Here's a *general* overview of what's involved. This is not a step-by-step guide; it only highlights the complexities.
1. Diagnosis:
* Identify the problem: Is the subframe bent, cracked, or rusted through? Is the damage repairable, or does it need replacement? A proper inspection is crucial. A professional mechanic should assess the damage.
2. Preparation:
* Safety first: Disconnect the battery. Use jack stands securely to support the vehicle.
* Component removal: This involves disconnecting and removing numerous components connected to the subframe: steering components (tie rods, control arms, etc.), brakes (calipers, rotors), suspension components (struts, springs, etc.), exhaust system, wiring harnesses, and potentially engine mounts (depending on the extent of the damage). Detailed diagrams and service manuals are essential.
3. Repair or Replacement:
* Repair (if possible): This usually involves welding, which requires specialized equipment and expertise. Small cracks might be weldable, but significant damage usually necessitates replacement.
* Replacement: This involves carefully removing the damaged subframe and installing a new one. Alignment is critical; slight misalignment can severely affect handling and tire wear. This requires precision and specialized tools.
4. Reassembly:
* Install the new or repaired subframe: Ensure correct alignment and secure fastening. Torque specifications must be followed precisely.
* Reinstall all components: Reattach everything removed earlier, paying close attention to proper torque specifications and alignment.
* Alignment: A professional wheel alignment is absolutely mandatory after subframe repair or replacement.
Tools and Equipment Required (partial list):
* Jack and jack stands: For safe vehicle support.
* Socket set, wrenches, etc.: For removing and installing components.
* Torque wrench: Essential for proper tightening of bolts.
* Welding equipment (if repairing): MIG welder, appropriate welding wire, etc. This requires expertise.
* Wheel alignment equipment: For precise alignment after the repair.
* Service manual: Absolutely essential for detailed procedures and torque specifications.
* Parts: New subframe (if needed), bolts, nuts, etc.
In Conclusion: Fixing a front subframe is a major job requiring specialized knowledge, tools, and skills. It's strongly recommended to take your Ford Taurus to a qualified mechanic or body shop for this type of repair. Attempting it yourself could result in serious damage, injury, or even death.
