MOTOR-SHIFT
DESCRIPTION
The shift motor (1) consists of a permanent magnet
D.C. motor with gear reduction to convert a high
speed-low torque device into a low speed-high torque
device. The output of the device is coupled to a shaft
which internally moves the mode and range forks that
change the transfer case operating ranges. The motor
is rated at 25 amps maximum at (23° C (72° F) with
10 volts at the motor leads.
OPERATION
The transfer case shift motor responds to the Transfer
Case Control Module (TCCM) commands to move the transfer case shift sectorbi-directionally, as required, to
obtain the transfer case operating mode indicated by the instrument panelmounted selector switch.
REMOVAL
NOTE: New shift motor assemblies are shipped in the 2WD/AWD position. If a new shift motor assembly will
be installed, it will be necessary to shift the transfer case to the 2WD/AWDposition prior to motor removal.
1. Raise the vehicle on a suitable hoist.
2. Disengage the wiring connectors from the shift motor and mode sensor.
3. Remove the bolts holding the shift motor and mode sensor assembly onto the transfer case.
4. Separate the shift motor and mode sensor assembly from the transfer case.
INSTALLATION
1. Verify that the shift sector o-ring is clean and properly positioned over the shift sector and against the transfer
case.
NOTE: Verify that the shift motor position and sector shaft orientation are aligned. It may be necessary to
manually shift the transfer case if the shift motor and sector shaft are notaligned.
2. Position the shift motor and mode sensor assembly onto the transfer case.
3. Install the bolts to hold the assembly onto the transfer case. Tighten the bolts to 16-24 Nꞏm (12-18 ft.lbs.).
CAUTION: If the original shift motor and mode sensor assembly bolts are reused, be sure to use Mopar
Lock & Seal or Loctite™ 242 to replenish the lock patch material originallyfound on the bolts
4. Engage the wiring connectors to the shift motor and mode sensor.
5. Refill the transfer case as necessary.
6. Lower vehicle and verify transfer case operation.
Radial-ply tires have the same load-carrying capacity as other types of tires of the same size. They also use the
same recommended inflation pressures.
The use of oversized tires, either in the front or rear of the vehicle, can cause vehicle drive train failure. This could
also cause inaccurate wheel speed signals when the vehicle is equipped with Anti-Lock Brakes.
The use of tires from different manufactures on the same vehicle is NOT recommended. The proper tire pressure
should be maintained on all four tires.
TIRE PRESSURE FOR HIGH SPEEDS
For proper tire pressure specification refer to the Owners Manual.
REPLACEMENT TIRES
The original equipment tires provide a proper balance of many characteristics such as:
Ride
Noise
Handling
Durability
Tread life
Traction
Rolling resistance
Speed capability
It is recommended that tires equivalent to the original equipment tires beused when replacement is needed.
Failure to use equivalent replacement tires may adversely affect the safety and handling of the vehicle.
The use of oversize tires may cause interference with vehicle components.Under extremes of suspension and
steering travel, interference with vehicle components may cause tire damage.
WARNING: Failure to equip the vehicle with tires having adequate speed capability can result in sudden tire
failure.
TIRE INFLATION PRESSURES
WARNING: Over or under inflated tires can affect
vehicle handling and tread wear. This may cause
the tire to fail suddenly, resulting in loss of vehicle
control.
Under inflation will cause rapid shoulder wear (1), tire
flexing, and possible tire failure.

SAFETY PRECAUTIONS AND WARNINGS
WARNING: Use an OSHA approved breathing filter when spraying paint or solvents in a confined area. Per-
sonal injury can result.
Avoidprolongedskincontactwithpetroleumoralcohol–basedcleaningsolvents. Personal injury can
result.
Do not stand under a hoisted vehicle that is not properly supported on safety stands. Personal injury can
result.
CAUTION: When holes must be drilled or punched in an inner body panel, verify depth of space to the outer
body panel, electrical wiring, or other components. Damage to vehicle canresult.
Do not weld exterior panels unless combustible material on the interior ofvehicle is removed from the
repair area. Fire or hazardous conditions, can result.
Always have a fire extinguisher ready for use when welding.
Disconnect the negative (-) cable clamp from the battery when servicing electrical components that are
live when the ignition is OFF. Damage to electrical system can result.
Do not use abrasive chemicals or compounds on painted surfaces. Damage to finish can result.
Do not use harsh alkaline based cleaning solvents on painted or upholstered surfaces. Damage to finish
or color can result.
Do not hammer or pound on plastic trim panel when servicing interior trim. Plastic panels can break.
