Front Axle Fluid Level Check
The front axle oil level needs to be between
1/8 in (3 mm) below the bottom of the fill hole
and the bottom of the fill hole.
The front axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not over tighten the plugs as it could
damage them and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be between
1/8 in (3 mm) below the bottom of the fill hole
and the bottom of the fill hole.
The rear axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m) on
axles with aluminum housings. The rear axle fill
and drain plugs should be tightened to 22 to
52 ft lbs (30 to 70 N·m) on axles with cast iron
housings.
CAUTION!
Do not over tighten the plugs as it could
damage then and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
Transfer Case
Fluid Level Check
Inspect the transfer case for fluid leaks. If a fluid
leak is found, the transfer case fluid level can
be checked by removing the filler plug located
on the back side of the transfer case. The fluid
level should be at the bottom edge of the filler
plug hole when the vehicle is in a level position.
Adding Fluid
Add fluid at the filler hole, until it runs out of the
hole, when the vehicle is in a level position. Drain
First remove fill plug, then remove drain plug.
Recommended tightening torque for drain and
fill plugs is 15 to 25 ft lbs (20 to 34 N·m).
CAUTION!
When installing plugs, do not overtighten. You
could damage them and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
Automatic Transmission
Selection Of Lubricant
It is important that the proper lubricant is used
in the transmission to assure optimum transmis-
sion performance. Use only the manufacturer’s
recommended transmission fluid. Refer to “Flu-
ids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information. It is
important that the transmission fluid be main-
tained at the prescribed level using the recom-
mended fluid. 313

Fluid Level Check – 5.7L Engine
Check the fluid level while the transmission is at
normal operating temperature. This occurs af-
ter at least 15 miles (25 km) of driving. At
normal operating temperature the fluid cannot
be held comfortably between the fingertips.
To check the fluid level properly, the following
procedure must be used:
1. Operate the engine at idle speed and nor-
mal operating temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake, and press the
brake pedal.
4. Place the shift lever momentarily in each
gear position ending with the shift lever in
PARK.
5. Remove the dipstick, wipe it clean and
reinsert it until seated.6. Remove the dipstick again, and note the
fluid level on both sides. The fluid level should
be between the “HOT” (upper) reference holes
on the dipstick at normal operating tempera-
ture. The fluid level is only valid if there is a solid
coating of oil on both sides of the dipstick. If the
fluid is low, add as required into the dipstick
tube.
Do not overfill. After adding any quantity
of oil through the oil fill tube, wait a minimum of
two minutes for the oil to fully drain into the
transmission before rechecking the fluid level.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid
level should be between the two “COLD”
(lower) holes on the dipstick with the fluid at
approximately 70°F (21°C) (room tempera-
ture). If the fluid level is correctly estab-
lished at room temperature, it should be
between the “HOT” (upper) reference holes
when the transmission reaches 180°F
(82°C). Remember it is best to check the
level at the normal operating temperature.CAUTION!
Be aware that if the fluid temperature is below
50°F (10°C) it may not register on the dipstick.
Do not add fluid until the temperature is
elevated enough to produce an accurate
reading.
7. Check for leaks. Release parking brake.
To prevent dirt and water from entering the
transmission after checking or replenishing
fluid, make certain that the dipstick cap is
properly reseated. It is normal for the dipstick
cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in
the dipstick tube.

At Each Stop for Fuel
•Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required. Once a Month
•
Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required.
• Check the fluid levels of the coolant reser-
voir, brake master cylinder, power steering
and transmission (5.7L only) and add as
needed.
• Check all lights and other electrical items for
correct operation. At Each Oil Change
•
Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.

† This maintenance is recommended by the
manufacturer to the owner, but is not required
to maintain emissions warranty.
WARNING!
You can be badly injured working on or around
a motor vehicle. Do only that service work for
which you have the knowledge and the right
equipment. If you have any doubt about your
ability to perform a service job, take your
vehicle to a competent mechanic.
Maintenance Schedule – Diesel
Engine
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service intervals
that are required to keep your vehicle operating
properly and safely.
The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your dealer-
ship know your vehicle best, and have access
to factory trained information, genuine
MOPARparts, and specially designed elec- tronic and mechanical tools that can help pre-
vent future costly repairs.
The maintenance intervals shown should be
performed as indicated in this section.
NOTE:
Under no circumstances should oil change
intervals exceed 12,500 miles (20 000 km) or
12 months, whichever comes first.
At Each Stop for Fuel
•
Check the engine oil level about 15 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required. •
Check the fluid levels of the coolant reser-
voir, brake master cylinder, and power steer-
ing and add as needed.
• Check all lights and other electrical items for
correct operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
• Inspect for the presence of water in the fuel
filter/water separator unit.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.
