Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, jack and jack stands, safety goggles.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspecting components.

2. Check Fluid Level and Condition

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level against the markings.
3. Assess the fluid condition; it should be clear or light amber. Dark or milky fluid indicates contamination.
4. If the fluid is low, top it off with the manufacturer's recommended power steering fluid.

3. Replace Power Steering Fluid (if contaminated)

Sub-steps:
1. Place a fluid catch pan under the power steering pump.
2. Disconnect the return line from the pump and allow old fluid to drain into the pan.
3. Reconnect the return line securely.
4. Fill the reservoir with new power steering fluid.

4. Inspect and Replace Power Steering Pump (if faulty)

Sub-steps:
1. Remove any necessary components blocking access to the power steering pump.
2. Disconnect the power steering pump's electrical connector and fluid lines.
3. Unbolt the pump from its mounting bracket and remove it.
4. Install the new power steering pump, ensuring proper alignment and tightness.
5. Reconnect all fluid lines and the electrical connector.

5. Check Steering Rack

Sub-steps:
1. Inspect the steering rack for any signs of damage or leaks.
2. If the rack is damaged, follow manufacturer guidelines to remove and replace it.
3. Reassemble all components and check for proper function.
