Tools you'll likely need:
* Panel removal tools: Plastic pry tools to avoid scratching the door panel.
* Screwdrivers: Phillips head and possibly flathead, depending on the screws used.
* Sockets and ratchets: Various sizes, again depending on the specific fasteners.
* New door latch assembly: Make sure you get the correct part for your specific door (front driver's side, front passenger's side, rear, etc.). Your VIN number is crucial for this.
* Possibly a torque wrench: For tightening bolts to the manufacturer's specifications.
* Wire cutters/strippers (potentially): If you need to disconnect and reconnect any electrical connectors.
* Penetrating oil (like PB Blaster): To help loosen any stubborn bolts.
General Steps (Consult your repair manual for precise steps and diagrams!):
1. Disconnect the battery: This is a crucial safety step to prevent accidental short circuits.
2. Remove the interior door panel: This usually involves removing screws around the edges of the panel, possibly some fasteners hidden under trim pieces, and carefully prying the panel away from the door. Be gentle to avoid breaking any clips.
3. Disconnect the door handle linkage and electrical connectors: Carefully disconnect the mechanical linkage connecting the interior door handle to the latch mechanism. You'll also need to disconnect any electrical connectors for power locks or interior lights. Take pictures before disconnecting to help with reassembly.
4. Remove the old door latch assembly: This is the most involved part. You'll likely need to remove several screws and bolts holding the latch mechanism in place. Pay attention to the order and position of these fasteners.
5. Install the new door latch assembly: Carefully install the new latch assembly, reversing the steps you took to remove the old one. Ensure everything is properly aligned and seated.
6. Reconnect the door handle linkage and electrical connectors: Reconnect all linkages and electrical connectors, ensuring a secure connection.
7. Reinstall the interior door panel: Carefully snap the door panel back into place and secure all the screws and fasteners.
8. Reconnect the battery: Once everything is reassembled, reconnect the battery.
9. Test the door latch: Test the door latch to ensure it operates correctly.
Important Considerations:
* Door regulators: While unlikely to be directly involved, the door regulator mechanism is often near the latch and could be affected by improper handling. Proceed with caution.
* Window regulators: Similarly, be mindful of the window regulators; you don't want to damage them while removing the door panel.
* Water intrusion: Ensure all seals are properly placed upon reassembly to prevent water damage.
This is a simplified overview. The exact steps will vary depending on your specific vehicle. Using a repair manual specific to your 2006 Ford Freestar is absolutely essential for success. If you're uncomfortable with any aspect of this repair, it's always best to consult a qualified mechanic.