DIAGNOSIS AND TESTING
WAT E R L E A K S
Water leaks can be caused by poor sealing, improper body component alignment, body seam porosity, missing
plugs, or blocked drain holes. Centrifugal and gravitational force can cause water to drip from a location away from
the actual leak point, making leak detection difficult. All body sealing points should be water tight in normal wet-
driving conditions. Water flowing downward from the front of the vehicle should not enter the passenger or luggage
compartment. Moving sealing surfaces will not always seal water tight under all conditions. At times, side glass or
door seals will allow water to enter the passenger compartment during highpressure washing or hard driving rain
(severe) conditions. Overcompensating on door or glass adjustments to stop a water leak that occurs under severe
conditions can cause premature sealwear and excessive closing or latching effort. After completing a repair, water
test vehicle to verify leak has stopped before returning vehicle to use.
VISUAL INSPECTION BEFORE WATER LEAK TESTS
Verify that floor and body plugs are in place, body drains are clear, and body components are properly aligned and
sealed. If component alignment or sealing is necessary, refer to the appropriate section of this group for proper
procedures.
WATER LEAK TESTS
WARNING: Do not use electric shop lights or tools in water test area. Personal injury can result.
When the conditions causing a water leak have been determined, simulate the conditions as closely as possible.
Ifaleakoccurswiththevehicleparkedinasteadylightrain,floodtheleak area with an open-ended garden
hose.
If a leak occurs while driving at highway speeds in a steady rain, test the leak area with a reasonable velocity
stream or fan spray of water. Direct the spray in a direction comparable to actual conditions.
If a leak occurs when the vehicle is parked on an incline, hoist the end or sideofthevehicletosimulatethis
condition. This method can be used when the leak occurs when the vehicle accelerates, stops or turns. If the
leak occurs on acceleration, hoist the front of the vehicle. If the leak occurs when braking, hoist the back of the
POSSIBLE CAUSE OF WIND NOISE
Moldings standing away from body surface can catch wind and whistle.
Gaps in sealed areas behind overhanging body flanges can cause wind-rushing sounds.
Misaligned movable components.
Missing or improperly installed plugs in pillars.
Weld burn through holes.
Improperly installed roof rack cross bars.
STANDARD PROCEDURE
BODY LUBRICATION
All mechanisms and linkages should be lubricated when necessary. This will maintain ease of operation and provide
protection against rust and excessive wear. The weatherstrip seals should be lubricated to prolong their life as well
as to improve door sealing.
All applicable exterior and interior vehicle operating mechanisms should be inspected and cleaned. Pivot/sliding con-
tact areas on the mechanisms should then be lubricated.
1. When necessary, lubricate the operating mechanisms with the specifiedlubricants.
2. Apply silicone lubricant to a clothand wipe it on door seals to avoid over-spray that can soil passenger’s cloth-
ing.
3. Before applying lubricant, the component should be wiped clean. After lubrication, any excess lubricant should be
removed.
4. The hood latch, latch release mechanism, latch striker, and safety latch should be lubricated periodically.
5. The door lock cylinders should be lubricated twice each year (preferably autumn and spring).
Spray a small amount of lock cylinder lubricant directly into the lock cylinder.
Apply a small amount to the key and insert it into the lock cylinder.
Rotate it to the locked position and then back to the unlocked position several times.
Remove the key. Wipe the lubricant from it with a clean cloth to avoid soiling of clothing.
HEAT STAKING
1. Remove trim panel.
2. Bend or move the trim panel components at the heat staked joints. Observethe heat staked locations and/or
component seams for looseness.
3. Heat stake the components.
a. If the heat staked or component seam location is loose, hold the two components tightly together and using
a soldering gun with a flat tip, melt the material securing the components together. Do not over heat the
affected area, damage to the exterior of the trim panel may occur.
b. Iftheheatstakedmaterialisbrokenormissing,useahotglueguntoapplynewmaterialtotheareatobe
repaired. The panels that are being heat staked must be held together whiletheapplyingtheglue.Oncethe
new material is in place, it may be necessary to use a soldering gun to melt the newly applied material. Do
not over heat the affected area, damage to the exterior of the trim panel mayoccur.
4. Allow the repaired area to cool and verify the repair.
5. Install trim panel.
BUZZ, SQUEAK & RATTLE
Buzz, Squeak & Rattles (BSR) may be caused by any one or more of the followingand may be corrected as indi-
cated:
Loose fasteners should be tightened to specifications.
Damaged or missing clips should be replaced.
Damaged trim panels should be replaced.
Incorrectly installed trim panels should be reinstalled properly.
Many BSR complaints such as loose trim, can be serviced using the MoparParts BSR Noise Reduction Kit. This
kit contains various tapes including foam, flock and anti-squeak used to eliminate noises caused by metal, plastic
and vinyl components. Long life lubricants and greases can also be used on avariety of components. Refer to the
Buzz, Squeak & Rattle Kit table for material contents and usage.
