Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lift the front using jack stands.
Disconnect the battery to ensure electrical safety.

2. Inspect and Remove Damaged Components

Inspect:
1. Visually check all components of the steering linkage, including tie rods, steering rack, and connecting joints.
2. Identify any components that show wear or damage and need replacement.
Remove:
1. Use a socket set to remove the bolts securing the tie rods to the steering rack.
2. Disconnect any electrical connectors, if applicable, to the steering assist system.
3. Carefully remove the damaged components from the linkage.

3. Install New Components

Install:
1. Position the new tie rods or steering linkage components, ensuring they are correctly oriented.
2. Hand-tighten the bolts first, then use a torque wrench to tighten them to the manufacturer's specifications (typically around 40-50 ft-lbs for tie rods).
3. Reconnect any electrical connectors if removed during disassembly.

4. Alignment and Verification

Alignment:
1. After installation, ensure the steering wheel is centered.
2. It is highly recommended to have a professional wheel alignment performed after any steering linkage work.

5. Final Checks

Reconnect the battery and perform a thorough test of the steering system.
Double-check for any leaks or unusual noises.
