Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid catch pan, tire pressure gauge, multimeter.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspecting components.

2. Address Power Steering Fluid Issues

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level.
3. If low, add the recommended power steering fluid until it reaches the proper level.
4. If fluid is contaminated, proceed to flush the system.

3. Flush Power Steering System (if necessary)

Sub-steps:
1. Disconnect the return line from the power steering pump.
2. Place the return line into a fluid catch pan.
3. Start the engine and allow it to run until clean fluid flows from the return line.
4. Reconnect the return line and refill the reservoir with new fluid.
5. Bleed the system by turning the steering wheel from lock to lock several times.

4. Replace Power Steering Pump (if faulty)

Sub-steps:
1. Disconnect the battery.
2. Remove any components obstructing access to the power steering pump (e.g., belts).
3. Disconnect the power steering pump's fluid lines.
4. Unbolt the pump from its mounting bracket and remove it.
5. Install the new power steering pump and reverse the disassembly steps.
6. Refill the power steering fluid and bleed the system.

5. Inspect and Replace Steering Components (if needed)

Sub-steps:
1. Inspect the steering linkage and rack for signs of wear or damage.
2. Replace any worn or damaged components such as tie rods, steering rack, or bushings.
3. Ensure all connections are torqued to manufacturer specifications during reassembly.
