Solution

1. Preparation

Gather tools: socket set, fluid catch pan, power steering fluid, and a flashlight.
Ensure the vehicle is on a level surface and the engine is off.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, top off with the manufacturer-recommended power steering fluid.

3. Inspect for Leaks

Look around the power steering pump, hoses, and steering rack for signs of fluid leakage.
If leaks are found, identify the source and replace the affected component.

4. Test Power Steering Pump

Start the engine and listen to the power steering pump while turning the wheel.
If the pump is noisy, it may need to be replaced.

5. Examine Steering Rack

Check for any play or unusual movement in the steering rack while turning.
If damage is detected, replace the steering rack assembly.

6. Replace Serpentine Belt (if needed)

If the serpentine belt shows signs of wear, replace it.
Loosen the tensioner and remove the old belt, then install the new belt according to the routing diagram.
