Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical issues.
Tools Required:
- Socket set
- Wrenches
- Power steering fluid

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Remove the cap and visually inspect the fluid level.
If low, top off with the manufacturer's recommended power steering fluid.

3. Check for Leaks

Visually inspect power steering hoses, pump, and reservoir for any signs of leakage.
Clean any leaked fluid and monitor to see if it reappears after operation.

4. Inspect Power Steering Pump

Remove any necessary components to access the power steering pump.
Check for abnormal noises from the pump while the engine is running.
If the pump is noisy, it may need to be replaced.

5. Inspect Serpentine Belt

Check the serpentine belt for fraying, cracks, or signs of wear.
If damaged, replace the belt with a new one of the same specifications.

6. Test Steering Rack

With the vehicle raised, inspect the steering rack for leaks and play.
If excessive play is present or if the rack is leaking, consider replacement.
