Solution

1. Preparation

Gather tools and parts: Ensure you have all necessary tools and replacement parts.
Safety precautions: Disconnect the battery to avoid electrical issues and allow the engine to cool before starting.

2. Identify and Replace Leaking Components

Inspect Power Steering Pump:
- Remove any covers obstructing access.
- Use a socket set to remove the pump mounting bolts.
- Disconnect the power steering hoses carefully; use a rag to catch any residual fluid.
Check the Hoses:
- Inspect hoses for cracks or pinholes. If damaged, replace with new hoses.
- Use hose clamps to secure connections properly.

3. Replace O-Rings and Seals

Remove the old O-rings from the pump and steering gear.
Clean the surfaces where O-rings sit with a clean cloth.
Lubricate new O-rings with power steering fluid and install them carefully.

4. Refill and Bleed the Power Steering System

Reconnect all hoses and ensure they are securely fastened.
Refill the power steering fluid reservoir with the recommended fluid type (check the owner’s manual).
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.

5. Final Inspection

Check for leaks around the repaired areas after the vehicle has been running for a few minutes.
Top off fluid if necessary after confirming no leaks.
