A drive shaft is a mechanical component that transmits power from the engine to the wheels of a vehicle. It is typically a long, cylindrical rod made of strong materials like steel or aluminum. Drive shafts are essential in both front-wheel and rear-wheel drive systems, allowing the vehicle to move by transferring rotational energy. In many vehicles, drive shafts are connected to universal joints or CV joints to accommodate the movement of the suspension. This flexibility helps maintain a smooth drive, even on uneven surfaces. Proper maintenance of drive shafts is crucial for vehicle performance and safety.
