Solution

1. Preparation

Tools Required: Socket set, wrench set, OBD-II scanner, fluid catch pan, power steering fluid.
Ensure the vehicle is on a level surface and the engine is turned off. Disconnect the battery for safety.

2. Power Steering Fluid Check

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level against the dipstick.
3. If low, add manufacturer-recommended power steering fluid until it reaches the proper level.
Safety Warning: Do not overfill the reservoir; this can cause foaming and reduce efficiency.

3. Inspect Power Steering System

Sub-steps:
1. Visually inspect power steering hoses for cracks or leaks.
2. Tighten any loose connections or fittings.
3. If leaks are found, replace the affected hoses or fittings.

4. Test Power Steering Pump

Sub-steps:
1. Start the engine and let it idle.
2. Listen for unusual noises from the power steering pump.
3. Use a pressure gauge to check the pump's output pressure; compare it to manufacturer specifications.
4. If the pressure is low or noise is excessive, replace the power steering pump.

5. Inspect Steering Rack

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect the steering rack for any signs of leakage or physical damage.
3. If damaged, remove and replace the steering rack.

6. Wheel Alignment Check

Sub-steps:
1. Check the front-end alignment using alignment equipment.
2. Adjust alignment as necessary to ensure proper handling and tire wear.
Safety Warning: Ensure the vehicle is properly supported before working under it.
