Here's a general outline of the steps involved in converting a FWD vehicle to AWD:
1. Drivetrain Modifications:
- Remove the existing transmission and differential.
- Install a transfer case to distribute power between the front and rear wheels.
- Install a front driveshaft to connect the transfer case to the front differential.
- Install a rear driveshaft to connect the transfer case to the rear differential.
- Install a new differential for the rear axle.
2. Suspension Modifications:
- Modify the front suspension to accommodate the front driveshaft.
- Modify the rear suspension to mount the rear differential and connect the driveshaft.
- Install new axles that are compatible with the new drivetrain.
3. Driveline Components:
- Install the necessary CV joints, U-joints, and driveshafts to transmit power to the front and rear wheels.
- Install a driveshaft support and ensure proper driveline alignment.
4. Fuel and Exhaust Modifications:
- Adjust the fuel and exhaust systems to accommodate the new drivetrain components.
5. Electrical Modifications:
- Install a new wiring harness to connect the various sensors, switches, and actuators related to the AWD system.
- Program the vehicle's ECU (Engine Control Unit) to control the AWD system.
6. Testing and Calibration:
- Perform thorough testing and calibration to ensure the AWD system is functioning properly and all components are working together seamlessly.
As you can see, converting a FWD vehicle to AWD requires a comprehensive understanding of automotive engineering and drivetrain systems. It's essential to consult with experienced professionals and adhere to all safety guidelines during the conversion process to ensure the vehicle remains safe and reliable on the road.
