Help bring back steady steering and a composed ride with the SKP control arm SK521793, a front left upper control arm with ball joint that arrives with the ball joint already installed. It fits many vehicles, among them the 2006-2012 Ford Fusion, 2007-2012 Lincoln MKZ and 2006-2011 Mercury Milan. See the Buyer's Guide tab for the full list.
This control arm and ball joint assembly comes as one ready-to-install unit, so you replace the worn arm and joint together instead of servicing them separately. SKP designs it to equal or surpass OE specifications, and it is a direct-fit replacement for the listed applications.
Signs this part may need replacing include clunking or knocking from the front suspension over bumps, loose or wandering steering, excess play at the ball joint and uneven tire wear. Have the suspension inspected to confirm the cause before replacing parts.
