STEERING
DESCRIPTION
CAUTION: MOPART ATF+4 is to be used in the power steering system. No other power steering or auto­matic transmission fluid is to be used in the system. Damage may result to the power steering pump and system if any other fluid is used, and do not overfill.
Power steering systems consist of:
Steering column
Rack and pinion steering gear
Belt driven hydraulic steering pump
Pump pressure and return hoses
Oil Cooler
OPERATION
The steering column shaft is attached to the gear pin­ion. The rotation of the pinion moves the gear rack from side-to-side. This lateral action of the rack pushes and pulls the tie rods (4) to change the direc­tion of the front wheels.
Power assist is provided by an engine mounted hydraulic pump which supplies hydraulic fluid pressure to the steering gear (6).

DIAGNOSIS AND TESTING POWER STEERING SYSTEM
There is some noise in all power steering systems. One of the most common is a hissing sound evident at a standstill parking. Or when the steering wheel is at the end of it’s travel. Hiss is a high frequency noise similar to that of a water tap being closed slowly. The noise is present in all valves that have a high velocity fluid passing through an orifice. There is no relationship between this noise and steering performance.

POWER STEERING FLOW AND PRESSURE
The following procedure is used to test the operation of the power steering system on the vehicle. This test will provide the gallons per minute (GPM) or flow rate of the power steering pump along with the maximum relief pressure. Perform test any time a power steering system problem is present. This test will determine if the power steering pump or power steering gear is not functioning properly. The following pressure and flow test is performed using Power Steering Analyzer Tool kit 6815 and Adapter Kit 6893.
FLOW AND PRESSURE TEST
1. Check the power steering belt to ensure it is in good condition and adjusted properly.
2. Connect pressure gauge hose from the Power Steering Analyzer to adapter 6826.
3. Connect tube 6825A to Power Steering Analyzer test valve end.
4. Disconnect the high pressure hose from the power steering pump.
5. Connect the tube 6825A to the pump fitting.
6. Connect the power steering hose from the steering gear to the adapter 6826.
7. Open the test valve completely.
8. Start engine and let idle long enough to circulate power steering fluid through flow/pressure test gauge and to get
air out of the fluid. Then shut off engine.
9. Check fluid level, add fluid as necessary. Start engine again and let idle.
10. Gauge should read below 862 kPa (125 psi), if above, inspect the hoses for restrictions and repair as neces-
sary. The initial pressure reading should be in the range of 345-552 kPa (50-80 psi).
11. Increase the engine speed to 1500 RPM and read the flow meter. If the flow rate (GPM) is below specification,
(refer to pump specification chart for GPM) the pump should be replaced.
CAUTION: The following test procedure involves testing maximum pump pressure output and flow control valve operation. Do not leave valve closed for more than three seconds as the pump could be damaged.
12. Close valve fully three times and record highest pressure indicated each time. All three readings must be
above specifications and within 345 kPa (50 psi) of each other.
Pressures above specifications but not within 345 kPa (50 psi) of each other, replace pump.
Pressures within 345 kPa (50 psi) of each other but below specifications, replace pump.
13. Open the test valve and turn the steering wheel to the extreme left and right positions three times against the
stops. Record the highest pressure reading at each position. Compare readings to the pump specifications chart. If pressures readings are not within 50 psi of each other, the gear is leaking internally and must be replaced.
CAUTION: Do not force the pump to operate against the stops for more than 2 to 3 seconds at a time because, pump damage will result.

OPERATION
The gear acts as a rolling thread between the worm shaft and rack piston. The worm shaft is supported by a thrust bearing at the lower end and a bearing assembly at the upper end. When the worm shaft is turned from input from the steering column the rack piston moves. The rack piston teeth mesh with the pitman shaft. Turning the worm shaft, turns the pitman shaft, which turns the steering linkage.

1
⁄2turn (180 degrees) starting from the 45 degree position. This peak torque reading is the preload torque. The
preload torque must be within2-10in-lbs.
5. Rotate the input shaft to its center of travel (approximately 1.5 turns from either stop). Place the torque wrench on the input shaft with the handle in the vertical position. Rotate the torque wrench slowly and evenly degrees) each side of center and record the peak torque measure on or near center. This total on-center torque reading must be5-9in-lbs higher than the previously measured preload torque without exceeding a total of 17 in-lbs. The value of the total on-center minus the preload torque is defined as the meshload torque
6. If required, adjust the on-center torque by loosening the adjuster screw lock nut and turning the adjuster screw until the total on-center and meshload torque readings fall within the specified values. Turn the adjuster screw clockwise to increase and counterclockwise to decrease the torque reading. While holding the adjuster screw in place, tighten the lock nut to 34 N·m (25 ft. lbs.).

FLUID
DESCRIPTION
NOTE: It is normal that some pressure will build up inside the reservoir, especially, with a warm vehicle. A slight popping noise upon removal of the cap is normal. The fluid level should read between the ADD and the FULL COLD marks. When the fluid is hot it should read between ADD and FULL HOT marks. Only add fluid when the vehicle is cold.
The recommended fluid for the power steering system is MoparT ATF +4. MoparT ATF+4, when new is red in color. The ATF+4 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+4 will begin to look darker in color and may eventually become brown. THIS IS NOR- MAL. 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.
STANDARD PROCEDURE POWER STEERING FLUID LEVEL CHECKING
WARNING: FLUID LEVEL SHOULD BE CHECKED WITH THE ENGINE OFF TO PREVENT PERSONAL INJURY FROM MOVING PARTS.
CAUTION: MOPART ATF+4 is to be used in the power steering system. No other power steering or auto­matic transmission fluid is to be used in the system. Damage may result to the power steering pump and system if any other fluid is used, and do not overfill.
Page 69
DR/DH PUMP 19 - 69
The power steering fluid level can be viewed on the dipstick attached to the filler cap. There are two ranges listed on the dipstick, COLD and HOT. Before opening power steering system, wipe the reservoir filler cap free of dirt and debris. Remove the cap and check the fluid level on its dipstick. When the fluid is at normal ambient temperature, approximately 21°C to 27°C (70°F to 80°F), the fluid level should read between the minimum and maximum area of the cold range. When the fluid is hot, fluid level is allowed to read up to the highest end of the HOT range. Only add fluid when the vehicle is cold.
Use only MoparT ATF+4 Do not overfill the power steering system.

