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 - POWER STEERING FLUID


Mopart ATF +4, Automatic Transmission Fluid is required in the power steering system. Substitute fluids can induce power steering system failure.


Mopart ATF +4, Automatic Transmission 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 odor that may change with age. Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change.


DESCRIPTION - ENGINE 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


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.


Mopart


Antifreeze/Coolant,


The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Year/100,000 Mile Formula (MS-9769), or the equiva- lent ethylene glycol base coolant with organic corro- sion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% Ethylene Glycol and 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solu- tion.


MoparT


Antifreeze/Coolant,


CAUTION: Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection.


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 to as high as 149°C (300°F). This temperature is hot enough to melt plas- tic and soften solder. The increased temperature can result in engine detonation. In addition, 100 percent ethylene-glycol freezes at -22°C (-8°F).


50/50 Ethylene-Glycol and Water-Is the recom- mended mixture, it provides protection against freez- ing to -37°C (-34°F). The antifreeze concentration

FLUID TYPES (Continued)


must always be 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 -67.7°C (-90°F). 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.


COOLANT SELECTION AND ADDITIVES


NOTE: Refer to the vehicle’s coolant bottle to iden- tify HOAT or Non-HOAT coolant. Non-HOAT coolant is green in color.


The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion protection. Only Mopart Antifreeze/Coolant, Year/100,000 Mile Formula (glycol base coolant with corrosion inhibitors called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water to obtain to obtain a freeze point of it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

DESCRIPTION - AUTOMATIC TRANSMISSION FLUID


NOTE: Refer to Service Procedures in this group for fluid level checking procedures.


Mopart ATF +4, Automatic Transmission Fluid is the recommended fluid for DaimlerChrysler auto- matic transmissions.


Dexron II fluid IS NOT recommended. Clutch chatter can result from the use of improper fluid.


Mopart ATF +4, Automatic Transmission 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 odor that may change with age. Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change.


DR FLUID TYPES (Continued) 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 “special” 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 additives must not be used. The use of trans- mission “sealers” should also be avoided, since they may adversely affect the integrity of transmission seals.


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.

TOWING STANDARD PROCEDURE - TOWING


A vehicle equipped with SAE approved sling-type towing equipment can be used to tow all vehicles. When towing a 4WD vehicle using a wheel-lift towing device, use tow dollies under the opposite end of the vehicle. A vehicle with flat-bed device can also be used to transport a disabled vehicle (Fig. 9).


A wooden crossbeam may be required for proper connection when using the sling-type, front-end tow- ing method.

TOWING (Continued)


A towed vehicle should be raised until lifted wheels are a minimum 100 mm (4 in) from the ground. Be sure there is adequate ground clearance at the oppo- site end of the vehicle, especially when towing over rough terrain or steep rises in the road. If necessary, remove the wheels from the lifted end of the vehicle and lower the vehicle closer to the ground, to increase the ground clearance at the opposite end of the vehicle. Install lug nuts on wheel attaching studs to retain brake drums or rotors.


RAMP ANGLE


If a vehicle with flat-bed towing equipment is used, the approach ramp angle should not exceed 15
degrees.


TOWING WHEN KEYS ARE NOT AVAILABLE


When the vehicle is locked and keys are not avail- able, use a flat bed hauler. A Wheel-lift or Sling-type device can be used on 4WD vehicles provided all the wheels are lifted off the ground using tow dol- lies.


DR


FOUR-WHEEL-DRIVE VEHICLE TOWING


Chrysler Corporation recommends that a vehicle be transported on a flat-bed device. A Wheel-lift or Sling-type device can be used provided all the wheels are lifted off the ground using tow dol- lies.


WARNING: WHEN TOWING A DISABLED VEHICLE AND THE DRIVE WHEELS ARE SECURED IN A WHEEL LIFT OR TOW DOLLIES, ENSURE THE TRANSMISSION IS IN THE PARK POSITION (AUTO- MATIC TRANSMISSION) OR A FORWARD DRIVE GEAR (MANUAL TRANSMISSION).


CAUTION: Many vehicles are equipped with air dams, spoilers, and/or ground effect panels. To avoid component damage, a wheel-lift towing vehi- cle or a flat-bed hauling vehicle is recommended.

WHEEL ALIGNMENT DESCRIPTION


NOTE: Suspension components with rubber/ure- thane bushings should be tightened with the vehi- cle at normal ride height. It is important to have the springs supporting the weight of the vehicle when the fasteners are torqued. If springs are not at their normal ride position, vehicle ride comfort could be affected and premature bushing wear may occur.


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.


Fig.1WheelAlignmentMeasurements


1 - FRONT OF VEHICLE 2 - STEERING AXIS INCLINATION 3 - PIVOT POINT 4 - TOE-IN


2 - 2 WHEEL ALIGNMENT WHEEL ALIGNMENT (Continued) OPERATION † CASTER is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the knuckle forward provides less positive caster. Tilting the top of the knuckle rearward provides more posi- tive caster. Positive caster promotes directional sta- bility. This angle enables the front wheels to return to a straight ahead position after turns (Fig. 1) † CAMBER is 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) † TOE is 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 the final front wheel alignment adjustment (Fig. 1) † THRUST ANGLE is 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)


DIAGNOSIS AND TESTING - PRE-ALIGNMENT INSPECTION


Before starting wheel alignment,


the following inspection and necessary corrections must be com- pleted. Refer to Suspension and Steering System Diagnosis Chart below for additional information.


