The front axle is a crucial component of a vehicle's suspension system, connecting the front wheels to the chassis. It supports the weight of the vehicle and allows the wheels to rotate, enabling steering and stability during movement. Typically made of steel or aluminum, the front axle can be either a solid axle or an independent suspension system. A solid axle connects both wheels directly, while an independent system allows each wheel to move independently, improving ride quality and handling. Proper maintenance of the front axle is essential for safe driving and vehicle performance.
