Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Gloves, rags, flashlight.

2. Inspect and Clean

Inspect Reservoir: Remove the cap and check for any cracks or damage.
Clean Area: Wipe down the power steering reservoir and surrounding area to remove old fluid and debris for a clearer inspection.

3. Replace Damaged Hoses

Remove Hoses: Use a socket set to loosen the clamps and disconnect any hoses that show signs of wear or leaks.
Install New Hoses: Replace with OEM or high-quality aftermarket hoses, ensuring a secure fit and tightening the clamps to manufacturer specifications.

4. Repair or Replace Steering Gear

Remove Steering Gear: If the steering gear is leaking, disconnect the necessary components (steering linkage, electrical connectors) and remove it from the vehicle.
Inspect: Check for wear or damage; if needed, replace with a new steering gear.
Install New Gear: Position the new gear, reconnect all components, and ensure everything is tightened to the correct torque specifications.

5. Refill Power Steering Fluid

Refill: Pour new power steering fluid into the reservoir until it reaches the proper level.
Bleed System: Start the engine and turn the steering wheel from lock to lock several times to remove air bubbles from the system.
