Solution

1. Preparation

Tools Required: Socket set, fluid catch pan, OBD-II scanner, pressure gauge, flashlight.
Safety Warnings: Disconnect the battery before working on electrical components. Allow the engine to cool before inspecting the power steering system.

2. Checking Power Steering Fluid

Open the hood and locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the appropriate power steering fluid if low.
Inspect the fluid for contamination (dirty or burnt smell) and change if necessary.

3. Inspecting for Leaks

Use a flashlight to visually inspect the power steering pump, hoses, and steering rack for signs of leakage.
If leaks are found, replace the affected hoses or seals as necessary.

4. Testing the Power Steering Pump

Reconnect the battery.
Start the engine and turn the steering wheel from lock to lock while observing for noise.
If noise is present, use a pressure gauge to check the pump output pressure; refer to the service manual for specification values.
If pressure is below specifications, replace the power steering pump.

5. Inspecting Steering Components

Lift the vehicle and securely support it on jack stands.
Inspect the steering rack for any visible damage or play.
Check the tie rod ends for wear; replace if any play is detected.
