2. Inspect and Replace Leaking Components

Inspect Fluid Reservoir:
- Remove the power steering fluid reservoir cap.
- Check for cracks or damage; replace if necessary.
Check Power Steering Lines:
- Visually inspect the power steering lines for any leaks.
- If damaged, use a socket set to remove the affected line and replace it with a new one.
Examine Power Steering Pump:
- Locate the power steering pump and inspect it for leaks.
- If leaking, remove the pump by unbolting it from the bracket and disconnecting the fluid lines.
- Replace with a new pump and reassemble.
Inspect Steering Rack:
- Check the steering rack for any signs of leakage.
- If fluid is leaking from the rack, it may require resealing or replacement.

3. Refill and Bleed System

Refill the power steering fluid reservoir with the appropriate fluid (check owner’s manual for specifications).
Start the engine and turn the steering wheel from lock to lock to bleed air out of the system.
Check fluid levels again and top off if necessary.
