3. Remove front tabbed thrust washer (1).
4. Remove input gear (1).
5. Remove rear tabbed thrust washer (2) from low
range gear (1).
CLEANING
Clean the transfer case parts with a standard parts cleaning solvent. Remove all traces of sealer from the cases
and retainers with a scraper and 3M™ all purpose cleaner. Use compressed air to remove solvent residue from oil
feed passages in the case halves, retainers, gears, and shafts.

INSPECTION
MAINSHAFT/SPROCKET/HUB
Inspect the splines on the hub and shaft and the teeth on the sprocket. Minornicks and scratches can be smoothed
with an oilstone, however, replace any part that is damaged.
Check the contact surfaces in the sprocket bore and on the mainshaft. Minornicks and scratches can be smoothed
with 320-400 grit emery cloth but do not try to salvage the shaft if nicks or wear is severe.
INPUT GEAR AND PLANETARY CARRIER
Check the teeth on the input gear (6). Minor nicks can be dressed off with an oilstone but replace the gear if any
teeth are broken, cracked, or chipped. The bearing surface on the gear can besmoothedwith300-400gritemery
cloth if necessary.
Examine the planetary carrier body (1) and pinion gears for wear or damage.The carrier will have to be replaced
as an assembly if the body, pinion pins, or pinion gears are damaged.
Check the carrier lock ring (4) and both thrust washers (2, 3) for wear or cracks. Replace them if necessary. Also
replace the carrier lock retaining ring (5) if bent, distorted, or broken.
Input Gear And Carrier Components
1 - PLANETARY CARRIER 4 - CARRIER LOCK RING
2 - REAR THRUST WASHER 5 - CARRIER LOCK RETAINING RING
3 - FRONT THRUST WASHER 6 - INPUT GEAR

LOW RANGE ANNULUS GEAR
Inspect annulus gear (2) condition carefully. The gear
is only serviced as part of the front case. If the gear is
damaged, it will be necessary to replace the gear and
front case as an assembly. Do not attempt to remove
the gear.
FRONT CASE AND REAR CASE
Inspect the cases for wear and damage.
Check case condition. If leaks were a problem, look for gouges and severe scoring of case sealing surfaces. Also
make sure the front case mounting studs are in good condition.
Check the front case mounting studs and vent tube. The tube can be secured with Loctite™ 271 or 680 if loose.

rear case. The threads can be repaired with a thread chaser or tap if necessary. Or the threads can be repaired with
Helicoil™ stainless steel inserts if required.
OIL PUMP/OIL PICKUP
Examine the oil pump pickup parts. Replace the pump if any part appears to beworn or damaged. Do not disas-
semble the pump as individual parts are not available. The pump is only available as a complete assembly. The
pickup screen, hose, and tube are the only serviceable parts and are available separately.
ASSEMBLY
BEARINGS AND SEALS
1. Remove the input shaft bearing (1) from the front
case (2) with suitable snap-ring pliers.
2. Transfer the retaining ring to the new bearing if
necessary and install the bearing into the front
case.

OIL PUMP AND REAR CASE
CAUTION: Do not remove the bolts holding the oil
pump cover to the rear case half. The oil pump
cover is aligned to the rear output shaft inner
bearing race and will become mis-aligned if the
bolts are loosened. If the transfer case failure has
generated any debris which may have become
trapped in the oil pump. the rear case and oil
pump assembly MUST be replaced.
1. Apply bead of Mopar
Gasket Maker, or equivalent,
to mating surface of front case. Keep sealer bead
width to maximum of 3/16 inch. Do not use exces-
sive amount of sealer as excess will be displaced
into case interior.
2. Align oil pump with mainshaft and align shift rail
with bore in rear case. Then install rear case (1)
and oil pump assembly.
3. Install 4-5 rear case(1)-to front case (2) bolts to
hold rear case in position. Tighten bolts snug but
not to specified torque at this time.
CAUTION: Verify that shift rail, and case alignment
dowels are seated before installing any bolts.
Case could be cracked if shaft rail or dowels are
misaligned.
4. Apply Loctite™ 242 to remainder of rear case-to-
front case bolt threads and install bolts. Tighten
bolts to 20-27 Nꞏm (15-24 ft. lbs.),
5. Install rear output bearing (2) snap-ring (3) to out-
put shaft.

SEAL BOOT
1. Install the front output shaft seal slinger with Oil Slinger Installer 8840. Install the slinger onto the shaft until the
tool contacts the rear of the output shaft.
2. Install a new seal boot clamp onto the seal boot.
3. Install the seal boot and clamp onto the slinger hub and tighten the clampwith Crimp Tool C-4975-A.
REAR EXTENSION
1. Install new seal in rear extension housing seal with
Seal Installer D-163 and universal Handle C-4171..
2. Apply bead of Mopar
Gasket Maker, or equivalent,
to mating surface of rear extension housing. Keep
sealer bead width to maximum of 3/16 inch. Do not
use excessive amount of sealer as excess could
be displaced into output bearing.
3. Align and install rear extension housing (1) on
retainer.
4. Apply Mopar
Silicone Sealer to threads of rear
extension housing bolts. Then install and tighten
bolts to 16-24 Nꞏm (12-18 ft. lbs.) torque.
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)

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.
