Front and rear axle adjustment
The front and rear axles of the car perceive the vertical, longitudinal and transverse forces acting between the supporting surface and the frame or the car body. The rear axle is usually driven, and the front axle is steered. Vertical forces are transmitted by the elastic elements of the suspension, and longitudinal and transverse - both the suspension and special rods.
