²American Petroleum Institute (API) (Fig. 2)
²National Lubricating Grease Institute (NLGI)
(Fig. 3)
SAE VISCOSITY RATING
An SAE viscosity grade is used to specify the vis-
cosity of engine oil. These are specified with a dual
SAE viscosity grade which indicates the cold-to-hot
temperature viscosity range. Example SAE 5W-30 =
multigrade engine oil.
DaimlerChrysler Corporation only recommends
multigrade engine oils.

API QUALITY CLASSIFICATION
This symbol (Fig. 2) on the front of an oil container
means that the oil has been certified by the Ameri-
can Petroleum Institute (API) to meet all the lubri-
cation requirements specified by DaimlerChrysler
Corporation.
GEAR LUBRICANTS
SAE ratings also apply to multigrade gear lubri-
cants. In addition, API classification defines the
lubricants usage. Such as API GL-5 and SAE 75W-
90.
LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 3) 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.
SPECIALIZED LUBRICANTS AND OILS
Some maintenance or repair procedures may
require the use of specialized lubricants or oils. Con-
sult the appropriate sections in this manual for the
correct application of these lubricants.
DESCRIPTION - AXLE
A multi-purpose, hypoid gear lubricant which con-
forms to MIL-L-2105C and API GL 5 quality specifi-
cations should be used. Mopar Hypoid Gear
Lubricants conforms to these specifications.
FRONT AXLE
²Lubricant for 186FIA (Model 30) axle is SAE
75W-140 SYNTHETIC.
REAR AXLE
²Lubricant for 198RBI (Model 35) axle is SAE
75W-140 SYNTHETIC.
²Lubricant for 8 1/4 axle is a thermally stable
SAE 75W-90. For trailer tow or heavy duty applica-
tions the lubricant should be replaced with SAE
75W-140 SYNTHETIC.
NOTE: Trac-lokTequipped axles require a friction
modifier be added to the lubricant.
CAUTION: If axle is submerged in water, lubricant
must be replaced immediately to avoid possible
premature axle failure.
DESCRIPTION - MANUAL TRANSMISSION
Mopartmanual transmission fluid is the lubricant
recommended for the NV1500 and the NV3550 trans-
missions.
DESCRIPTION - AUTOMATIC TRANSMISSION
FLUID
NOTE: Refer to the maintenance schedules in this
group for the recommended maintenance (fluid/filter
change) intervals for this transmission.
NOTE: Refer to Service Procedures in this group for
fluid level checking procedures.
MopartATF +4, type 9602, Automatic Transmis-
sion Fluid is the recommended fluid for
DaimlerChrysler automatic transmissions.
Dexron II fluid IS NOT recommended. Clutch
chatter can result from the use of improper
fluid.
MopartATF +4, type 9602, Automatic Transmis-
sion Fluid when new is red in color. 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.ATF+4 also has a unique

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.
CAUTION: Do not use coolant additives that are
claimed to improve engine cooling.
OPERATION - AUTOMATIC TRANSMISSION
FLUID
The automatic transmission fluid is selected based
upon several qualities. The fluid must provide a high
level of protection for the internal components by
providing a lubricating film between adjacent metal
components. The fluid must also be thermally stable
so that it can maintain a consistent viscosity through
a large temperature range. If the viscosity stays con-
stant through the temperature range of operation,
transmission operation and shift feel will remain con-
sistent. Transmission fluid must also be a good con-
ductor of heat. The fluid must absorb heat from the
internal transmission components and transfer that
heat to the transmission case.

WHEEL ALIGNMENT
DESCRIPTION
Wheel alignment involves the correct positioning of
the wheels in relation to the vehicle. The positioning
is accomplished through suspension and steering
linkage adjustments. An alignment is considered
essential for efficient steering, good directional stabil-
ity and to minimize tire wear. The most important
measurements of an alignment are caster, camber
and toe (Fig. 1).
CAUTION: Never attempt to modify suspension or
steering components by heating or bending.
NOTE: Periodic lubrication of the front suspension/
steering system components may be required. Rub-
ber bushings must never be lubricated. Refer to
Lubrication And Maintenance for the recommended
maintenance schedule.
OPERATION
²CASTERis the forward or rearward tilt of the
steering knuckle from vertical. Tilting the top of the
knuckle forward provides negative caster. Tilting the
top of the knuckle rearward provides positive caster.
Positive caster promotes directional stability. This
angle enables the front wheels to return to a straight
ahead position after turns (Fig. 1)
²CAMBERis the inward or outward tilt of the
wheel relative to the center of the vehicle. Tilting the
top of the wheel inward provides negative camber.
Tilting the top of the wheel outward provides positive
camber. Incorrect camber will cause wear on the
inside or outside edge of the tire (Fig. 1)²TOEis the difference between the leading inside
edges and trailing inside edges of the front tires.
Wheel toe position out of specification cause's unsta-
ble steering, uneven tire wear and steering wheel off-
center. The wheel toe position is thefinalfront
wheel alignment adjustment (Fig. 1)
²THRUST ANGLEis the angle of the rear axle
relative to the centerline of the vehicle. Incorrect
thrust angle can cause off-center steering and exces-
sive tire wear. This angle is not adjustable, damaged
component(s) must be replaced to correct the thrust
angle (Fig. 1)
