Description of wheel alignment Note: suspension components with rubber/urethane bushings should be tightened with vehicle in normal ride height. It is important to have the sources support the weight of the vehicle when the fastener is tightened. If the springs are not their usual ride, ride comfort of the car can be affected and may occur premature bushing wear. Convergence includes the correct positioning of the wheel relative to the vehicle. Positioning is done through adjustments to the suspension and steering linkage.
Alignment is necessary for efficient management, good directional stability and minimize tire wear. The most important measure of alignment are caster, camber and toe. Warning: never attempt to change the suspension or steering components by heating or bending. Note: may require periodic lubrication of front suspension/Steering system components. Rubber bushing should never be lubricated. Refer to LUBRICATION maintenance & for recommended maintenance schedule. Operation wheel alignment CASTER is forward or backward tilt of the Steering knuckle from the vertical. Tilt the top of the knuckle forward provides negative Caster. Tilt the top of the knuckle directed provides positive Caster. Positive caster promotes stability. This angle allows the front wheel to return to forward position after turns. See fig. 1 BULGE inward or outward tilt of the wheel relative to the center of the car. Tilt the top of the wheel inside has negative camber. Tilt the top of the outside wheel provides a positive camber.
Incorrect camber will wear inside or outside edge of the tire. Cm. Fig. 1 thumb the difference between leading and trailing edges inside the inside edges of the front tires. The Cape from the unreliable steering wheel, tyre wear uneven and the Centre of the steering wheel. Cape final alignment correction is steering the front wheel. See fig. 1 the thrust angle is the angle of the rear axle to the centreline of the vehicle. Wrong thrust angle can cause the center of the Steering and excessive wear of the tyres. This angle adjustable, no damaged components must be replaced to eliminate the thrust angle. Cm. Download

The oil level control is located on the electrohydraulic unit (4) and consists of the float (5) which is integrated into the electrohydraulic unit. The float is positioned to plug the opening (6) between the oil gallery (2) and gearset chamber (1) so that the rotating gearsets do not splash about in oil as the oil level rises. The oil level control reduces power loss and prevents oil from being thrown out of the transmission housing at high oil temperatures. See Fig. 182.
OPERATION FLUID LEVEL CONTROL With low oil levels, the lubricating oil which flows constantly out of the gearset, flows back to oil gallery (2) though the opening (6) If the oil level rises, the oil presses the float (5) against the housing opening (6). The float (5) therefore separates the oil gallery (2) from the gearset chamber (1). The lubricating oil which continues to flow out of the gearsets is thrown against the housing wall, incorporated by the rotating parts and flows back into the oil gallery (2) through the upper opening (arrow). See Fig. 183. DIAGNOSIS AND TESTING CAUSES OF BURNT FLUID Burnt, discolored fluid is a result of overheating which has three primary causes. Internal clutch slippage, usually caused by low line pressure, inadequate clutch apply pressure, or clutch seal failure. A result of restricted fluid flow through the main and/or auxiliary cooler. This condition is usually the result of a faulty or improperly installed drainback valve, a damaged oil cooler, or severe restrictions in the coolers and lines caused by debris or kinked lines.

CAUTION: The torque converter must be replaced if a transmission failure resulted in large amounts of metal or fiber contamination in the fluid. The torque converter is a hydraulic device that couples the engine crankshaft to the transmission. The torque converter consists of an outer shell with an internal turbine (1), a stator (3), an overrunning clutch, an impeller (2), and an electronically applied converter clutch. The converter clutch provides reduced engine speed and greater fuel economy when engaged. Clutch engagement also provides reduced transmission fluid temperatures.
The converter clutch engages in third through fifth gears. The torque converter hub drives the transmission oil (fluid) pump. See Fig. 267. A turbine damper (6) has been added for some applications to help improve vehicle noise, vibration, and harshness (NVH) characteristics. The torque converter is a sealed, welded unit that is not repairable and is serviced as an assembly. download