(1) Inspect tires for size, air pressure and tread


(2) Inspect front wheel bearings for wear. (3) Inspect front wheels for excessive radial or lat-


eral runout and balance. (4) Inspect ball studs,


steering gear for looseness, roughness or binding.


(5) Inspect suspension components for wear and


linkage pivot points and

STANDARD PROCEDURE


STANDARD PROCEDURE - HEIGHT MEASUREMENT - 4WD (LD)


The vehicle suspension height MUST be measured and adjusted before performing wheel alignment pro- cedure. Also when front suspension components have been replaced. This measure must be performed with the vehicle supporting it’s own weight and taken on both sides of the vehicle.


(1) Inspect tires and set to correct pressure. (2) Jounce the front of the vehicle. (3) Measure and record the height from the ground at the centerline of the rear lower control arm bolt front tip (Fig. 2).


(4) Measure and record the height from the ground at the front spindle centerline (Static Load Radius) (Fig. 2).


(5) Subtract the first measurement from the sec- ond measurement. The difference between the two measurement should be 58 mm (2.3 inches) ± 3 mm (0.12 inches).


(6) If value is greater than 61 mm (2.4 inches), tighten the torsion bar bolt until the specification is achieved (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE).


(7) If value is less than 55 mm (2.1 inches), loosen the torsion bar bolt until the specification is achieve- d,(Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE).


(8) Repeat the previous steps until the ride height


is within specifications.

STANDARD PROCEDURE - HEIGHT ADJUSTMENT - 4WD (LD)


The vehicle suspension height MUST be measured and adjusted before performing wheel alignment pro- cedure (Refer to 2 - SUSPENSION/WHEEL ALIGN- MENT - STANDARD PROCEDURE). Also when front suspension components have been replaced. This measurement must be performed with the vehi- cle supporting it’s own weight and taken on both sides of the vehicle.


2 - 4 WHEEL ALIGNMENT WHEEL ALIGNMENT (Continued)


To adjust the vehicle height turn the torsion bar adjustment bolt CLOCKWISE to raise the vehicle and COUNTER CLOCKWISE to lower the vehicle.


CAUTION: ALWAYS raise the vehicle to the correct suspension height, NEVER lower the vehicle to obtain the correct suspension height. If the vehicle suspension height is too high, lower the vehicle below the height specification. Then raise the vehi- cle to the correct suspension height specification. This will insure the vehicle maintains the proper suspension height.


NOTE: If a height adjustment has been made, per- form height measurement again on both sides of the vehicle.


STANDARD PROCEDURE - CAMBER AND CASTER ADJUSTMENT


NOTE: 4X4 (LD) SUSPENSION HEIGHT MEASURE- MENT MUST BE PERFORMED BEFORE AN ALIGN- MENT.


NOTE: When the upper control arm pivot bolts are loosened the upper control arm will normally go inwards toward the frame automatically with the weight of the vehicle.


Camber and caster angle adjustments involve changing the position of the upper control arm incon- junction with the slotted holes in the frame brackets, Install special tool 8876 between the top of the upper control arm bracket and the upper control arm (on 1500 series 4X2 & 4X4). Install special tool 8876
between the bottom of the upper control arm bracket pressing the tool against the frame and the upper control arm (on 2500/3500 series 4X2) in order to move the upper control arm outwards for proper adjustment with the vehicle at normal ride height (Fig. 3).

angle while adjusting caster, move one pivot bolt of the upper control arm in or out. Then move the other pivot bolt of the upper control arm in the opposite direction. Install special tool 8876 between the top of the upper control arm bracket and the upper control arm (on 1500 series 4X2 & 4X4). Install special tool 8876 between the bottom of the upper control arm bracket pressing the tool against the frame and the upper control arm (on 2500/3500 series 4X2) in order to move the upper control arm outwards for proper adjustment with the vehicle at normal ride height (Fig. 3).


To increase positive caster angle, move the rear position of the upper control arm inward (toward the engine). Move the front of the upper control arm out- ward (away from the engine) slightly until the origi- nal camber angle is obtained using special tool 8876
to move the upper control arm for proper adjustment. (Fig. 3)


CAMBER


Move both pivot bolts of the upper control arm together in or out. This will change the camber angle significantly and little effect on the caster angle using special tool 8876 to move the upper control arm for proper adjustment. (Fig. 3)


After adjustment is made tighten the upper control


arm nuts to proper torque specification.


TOE ADJUSTMENT


The wheel toe position adjustment is the final


adjustment.


(1) Start the engine and turn wheels both ways before straightening the wheels. Secure the steering wheel with the front wheels in the straight-ahead position.


(2) Loosen the tie rod jam nuts.

the down position. Set the front end alignment to specifications while the vehicle is in its NOR- MALLY LOADED CONDITION.


CAMBER: The wheel camber angle is preset and


is not adjustable.


CASTER: Check the caster of the front axle for correct angle. Be sure the axle is not bent or twisted. Road test the vehicle and make left and right turn. Observe the steering wheel return-to-center position. Low caster will cause poor steering wheel returnabil- ity.


Caster can be adjusted by rotating the cams on the


lower suspension arm (Fig. 5).


NOTE: Each front wheel should be adjusted for one-half of the total toe position specification. This will ensure the steering wheel will be centered when the wheels are positioned straight-ahead.


(3) Adjust the wheel toe position by turning the


inner tie rod as necessary (Fig. 4).


(4) Tighten the tie rod jam nut to 75 N·m (55 ft.


lbs.).


(5) Verify the specifications (6) Turn off engine.


STANDARD PROCEDURE - ALIGNMENT LINK/COIL SUSPENSION
