Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool if it has been running.

2. Replace Power Steering Fluid

Sub-steps:
- Locate the power steering fluid reservoir and remove the cap.
- Use a turkey baster or siphon to remove old fluid from the reservoir.
- Refill the reservoir with the manufacturer-recommended power steering fluid type.
- Turn the steering wheel from lock to lock to circulate the new fluid.

3. Repair or Replace Leaking Components

Sub-steps:
- If leaks are found, identify the source (hoses, pump, rack).
- Disconnect the battery again if necessary.
- For hose replacement, use a hose clamp tool to remove the old hoses and install new ones securely.
- If the power steering pump is faulty, remove the serpentine belt, unbolt the pump from its mount, and install a new pump, ensuring all mounting bolts are torqued to specifications.
- For steering rack replacement, disconnect the steering shaft, fluid lines, and mounting bolts, then install the new rack and reconnect all components.

4. Refill and Bleed System

Sub-steps:
- Ensure all connections are secure and fluid levels are topped off.
- Start the engine and let it run with the steering wheel turned from lock to lock to remove air from the system.
- Check for any leaks during this process.