SWITCH-POWER STEERING PRESSURE
DESCRIPTION
A pressure sensing switch is used in the power steering system. It is mounted on the high-pressure steering hose. This switch will only be used with on HD vehicles with the 5.7L engines. There is no pressure switch used for the
3.7L, 4.7L, 5.9L engines or the 5.7L LD vehicle pump.
OPERATION
The switch is used on the 5.7L V-8 engines HD vehicles only. The power steering pressure switch provides an input to the Powertrain Control Module (PCM). This input is pro-
vided during periods of high steering pump load and low engine rpm; such as during parking maneuvers. The PCM increases the idle speed through the Idle Air Control (IAC) motor. This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the Normally Closed (NC) switch will open and the PCM will increase the engine idle speed. This will prevent the engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close and engine idle speed will return to its previous setting.
REMOVAL - 5.7L - HD VEHICLES ONLY
The power steering pressure switch (5) is installed in the power steering high-pressure hose (5).
1. Disconnect electrical connector from power steer­ing pressure switch.
2. Place a small container or shop towel beneath switch to collect any excess fluid.
3. Remove switch. Use back-up wrench on power steering line to prevent line bending.
INSTALLATION - 5.7L - HD VEHICLES ONLY
This switch is used only with the 5.7L V-8 engines HD vehicles only.
1. Install power steering switch (5) into power steering line (5).
2. Tighten to 8–11 N·m (70–100 in. lbs.) torque.

DIAGNOSIS AND TESTING - HYDRAULIC FLOW AND PRESSURE
The following procedures are used to test the operation of the power steering and hydraulic fan systems on this vehicle. These tests will provide the gallons per minute (GPM) or flow rate of the power steering pump along with the maximum relief pressure at given points in the system. Perform the first test anytime a power steering system problem is present and the second as necessary once the first test is completed. These tests will determine if the power steering pump, hydraulic fan, or power steering gear is not functioning properly. They will also determine if the flow coming out of the hydraulic fan motor is sufficient for the power steering gear. The following pressure and flow tests are performed using the Power Steering Analyzer kit 6815 (with appropriate hoses) and Adapter kit 9091. (Refer to 19 - STEERING - SPECIAL TOOLS)

2. Assemble Power Steering Analyzer as follows :
a. Gauge end (inlet) of Flow Meter And Gauge
6800 – Hose 6905, Hose 6713, Adapter Tube 9091-1
b. Valve end (outlet) of Flow Meter And Gauge
6800 – Hose 6959, Adapter Fitting 9091-3
3. Unthread pressure hose quick-connect fitting from power steering pump.
4. Connect Adapter Tube 9091-1 to pressure fitting on power steering pump.
5. Connect power steering pressure hose to Adapter Fitting 9091-3.
6. Open Analyzer test valve completely.
7. Start engine and allow to idle long enough to circulate power steering fluid through Analyzer flow meter and hoses.
8. Shut off engine and check fluid level; add fluid as necessary. Repeat Step 7 and Step 8 until air is bled from system.
9. Start engine and allow to idle.
10. Check Analyzer gauge pressure. Initial pressure reading should be 483-690 kPa (70-100 psi). If pressure is
higher, inspect hoses for restrictions and repair as necessary.
11. Increase engine speed to 1100 rpm and read Analyzer Flow Meter. The reading should be 2.6 GPM minimum.
If flow reading is below specification, replace power steering pump.
FLOW AND PRESSURE TEST - AT POWER STEERING GEAR
NOTE: This test should only be done if necessary after completing the Pump Flow And Pressure Test
1. Remove Analyzer from pump and pressure hose to fan. Reattach pressure hose to pump.
2. Assemble Power Steering Analyzer as follows :
a. Gauge end (inlet) of Flow Meter And Gauge
6800 – Hose 6959, Adapter Fitting 9091-4
b. Valve end (outlet) of Flow Meter And Gauge

8. Shut off engine and check fluid level; add fluid as necessary. Repeat Step 7 and Step 8 until air is bled from system.
9. Start engine and allow to idle.
10. Check Analyzer gauge pressure. Initial pressure reading should be 345-552 kPa (50-80 psi). If pressure is
higher, inspect hoses for restrictions and repair as necessary.
11. Increase engine speed to 1500 RPM and read Analyzer Flow Meter. The reading should be 2.4 - 2.8 GPM. If
flow reading is below specification, replace hydraulic fan.
CAUTION: This next step involves testing maximum fan motor steering relief pressure. Do not leave the valve closed for more than three seconds.
12. Close Analyzer valve fully three times for three seconds each time and record highest pressure indicated on
Analyzer gauge each time. All three readings must be within fan motor steering relief pressure specifications.
13. Completely open test valve and turn steering wheel to the extreme left and right positions against stops. Record
the highest pressure readings at each position. If pressure readings are not within 50 psi from each other, the gear is leaking internally and must be replaced.
