DESCRIPTION
PARTS AND LUBRICANT RECOMMENDATIONS
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 1) on the label. At the bottom NLGI
symbol is the usage and quality identification letters.
Wheel bearing lubricant is identified by the letter
ªGº. Chassis lubricant is identified by the latter ªLº.
The letter following the usage letter indicates the
quality of the lubricant. The following symbols indi-
cate the highest quality.
When service is required, DaimlerChrysler Corpo-
ration recommends that only MOPARtbrand parts,
lubricants and chemicals be used. MOPARtprovides
the best engineered products for servicing
DaimlerChrysler Corporation vehicles.
AUTOMATIC TRANSMISSION FLUID - NAG1
NOTE: Refer to Service Procedures in this group for
fluid level checking procedures.
Use ATF approved to MB 236.10, MB 236.12, such
as Shell ATF 3403/M-115, MOPARtpart number
05127382AA, Fuchs/Shell ATF 3353, or equivalent.
Automatic Transmission Fluid (ATF) is red in color
when new. The ATF is dyed red so it can be identified
from other fluids used in the vehicle such as engine
oil or antifreeze. The red color is not permanent and
is not an indicator of fluid condition. As the vehicle is
driven, the ATF will begin to look darker in color and
may eventually become brown.This is normal.
FLUID ADDITIVES
DaimlerChrysler strongly recommends against the
addition of any fluids to the transmission, other than
those automatic transmission fluids listed above.
Exceptions to this policy are the use of special dyes
to aid in detecting fluid leaks.
Various ªspecialº additives and supplements exist
that claim to improve shift feel and/or quality. These
additives and others also claim to improve converter
clutch operation and inhibit overheating, oxidation,
varnish, and sludge. These claims have not been sup-
ported to the satisfaction of DaimlerChrysler and
these additivesmust not be used.The use of trans-
mission ªsealersº should also be avoided, since they
may adversely affect the integrity of transmission
seals.

AXLE FLUID
Use oils approved to MB 235.0 or 235.6, such as
Shell Spirax MB90, Caltex Hypoid LD, or MOPARt
part number 4874469, or equivalent. An API GL-5/
MIL-2105-E SAE 90 Hypoid Gear Oil may be substi-
tuted. Reduced axle durability may result if an
unapproved product is used.
BRAKE FLUID
Use brake fluid approved to MB 331.0, such as
Intac B026D, MOPARtBrake & Clutch Fluid, part
number 04549625AC, or equivalent. If the approved
product is not available, use a DOT 4 brake fluid:
minimum dry boiling point (ERBP) 500ÉF, minimum
wet boiling point (WERBP) 356ÉF, maximum viscos-
ity 1500 mm
2/s, conforming to FMVSS 116 and ISO
4925.
HOAT COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE-GLYCOL
BASE COOLANT AND IS HARMFUL IF SWAL-
LOWED OR INHALED. IF SWALLOWED, DRINK
TWO GLASSES OF WATER AND INDUCE VOMIT-
ING. IF INHALED, MOVE TO FRESH AIR AREA.
SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT
STORE IN OPEN OR UNMARKED CONTAINERS.
WASH SKIN AND CLOTHING THOROUGHLY AFTER
COMING IN CONTACT WITH ETHYLENE-GLYCOL.
KEEP OUT OF REACH OF CHILDREN. DISPOSE OF
GLYCOL BASE COOLANT PROPERLY, CONTACT
YOUR DEALER OR GOVERNMENT AGENCY FOR
LOCATION OF COLLECTION CENTER IN YOUR
AREA. DO NOT OPEN A COOLING SYSTEM WHEN
THE ENGINE IS AT OPERATING TEMPERATURE OR
HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHEN
ENGINE COMPARTMENT RELATED SERVICE IS
PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene-Glycol based coolants
is not recommended, as they provide less freeze
protection and less corrosion protection.
The cooling system is designed around the coolant.
The coolant must accept heat from engine metal, in
the cylinder head area near the exhaust valves and
engine block. Then coolant carries the heat to the
radiator where the tube/fin radiator can transfer the
heat to the air.
