STEERING
DESCRIPTION
CAUTION: MOPARATF+4 is to be used in the power steering system. No other power steering or auto-
matic 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 isattached to the gear pin-
ion. 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 direc-
tion of the front wheels.
Power assist is provided by an engine mounted
hydraulic pump which supplies hydraulic fluid pressure
to the steering gear (6).

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 adapter6826.
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.
NOTE: If fluid leaked from the steering system, it should be filled to correct lervel prior to starting the
engine.
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 flowrate (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 isleaking internally and must be
replaced.
CAUTION: Do not force the pump to operate against the stops for more than 2 to3 seconds at a time
because, pump damage will result.

GEAR - INDEPENDENT FRONT SUSPENSION
DESCRIPTION
A rack and pinion steering gear is made up of two
main components, the pinon shaft and the rack. The
gear cannot be adjusted or internally serviced. If a
malfunction or a fluid leak occurs, the gear must be
replaced as an assembly.
REMOVAL
NOTE: The steering column on vehicles with an automatic transmission may not be equipped with an inter-
nal locking shaft that allows the ignition key cylinder to be locked with the key. Alternative methods of lock-
ing the steering wheel for service will have to be used.
1. Lock the steering wheel.
2. Drain and siphon the power steering fluid from the reservoir.
3. Raise the vehicle.
4. Remove and discard the steering coupler pinch bolt.
5. Remove the power steering hoses from the rack & pinion.
6. Remove the tire and wheel assembly.
7. Remove the tie rod end nuts and separate tie rod ends from the knuckles withpuller8677(Referto19-STEER-
ING/LINKAGE/TIE ROD END - REMOVAL).
8. Remove the skid plate (Refer to 13 - FRAME & BUMPERS/FRAME/FRONT SKID PLATE - REMOVAL).
9. Remove the rack & pinion mounting bolts (1).
