What is stub axel?

A stub axle is a short axle that is mounted perpendicular to the wheel hub. It is often used in vehicles with independent suspension on the front wheels, such as many modern cars and trucks. The stub axle is connected to the hub assembly and rotates with it, allowing the wheels to turn. The other end of the stub axle typically connects to the steering knuckle or control arm of the suspension system. In some vehicles, the stub axle may also support the weight of the wheel and transfer power from the transmission. Stub axles are generally made of steel or other durable materials and may be solid or hollow depending on the application. They are designed to be strong and durable, with the ability to handle the loads and stresses of driving on various types of terrain.
