Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Drain Steering Fluid

Locate the steering fluid reservoir and use a turkey baster or siphon to remove old fluid.
Dispose of the fluid properly according to local regulations.

3. Inspect and Replace Seals

Inspect Seals:
- Remove any protective covers around the steering rack to access the seals.
- Check the condition of the input and output seals for wear or damage.
Replace Seals:
- Use a seal puller to carefully remove the damaged seals.
- Clean the sealing surfaces using a lint-free cloth to remove any debris.
- Apply a thin layer of compatible grease on the new seals before installation.
- Install the new seals, ensuring they sit evenly without pinching.

4. Replace Damaged Hoses

Remove Old Hoses:
- Use a socket set to loosen and remove the clamps securing the hoses to the steering rack.
- Carefully detach the hoses from the steering rack and the reservoir.
Install New Hoses:
- Position the new hoses and secure them with clamps at the appropriate torque specifications (usually around 10-15 ft-lbs).
- Ensure all connections are tight to prevent leaks.

5. Refill and Bleed the System

Refill the steering fluid reservoir with the manufacturer's specified fluid type.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid levels again and add more if necessary.

6. Final Inspection

Inspect all connections for leaks after the system is bled and the vehicle is off.
Clean any spilled fluid to avoid potential hazards.
