Solution

1. Preparation

Tools Required: Socket set, torque wrench, OBD-II scanner, power steering fluid gauge, jack and jack stands.
Ensure the vehicle is on a flat, stable surface and securely lifted.
Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Replace Damaged Components

Remove the damaged steering linkage:
- Use a socket set to unbolt the tie rods and steering rack from their mounts.
- Pay attention to the orientation of components for reinstallation.
Replace with new components:
- Install new tie rods and steering rack, ensuring they align properly.
- Torque bolts to the manufacturer’s specifications (refer to the service manual for exact values).

3. Align the Steering Wheel

Center the steering wheel:
- Reinstall the steering wheel if removed, ensuring it is straight.
- Adjust any misaligned components to achieve proper alignment.
Perform a four-wheel alignment:
- Take the vehicle to a professional alignment shop to ensure all wheels are aligned according to specifications.

4. Refill and Bleed the Power Steering System

Check power steering fluid:
- Refill the reservoir with the recommended power steering fluid type for the BMW X3 F25.
Bleed the system:
- Turn the steering wheel from lock to lock several times with the engine running to remove any air pockets.

5. Final Inspection

Recheck all fasteners and components to ensure everything is secure.
Verify that the steering system operates smoothly without any unusual noises.
