Purpose and Function in Suspension

The presented control arm is dedicated to the rear axle on the right side of the Audi Q5 FY generation. As a wheel guiding component, it is responsible for maintaining the correct position of the hub relative to the body, transferring loads from the road surface, and ensuring stability during acceleration, braking, and cornering.

Thanks to its factory design, the control arm works in conjunction with other suspension components such as springs, shock absorbers, and ball joints, which translates into cohesive, predictable vehicle responses and a reduction of unwanted play in the drivetrain.
