Solution

1. Preparation

Tools Required: Socket set, power steering fluid, clean rags, OBD-II scanner (if needed).
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery if you will be working on any electrical components.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level; if low, top off with the manufacturer's recommended power steering fluid.
Inspect the fluid for contamination (milky or dark coloration) indicating possible issues.

3. Inspect for Leaks

Visually inspect power steering hoses and connections for any signs of leaks.
Clean any spilled fluid and monitor for new leaks after a brief engine run.

4. Inspect and Replace Power Steering Pump Belt

Visually inspect the power steering pump belt for cracks or signs of wear.
If the belt is damaged, loosen the tensioner and replace it with a new belt, ensuring proper tension.

5. Test Power Steering Pump

Connect a pressure gauge to the power steering pump outlet (if applicable).
Start the engine and observe the pressure reading; refer to the manufacturer's specifications for normal operating pressure.
If pressure is low, consider replacing the power steering pump.

6. Examine Steering Rack

Check the steering rack for any visible damage or leaks.
If the steering rack is damaged or leaking, it may require replacement.
