The "front axle assembly", which uses the swing of the steering knuckle to achieve the automobile steering, is also known as the steering bridge. Located in the front of the car, it is also called the "front bridge". To ensure the safety of the vehicle, the front axle is provided with an appropriate front wheel positioning Angle.
It doesn't have to be the front wheel, it's supposed to be mounted on the steering wheel. The outer ring of the pressure bearing is rubber, which can maintain the soft connection between the body and the shock absorber, preventing the vibration from passing through the shock absorber to the body due to uneven road surface when the car is running.
But now cars are generally front wheel steering, so in fact can also refer to the front wheel bearing. But the front wheel has a lot of bearings, not all pressure bearings.
