
OPERATING RANGE
Transfer case operating ranges are:
•
2H (2-wheel drive)
•
4H (4-wheel drive)
•
4LO (4-wheel drive low range
The 2H range is for use on any road surface at any time.
The 4H and 4LO ranges are for off road use only. They are not for use on hard surface roads. The only exception
being when the road surface is covered by ice and snow.
The low range reduction gear system is operative in 4LO range only. This range is for extra pulling power in off road
situations. Low range reduction ratio is 2.72:1.
SHIFT MECHANISM
Operating ranges are selected with a floor mounted shift lever. The shift lever is connected to the transfer case
range lever by a shift cable. A straight line shift pattern is used. Range positions are marked on the shifter knob
bezel.
SHIFTING
The transfer case can be shifted between the 2H and 4H operating ranges while the vehicle is in motion. The vehi-
cle must have the transmission placed in NEUTRAL, or the clutch depressed in the case of a manual transmission,
and be moving less than 2-3 MPH when shifting into and out of the 4L operating range.

DIAGNOSIS AND TESTING - TRANSFER CASE - NV241 GENII
Before beginning repair on a suspected transfer case malfunction, check all other driveline components beforehand.
The actual cause of a problem may be related to such items as: front hubs, axles, propeller shafts, wheels and tires,
transmission, or clutch instead. If all other driveline components are in good condition and operating properly, refer
to the Diagnosis Chart for further information.
DIAGNOSIS CHART
Condition
Possible Cause
Correction
Transfer Case difficult to shift or will
not shift into desired range.
1) Vehicle speed too great to permit
shifting.
1) Stop vehicle and shift into
desired range. Or, reduce speed to
below 3-4 km/h (2-3 mph) before
attempting the shift.
2) If vehicle was operated for an
extended period in 4H on a dry
paved surface, the driveline torque
load may be causing a bind.
2) Stop vehicle and shift the
transmission into neutral. Shift the
transfer case to 2H and operate
vehicle in 2H on dry paved
surfaces.
3) Transfer case external shift
linkage binding.
3) Lubricate, repair, or replace
linkage bushings, or tighten loose
components as necessary.
4) Insufficient or incorrect lubricant.
4) Drain and refill to edge of fill hole
with Mopar
T
ATF +4, Automatic
Transmission fluid.
5) Internal components binding,
worn, or damaged.
5) Disassemble the transfer case
and replace worn or damaged
components as necessary.
Transfer Case noisy in all operating
ranges.
1) Insufficient or incorrect lubricant.
1) Drain and refill to edge of fill hole
with Mopar
T
ATF +4, Automatic
Transmission fluid.
Noisy in, or jumps out of, four wheel
drive low range.
1) Transfer case not completely
engaged in 4L position.
1) With the transmission in
NEUTRAL, or the clutch depressed
in the case of a manual
transmission and the vehicle moving
under 3-4 km/h (2-3 mph), shift the
transfer case to NEUTRAL and then
shift into the 4L position.
2) Shift linkage out of adjustment.
2) Adjust linkage.
3) Shift linkage loose or binding.
3) Tighten, lubricate, or repair
linkage as necessary.
4) Range fork damaged, inserts
worn, or fork is binding on the shift
rail.
4) Disassemble unit and repair as
necessary.
5) Low range gear worn or
damaged.
5) Disassemble unit and repair as
necessary.
