- Power steering fluid
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir under the hood.
Remove the cap and check the fluid level against the markings on the reservoir.
If low, add the appropriate type of power steering fluid as specified in the owner's manual.
Replace the cap securely.

3. Inspect and Clean Steering Components

Remove any covers or panels around the steering column if necessary.
Inspect the steering column for any debris or physical obstructions.
If any dirt or grime is present, clean the surface with a suitable cleaner and cloth.

4. Test the Power Steering Pump

Start the engine and turn the steering wheel left and right to circulate the fluid.
Listen for any unusual noises from the power steering pump.
If noises persist, the pump may need to be replaced.

5. Inspect Steering Rack
