Firm up steering response and restore proper front-suspension geometry with the SKP Suspension Control Arm and Ball Joint Assembly (SK521793). This is the front left upper control arm with a ball joint already pressed in, and it drops in as a direct-fit replacement for the 2006-2012 Ford Fusion, 2007-2012 Lincoln MKZ, 2006 Lincoln Zephyr, 2003-2008 Mazda 6, and 2006-2011 Mercury Milan (see the Buyer's Guide tab for engine-level fitment).

  • Pre-assembled convenience: the ball joint arrives already installed in the arm, so you replace both worn components in one step and simplify the repair.
  • Built to OE-level tolerances: made from high-quality materials designed to meet or exceed OE specifications for long-lasting performance under everyday driving.
  • Installation hardware: includes the mounting hardware shown for a more straightforward install, reducing the need to source extra parts.
  • Handling and ride: replacing worn control arms and ball joints helps locate the suspension correctly, supporting precise handling, control, and a smoother, more comfortable ride.

Signs the original may need replacing include clunking on acceleration, deceleration, or over bumps, loose or wandering steering, and uneven tire wear. If a worn upper control arm or ball joint is the cause, this assembly replaces it.
