OIL PUMP AND REAR CASE
Lubricate the oil pump components with transmission
fluid before installation. Prime the oil pickup tube by
pouring a little oil into the tube before installation.
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. Install new o-ring in pickup tube inlet of oil pump, if
necessary.
2. Insert oil pickup tube into the oil pump.
3. 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 excessive amount
of sealer as excess will be displaced into case interior.
4. Align oil pump with mainshaft and align shift rail with bore in rear case.Then install rear case and oil pump
assembly (1).
5. Install rear output bearing snap-ring (3) to output
shaft (1).

6. Install 4-5 rear case-to front case bolts (3) to hold
rear case (1) 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.
7. Apply Mopar
Lock ’n Seal Adhesive to remainder
of rear case-to-front case bolt threads and install
bolts. Tighten bolts to 25-28 Nꞏm (18-21 ft. lbs.),
SEAL BOOT AND SHIFT MOTOR ASSEMBLY
1. Install a new seal boot clamp onto the seal boot.
2. Install the seal boot (2) and clamp onto the slinger
(2) hub and tighten the clamp with Crimp Tool
C-4975-A.
3. Position the shift motor and mode sensor assembly
onto the transfer case.
4. Install the bolts (3) to hold the shift motor and
mode sensor assembly (2) to the transfer case (1).
Tighten the bolts to 16-25 Nꞏm (12-18 ft. lbs.).

REAR EXTENSION
1. Install new seal in rear extension housing seal with
Seal Installer D-163 and Universal Handle C-4171.
Verify that the weep hole in the rubber is oriented
downward.
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 (1) on the transfer
case (2).
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. Mount transfer case on a transmission jack.
2. Secure transfer case to jack with chains.
3. Position transfer case under vehicle.
4. Align transfer case and transmission shafts and install transfer case onto the transmission.
5. Install and tighten transfer case attaching nuts to 27-34 Nꞏm (20-25 ft.lbs.) torque.
6. Connect the vent hose.
7. Connect the shift motor and mode sensor wiring connectors. Secure wire harness to clips on transfer case.
8. Align and connect the propeller shafts. (Refer to 3 - DIFFERENTIAL & DRIVELINE/PROPELLER SHAFT/FRONT
PROPELLER SHAFT - INSTALLATION) (Refer to 3 - DIFFERENTIAL & DRIVELINE/PROPELLER SHAFT/REAR
PROPELLER SHAFT - INSTALLATION)
9. Fill transfer case with correct fluid. (Refer to 21 - TRANSMISSION/TRANSFER CASE/FLUID - STANDARD PRO-
CEDURE)
10. Install skid plate, if equipped.
11. Remove transmission jack and support stand.
12. Lower vehicle and verify transfer case shift operation.
