Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Safety glasses and gloves should be worn throughout the process.

2. Locate the Leak

Use a clean cloth to wipe any visible fluid from the steering components.
Refill the power steering fluid reservoir to the recommended level.
Start the engine and turn the steering wheel from lock to lock to help identify the leak area.

3. Replace Damaged Components

Hoses:
- If any hoses are found to be leaking, use a hose clamp tool to remove the affected hose.
- Install a new hose, ensuring it is properly routed and secured with clamps.
- Torque specifications for hose clamps should be verified in the service manual.
Steering Rack:
- If the steering rack is leaking, support the vehicle on jack stands and remove the wheels.
- Disconnect the steering linkage and power steering lines from the rack.
- Remove mounting bolts and carefully extract the steering rack from the vehicle.
- Replace with a new or remanufactured steering rack, ensuring all seals are properly installed.
- Reattach all connections and torque to specifications.

4. Refill and Bleed the System

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.
Check fluid levels again and add more fluid if necessary.

5. Final Inspection

Inspect all connections for leaks after refilling the system.
Ensure that the steering operates smoothly without any unusual noises.
