Disconnect the battery to ensure safety while working on the electrical components.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the recommended fluid if low.
Inspect the fluid for contamination (dark color or debris).

3. Inspect Steering Components

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect the steering rack for leaks, checking all hoses and connections.
Check tie rod ends for any signs of wear or excessive play.
If any components are damaged, proceed to replace them.

4. Inspect Serpentine Belt

Locate the serpentine belt and check for cracks, fraying, or signs of wear.
If the belt is damaged, remove it using a socket set to loosen the tensioner.
Replace with a new serpentine belt, ensuring proper routing.
