Control Arm without ball joint suitable for Audi. Rubber-to-metal parts are used as elastic joints between chassis and body, especially in multi-link axle designs. They absorb vibrations generated by the road surface and drive units while the vehicle is in motion, contributing to driving comfort and noise insulation. Control arms link the suspension strut and bodywork, hold the strut in position, and absorb forces during acceleration, deceleration, and cornering.
