Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, wrench set, power steering fluid, fluid catch pan.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to avoid electrical issues while working on the steering system.

2. Inspect Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir.
- Remove the cap and check fluid level against the markings on the reservoir.
- If low, add the appropriate type of power steering fluid (consult the owner’s manual).
- Inspect the fluid for contamination (milky appearance or burnt smell).

3. Check for Leaks

Sub-steps:
- Visually inspect power steering hoses and connections for any signs of leaks.
- Look under the vehicle for puddles or wet spots near the power steering components.
- If leaks are found, replace the damaged hose or component.

4. Test Power Steering Pump

Sub-steps:
- Reconnect the battery.
- Start the engine and turn the steering wheel from lock to lock, listening for abnormal noises.
- Using a pressure gauge, connect it to the power steering pump outlet and measure the pressure while turning the wheel.
- If the pressure is below specifications, replace the power steering pump.

5. Inspect Steering Linkage

Sub-steps:
- Jack up the front of the vehicle and secure it with jack stands.
- Inspect the tie rods, ball joints, and steering rack for wear or damage.
- If components are worn, replace them as necessary.

6. Verify Tire Condition and Pressure

Sub-steps:
- Use a tire pressure gauge to check all tire pressures and inflate them to the recommended levels.
- Inspect tires for uneven wear patterns or damage.
- Rotate or replace tires if necessary.