2001 Dodge Durango VEHICLE THEFT SECURITY SYSTEM DESCRIPTION Anti-Theft Systems – Dakota & Durango DESCRIPTION VEHICLE THEFT SECURITY SYSTEM Vehicle Theft Security System (VTSS) provides perimeter protection against unauthorized use or tampering by monitoring vehicle’s doors, ignition system and liftgate (Durango). VTSS flashes headlights and sounds horn if any door, hood or liftgate (Durango) is opened without using valid key or Remote Keyless Entry (RKE) system. VTSS is controlled by Central Timer Module (CTM). CTM is located behind left side kick panel. VTSS is also equipped with a power-up mode. If battery is disconnected or loses power while VTSS is armed, VTSS system remains armed when power is restored. A tamper alert signal is sounded on vehicle entry if VTSS was triggered while away from vehicle.
Horn will sound 3 times, alerting owner VTSS was triggered. SENTRY KEY IMMOBILIZER SYSTEM If vehicle is equipped with optional Sentry Key Immobilizer System (SKIS), ignition key will have a Gray molded rubber cap. Models not equipped with optional SKIS will have a Black molded rubber cap on the head of the ignition key. SKIS consists of the Sentry Key Immobilizer Module (SKIM), sentry transponder keys, SECURITY indicator LED and Powertrain Control Module (PCM). SKIM is located under steering column shrouds, near ignition lock cylinder. Transponder is located in ignition key. See Fig. 1 . If an invalid ignition key is used, SKIM will send invalid signal to PCM, causing engine to start and run for 2 seconds, then stop. If vehicle is started with invalid keys 6 times in a row, vehicle will shut down until correct key is used.
Mechanism of injury. The differential side gears and pinions can be checked by turning the vehicle. They usually do not cause noise during the avant-garde movement when unloading gear. Side gears are loaded during the twists and turns of the vehicle. Worn pinion shaft can also cause binding or knocking noise. Bearing noise bearings, shaft, differential and axle gear may produce noise if worn or damaged. Bearing noise may be whining, growling sound. Pinion bearings have a constant field. This noise is only changed when the speed of the vehicle. Pinion bearing noise will be higher pitched because it rotates more rapidly. Drive the car and load differential. If the bearing noise occurs, the pinion rear bearing is the source of the noise. If the bearing noise heard during the coast bearing the front gears is the source. Worn or damaged differential bearings normally produce noise low.
Differential bearing noise similar to the noise of the gear. Step differential bearing noise is constant depends only on the speed of the vehicle. Axle shaft bearings produce noise and vibrations when worn or damaged. The noise usually changes when loading the bearings. Road test the vehicle. Turn the car sharply to the left and right. This will load the bearings and change the level of noise. Where the minor axis, given the damage, the noise is usually not noticeable at speeds of 30 mph above. low detonation velocity of low detonation velocity is usually caused by wear crosses or worn side gear bearing ring. Worn pinion shaft bore is also a cause of low speed knock. VIBRATION vibration on the rear face of the vehicle, usually caused by a damaged drive shaft. There is no drive shaft balance value. Worn or balance wheel. Loose wheel lug nuts. Be a U-joint (s). Loose/broken coil springs. Damage to the axle shaft bearing (s). 2001 Dodge Ram 2500 bearing noise testing and verification Download
Use this test in combination with pressure test the fuel pump and the fuel capacity Test. check valve pump operation: the electric fuel pump outlet contains a one-way valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when the pump is not working. It is also used to keep the fuel supply line, full of gasoline when the pump is not working. After the vehicle has cooled down, the fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in the fuel supply line between the check valve and fuel injectors. Fuel pressure, which dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition.
Where is the electric fuel pump, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a warm engine, which was closed for a short period of time can be caused by: fuel pressure, bleeding in the past, injector (s). Fuel pressure, bleeding in the past, the valve in the fuel pump module. 1. disconnect the fuel line at the fuel rail. Refer to fuel tubes/lines/hoses and clamps for procedures. On some engines cleaner housing air removal may be required before the fuel line separation. 2. get the right fuel line pressure test hose tool adapter. Tool number 6539 is used for 5/16 "tubing and tool room 6631 is used for 3/8 fuel lines. Fig. 7 connect the adapter tool (typical) 3. Connect the correct fuel line pressure test hose between tool adapter disconnected fuel line and fuel rail (fig. 7). 4. connect 0-414 kPa (0-60 psi) test fuel pressure gauges (gauge set 5069) to test for the appropriate adapter tool. DRB III Scan Tool together with the PEP module pressure 500 psi port adapter and sensor test can also used instead of the fuel pressure sensor.
