Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical accidents.

2. Inspect and Top Off Power Steering Fluid

Locate the power steering fluid reservoir; it is usually near the engine bay.
Remove the cap and check the fluid level against the markings on the reservoir.
If low, add the manufacturer-recommended power steering fluid until it reaches the proper level.
Replace the cap securely.

3. Check for Leaks

Visually inspect all power steering hoses and connections for signs of fluid leakage.
If leaks are found, mark the locations for repair or replacement.
Tighten any loose connections or clamps.

4. Examine the Power Steering Pump

With the engine running, listen for any abnormal noises coming from the power steering pump.
If noise persists, inspect the pump for wear or damage, and consider replacement if needed.
Remove the pump by disconnecting the inlet and outlet hoses and unbolting it from its mount.

5. Inspect Steering Rack

Check the steering rack for leaks and physical damage.
If any issues are found, it may require replacement or repair.
To remove the steering rack, disconnect it from the steering column and unbolt it from the chassis.
