- OBD-II scanner
- Inspection mirror
- Power steering fluid
Safety Warnings:
- Disconnect the battery before working on electrical systems.
- Allow the vehicle to cool down before inspecting components.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the "min" and "max" markings.
If low, top off with the appropriate type of power steering fluid as specified in the owner's manual.

3. Inspect for Leaks

Examine the power steering hoses and connections for any signs of leaks.
Use a shop towel to wipe down the hoses and connections, then look for fresh fluid after a short period.
If leaks are found, tighten loose connections or replace damaged hoses as needed.

4. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn on the ignition and read any error codes related to the steering system.
Document any codes found and research them for potential issues.

5. Inspect Steering Components

With the vehicle raised on jack stands, visually inspect the steering linkage and tie rod ends for signs of wear or damage.
Check that all components are securely fastened and that there is no excessive play.

6. Test Power Steering Pump

Start the engine and turn the steering wheel from lock to lock.
Listen for any unusual noises from the power steering pump, which may indicate failure.
If the pump is noisy or not providing assist, it may need to be replaced.
