1. Transfer case installation: A transfer case is a mechanical component that connects the transmission to the front and rear wheels. It is responsible for transferring power from the engine to all four wheels. In a FWD vehicle, the transfer case needs to be installed between the transmission and the front axle.
2. Driveline modifications: The driveline, which consists of the driveshaft and axle shafts, needs to be modified to accommodate the AWD system. The front and rear axles will need to be replaced with AWD-compatible axles that can transmit power to the wheels. The driveshaft will also need to be modified or replaced to fit the new driveline configuration.
3. Front axle assembly: The front axle of a FWD vehicle is typically designed for steering purposes only and doesn't transmit power. In order to convert to AWD, the front axle assembly needs to be replaced with one that includes a differential and CV (constant velocity) joints to allow for power transfer to the front wheels.
4. Rear differential installation: If the vehicle did not originally have a rear differential, one will need to be installed to distribute power to the rear wheels. The rear differential is typically mounted on the rear axle and connects to the driveshaft.
5. Driveline components: Additional driveline components such as U-joints, CV joints, and half-shafts may be needed to connect the transfer case to the front and rear axles. These components ensure smooth and efficient power transfer.
6. Suspension modifications: The suspension system may need to be modified to accommodate the new AWD components, such as the transfer case and the front axle assembly. This may involve changes to the mounting points, control arms, and other suspension components.
7. Electrical modifications: AWD vehicles typically have additional sensors, switches, and wiring to control the AWD system. These electrical modifications may be necessary to ensure proper communication and functionality of the AWD system.
It's important to note that converting a FWD vehicle to AWD is not a simple task and requires specialized knowledge, skills, and equipment. It's highly recommended to have this type of conversion performed by a qualified mechanic or automotive specialist who has experience in driveline and AWD system modifications.
