1. Open the hood.
NUMBER: 19-011-04
GROUP: Steering
DATE: December 7, 2004
2. Remove the cap from the power steering fluid reservoir.
3. Using a siphon pump/suction gun, remove as much power steering fluid as possible
from the power steering fluid reservoir.
4. Remove and save the constant tension spring clamp securing the power steering
return line hose to the power steering fluid reservoir.
5. Remove the rubber hose portion of the power steering return line from the power
steering fluid reservoir fitting.
6. Drain the power steering fluid reservoir into an appropriate container.
NOTE: This fluid should not be reused to avoid introducing contamination from the
container.
7. Raise the vehicle on an appropriate hoist.
8. Remove the fuel vapor canister.
9. Locate the bracket connecting the power steering return line cooler loop to the cradle
reinforcement plate (Fig. 1).

10. Remove the fasteners connecting the cooler line to the reinforcement plate. Save the
fasteners for use in Step #17.
11. Locate the bracket connecting the power steering pressure line to the cradle
reinforcement plate (Fig. 1).
12. Remove the fastener connecting the bracket to the reinforcement plate. Save the
fastener for use in Step #18.

13. Remove and discard the J/U nut clip on the bracket.
14. Locate and unscrew the tube nut connecting the power steering return line to the
steering gear pinion housing.
NOTE: The tube nut will remain loosely assembled to the power steering return line.
15. Drain the remaining fluid into an appropriate container and discard the loop cooler line
that was removed from the vehicle.
NOTE: This fluid should not be reused to avoid introducing contamination from the
container.
16. Install the new power steering return line, p/n 04743473AE. Attach the power steering
return line tube nut to the steering gear pinion housing and tighten to 27.1 - 35.0 N·m
(240 - 310 in. lbs.).
17. Reuse the fastener removed in Step #10. Install the fastener into the left weld nut on
the cooler fin pack bracket and the left hole in the cradle reinforcement plate. Tighten
the fastener to 9 - 11.3 N·m (80-100 in. lbs.) (Fig. 2).

18. Line up the pressure line bracket and the right weld nut in the cooler fin pack bracket.
Reuse the fastener removed in Step #12. Install the fastener through the right hole in
the cradle reinforcement plate, the fin pack bracket and the pressure line bracket.
Tighten the fastener to 9 - 11.3 N·m (80-100 in. lbs.) (Fig. 2).
19. Install the fuel vapor canister.
20. Lower the vehicle.
21. Install the constant tension spring clamp removed in Step #4 onto the rubber hose on
the power steering return line. Slide the clamp so that it is 3 inches from the end of the
rubber hose.

22. Push the end of the rubber hose portion of the power steering return line onto the
power steering fluid reservoir suction port. Secure the hose by sliding the constant
spring tension clamp installed on the hose in the last step, to within 6 mm (0.25 in.) of
the end of the rubber hose.
Be sure the hose clamp is installed past the bead on fluid reservoir fitting.
23. Fill the power steering system. Refer to Steering/Pump - Standard Procedure at the
end of this bulletin.
24. Test drive the vehicle in the parking lot. Determine if the sound, as describe in the
Symptom/Condition section of this bulletin, is still present.
25. If the sound is no longer present. The repair is complete. If the sound is still present,
replace the steering gear using the appropriate part number according to the Parts
Required table above. Refer to the service information available in TechCONNECT.
Refer to 19 - Steering/Gear - Removal and Installation.
26. Fill the power steering system. Refer to Steering/Pump - Standard Procedure below.
STEERING/PUMP - STANDARD PROCEDURE
WARNING:FLUID LEVEL SHOULD BE CHECKED AND ADJUSTED WITH ENGINE
OFF TO PREVENT INJURY FROM MOVING ENGINE COMPONENTS.
CAUTION: Use only Mopar® ATF+4 Automatic Transmission Fluid (MS-9602) in
power steering system. Use of other Mopar® power steering fluids
(MS5931 and MS9933) should be avoided to ensure peak performance of
the power steering system under all operating conditions. Do not overfill.
Read the fluid level through the side of the power steering fluid reservoir. The fluid level
should be within "FILL RANGE" when the fluid is at a temperature of approximately 21°C
to 27°C (70°F to 80°F).
1. Wipe the filler cap and area clean, then remove the cap.
2. Fill the fluid reservoir to the proper level and let the fluid settle for at least two (2)
minutes.
3. Start the engine and let run for a few seconds, then turn the engine off.
4. Add fluid if necessary. Repeat the above steps until the fluid level remains constant
after running the engine.
5. Raise the front wheels off the ground.
6. Start the engine.
7. Slowly turn the steering wheel right and left, lightly contacting the wheel stops.
8. Add fluid if necessary.
9. Lower the vehicle, then turn the steering wheel slowly from lock-to-lock.
10. Stop the engine. Check the fluid level and refill as required.
11. If the fluid is extremely foamy, allow the vehicle to stabilize a few minutes, then repeat
the above procedure.
