Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Address Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Check fluid level; if low, top off using manufacturer-recommended power steering fluid.
If the fluid is dark or contaminated, perform a fluid flush:
1. Disconnect the return line from the power steering pump.
2. Use a catch container to drain old fluid.
3. Reconnect the return line and refill the reservoir with new fluid.
4. Start the engine and turn the steering wheel from lock to lock to purge air from the system.

3. Inspect Power Steering Pump

Locate the power steering pump and check for any visible damage or leaks.
Use a multimeter to verify the pump's electrical connections and ensure it operates correctly.
If the pump is faulty, replace it:
1. Disconnect the power steering pump from the mounting bracket.
2. Remove the power steering lines carefully.
3. Install the new pump by reversing the removal process and ensuring all connections are secure.

4. Check Steering Components

Inspect the steering rack and tie rods for wear. Replace any damaged components:
1. Use a socket set to remove the steering rack from the vehicle.
2. Replace any damaged tie rods or bushings.
3. Reinstall the steering rack and ensure all bolts are torqued to manufacturer specifications.

5. Reassemble and Test

Reconnect the battery.
Start the engine and check for any leaks in the power steering system.
Test the steering response by turning the wheel and ensuring it operates smoothly and without excessive effort.
