The rear upper forward suspension control arm is a direct-fit replacement for 2017-2026 Porsche, Audi vehicles. A control arm links the steering knuckle to the frame or subframe and lets the wheel travel up and down while holding its alignment. When an arm or its bushings wear out, the wheel can shift under braking and cornering, so replacement is the usual repair for clunks and drifting alignment. Length is 14 in.
