Solution

1. Preparation

Gather tools: socket set, torque wrench, power steering fluid, serpentine belt tool, and flashlight.
Ensure the vehicle is parked on a level surface with the engine off.

2. Check Power Steering Fluid

Open the hood and locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, top it off with the recommended type of power steering fluid.
Inspect the fluid condition; if it's dark or has debris, consider flushing the system.

3. Inspect and Replace Serpentine Belt

Use the serpentine belt tool to relieve tension on the belt.
Remove the belt and inspect for cracks, fraying, or glazing.
If damaged, replace the serpentine belt with a new one, ensuring proper routing and tension.

4. Examine Steering Components

Check the power steering pump for leaks. If leaking, replace the pump.
Inspect the steering rack and pinion for any abnormal wear or damage.
Tighten any loose connections and replace worn components as necessary.

5. Suspension Check

Lift the vehicle using a jack and secure it with jack stands.
Inspect ball joints and tie rods for play or damage and replace if necessary.
Reassemble any removed components securely and torque to specifications.