The use of aluminum cylinder blocks, cylinder
heads, and water pumps requires special corrosion
protection. Use coolant approved to MB 325.0, such
as EURO Peak Coolant/Anti-freeze (OLD WORLD
INDUSTRIES), Zerex G05 or G48 (The Valvoline
Company), Glysantin G05 (BASF AG), MOPARtpart
number 05066386AA, or an equivalent Extended LifeCoolant with the HOAT inhibitor system. This cool-
ant offers the best engine cooling without corrosion
when mixed with 50% anti-freeze and 50% distilled
water to obtain a freeze point of -37ÉC (-34ÉF). If it
loses color or becomes contaminated, drain, flush,
and replace with fresh properly mixed coolant solu-
tion.
CAUTION: This coolant may not be mixed with any
other type of antifreeze. Mixing of coolants other
than specified (non-HOAT), may result in engine
damage that may not be covered under the new
vehicle warranty, and decreased corrosion protec-
tion.
CAUTION: Do not use coolant additives that are
claimed to improve engine cooling.
COOLANT PERFORMANCE
The required ethylene-glycol (antifreeze) and water
mixture depends upon climate and vehicle operating
conditions. The coolant performance of various mix-
tures follows:
Pure Water-Water can absorb more heat than a
mixture of water and ethylene-glycol. This is for pur-
pose of heat transfer only. Water also freezes at a
higher temperature and allows corrosion.
100 percent Ethylene-Glycol-The corrosion
inhibiting additives in ethylene-glycol need the pres-
ence of water to dissolve. Without water, additives
form deposits in system. These act as insulation
causing temperature to rise. The increased tempera-
ture can result in engine detonation. In addition, 100
percent ethylene-glycol freezes at -22ÉC (-8ÉF).
50/50 Ethylene-Glycol and Water-Is the recom-
mended mixture, it provides protection against freez-
ing to -37ÉC (-34ÉF). The antifreeze concentration
must alwaysbe a minimum of 44 percent, year-
round in all climates. If percentage is lower, engine
parts may be eroded by cavitation. Maximum protec-
tion against freezing is provided with a 68 percent
antifreeze concentration, which prevents freezing
down to -67.7ÉC (-90ÉF). A higher percentage will
freeze at a warmer temperature. Also, a higher per-
centage of antifreeze can cause the engine to over-
heat because specific heat of antifreeze is lower than
that of water.
CAUTION: Richer antifreeze mixtures cannot be
measured with normal field equipment and can
cause problems associated with 100 percent ethyl-
ene-glycol.

LOW SPEED KNOCK
Low speed knock is generally caused by a worn
U-joint or by worn side-gear thrust washers. A worn
pinion shaft bore will also cause low speed knock.
VIBRATION
Vibration at the rear of the vehicle is usually
caused by a:
²Damaged drive shaft.
²Missing drive shaft balance weight(s).
²Worn or out-of-balance wheels.
²Loose wheel lug nuts.
²Worn U-joint(s).
²Loose/broken springs.
²Damaged axle shaft bearing(s).
²Loose pinion gear nut.
²Excessive pinion yoke run out.
²Bent axle shaft(s).
Check for loose or damaged front-end components
or engine/transmission mounts. These components
can contribute to what appears to be a rearend vibra-
tion. Do not overlook engine accessories, brackets
and drive belts.
NOTE: All driveline components should be exam-
ined before starting any repair.
DRIVELINE SNAP
A snap or clunk noise when the vehicle is shifted
into gear (or the clutch engaged), can be caused by:
²High engine idle speed.
²Transmission shift operation.
²Loose engine/transmission/transfer case mounts.
²Worn U-joints.
²Loose spring mounts.
²Loose pinion gear nut and yoke.
²Excessive ring gear backlash.
²Excessive side gear to case clearance.
The source of a snap or a clunk noise can be deter-
mined with the assistance of a helper. Raise the vehi-
cle on a hoist with the wheels free to rotate. Instruct
the helper to shift the transmission into gear. Listen
for the noise, a mechanics stethoscope is helpful in
isolating the source of a noise.
STANDARD PROCEDURE - DRAIN AND FILL
NOTE: Drain oil when warm.
(1) Clean area around oil fill plug and drain plug.
(2) Remove oil drain plug (2) and drain oil (Fig. 1).
(3) Install oil drain plug and tighten to N´m 100
(74 ft. lbs.).
(4) Remove oil fill plug (1) and fill housing up to
bottom edge of oil fill hole (Fig. 1).
(5) Install oil fill plug and tighten to N´m 100 (74
ft. lbs.).
