Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Fill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the marks on the side of the reservoir.
If low, add manufacturer-recommended power steering fluid until it reaches the appropriate level.

3. Check for Leaks

Visually inspect all power steering lines and connections for signs of fluid leaks.
If any leaks are found, replace the damaged hoses or fittings.
Clean up any spilled fluid to avoid slipping hazards.

4. Test Power Steering Pump

Start the engine and listen for unusual noises from the power steering pump.
With the engine running, turn the steering wheel from lock to lock and observe if the pump is responsive.
If noise persists or the steering does not respond smoothly, consider replacing the power steering pump.

5. Inspect Steering Rack and Pinion

Raise the front of the vehicle and secure it on jack stands.
Check the steering rack for any play or movement that shouldn't be there.
If the steering rack is damaged, it will need to be replaced.

6. Reassemble and Reconnect Battery

After all inspections and repairs, ensure all components are securely reattached.
Reconnect the negative battery terminal.
