Condition Possible Cause Correction
Lubricant leaking from output shaft
seal or vent.1) Transfer case overfilled. 1) Drain lubricant to the correct
level.
2) Vent closed or restricted. 2) Clear or replace vent as
necessary.
3) Output shaft seals damaged or
installed incorrectly.3) Replace seal as necessary.
Check to ensure that another
component, the propeller shaft slip
yoke for example, is not causing
damage to seal.
Abnormal tire wear. 1) Extended operation on hard, dry
surfaces in the 4H position.1) Operate vehicle in the 2H
position on hard, dry surfaces.
REMOVAL
1. Raise and support vehicle.
2. Remove skid plate, if equipped. (Refer to 13 - FRAMES & BUMPERS/FRAME/TRANSFER CASE SKID PLATE
- REMOVAL)
3. Position drain oil container under transfer case.
4. Remove transfer case drain plug and drain lubricant into container.
5. Disconnect vent hose and transfer case position sensor connector.
6. Disconnect shift rod from grommet in transfer case shift lever, or from floor shift arm whichever provides easy
access. Use channel lock style pliers to press rod out of lever grommet.
7. Support transmission with jack stand.
8. Mark front and rear propeller shafts for assembly reference.
9. Remove front and rear propeller shafts. (Refer to 3 - DIFFERENTIAL & DRIVELINE/PROPELLER SHAFT/PRO-
PELLER SHAFT - REMOVAL)
10. Support transfer case with suitable jack. Secure transfer case to jackwith safety chains.
11. Remove nuts attaching transfer case to transmission.
12. Move transfer case assembly rearward until free of transmission outputshaft.
13. Lower jack and move transfer case from under vehicle.
DISASSEMBLY
Position transfer case in a shallow drain pan. Remove drain plug and drain any remaining lubricant remaining in
case.

SHIFT FORKS AND MAINSHAFT
1. Shift transfer case into NEUTRAL.
2. Remove nut that retains the shift lever to sector
shaft. Then remove shift lever (3) and spacer from
the shaft.
3. Remove the sector support (2) with Socket 9033.
4. Remove the transfer case position sensor or switch
(2) from the front case half (1).
5. Loosen detent plug (2).

13. Install the transfer case position sensor or switch
(2). Tighten the sensor or switch to 20-34 Nꞏm
(15-25 ft. lbs.) torque.
14. Install manual shift lever (3)and spacer onto sec-
tor shaft (1).
15. Install washer and nut on sector shaft to secure
shift lever. Apply 1-2 drops Mopar
Lock N’ Seal,
or equivalent, to nut threads before installation.
Then tighten nut to 27-34 Nꞏm (20-25 ft. lbs.)
torque.
16. Install new o-ring (1) on detent plug (2).

6. Install the extension housing boot and seal assem-
bly with Seal Installer 9037 (3) and Universal Han-
dle C-4171 (2).
7. Install the front companion flange onto the front
output shaft.
8. Install two bolts 180° apart into the front output
shaft companion flange.
9. Place holder (1) over the bolts (2) and against the
companion flange.
10. Install a new front companion flange nut. Tighten
the companion flange nut to 176-271 Nꞏm
(130-200 ft.lbs.).
INSTALLATION
1. Align and seat transfer case on transmission. Be sure transfer case input gear splines are aligned with trans-
mission output shaft. Align splines by rotating transfer case rear outputshaft yoke if necessary. Do not install any
transfer case attaching nuts until the transfer case is completely seatedagainst the transmission.
2. Install and tighten transfer case attaching nuts. Tighten nuts to 30-41Nꞏm (20-30 ft.lbs.).
3. Remove jack stand from under transmission.
4. Align and connect propeller shafts. (Refer to 3 - DIFFERENTIAL & DRIVELINE/PROPELLER SHAFT/PROPEL-
LER SHAFT - INSTALLATION)
5. Connect vent hose and transfer case position sensor connector.
6. Connect shift rod to transfer case lever or floor shift arm. Use channel lock style pliers to press rod back into
lever grommet.
7. Adjust shift linkage, if necessary.
8. Fill transfer case with recommended transmission fluid and install fillplug.

9. Install skid plate, if equipped. (Refer to 13 - FRAMES & BUMPERS/FRAME/TRANSFER CASE SKID PLATE -
INSTALLATION)
10. Lower vehicle

SENSOR-POSITION
DESCRIPTION
The transfer case position sensor is an electronic device whose output canbe interpreted to indicate the transfer
case’s current operating mode. The sensor consists of a five position, resistive multiplexed circuit which returns a
specific resistance value to the Powertrain Control Module (PCM) for eachtransfer case operating mode. The sen-
sor is located on the top of the transfer case, just left of the transfer casecenterline and rides against the sector
plate roostercomb. The PCM supplies 5VDC (+/- 0.5V) to the sensor and monitors the return voltage to determine
the sector plate, and therefore the transfer case, position.
OPERATION
Operating Mode Versus Resistance

44L208-213
5 NOT USED 60-61
During normal vehicle operation, the Powertrain Con-
trol Module (PCM) monitors the transfer case position
sensor return voltage to determine the operating mode
of the transfer case. Refer to the Operating Mode Ver-
sus Resistance table for the correct resistance for
each position.
REMOVAL
1. Raise and support the vehicle.
2. Disengage the transfer case position sensor connector from the positionsensor.
3. Remove the position sensor from the transfer case.
Position Sensor Linear Movement
1 - POSITION 1 - 10mm ±0.5mm
2 - POSITION 2 - 12mm ±0.5mm
3 - POSITION 3 - 14mm ±0.5mm
4 - POSITION 4 - 16mm ±0.5mm
5 - POSITION 5 - 18mm ±0.5mm
6 - POSITION 6 - 20mm±0.5mm - FULL EXTENSION

INSTALLATION
1. Inspect the o-ring seal on the transfer case position sensor. Replace the o-ring if necessary.
2. Install the transfer case position sensor into the transfer case. Torque the sensor to 27 Nꞏm (20 ft.lbs.).
3. Engage the transfer case position sensor connector to the position sensor.
4. Lower vehicle.
5. Verify proper sensor operation.
