Renew steering precision and quiet ride quality with the MOOG Chassis Products Suspension Control Arm and Ball Joint Assembly RK80406, a front left lower unit that drops in as a direct-fit replacement for the 2000-2004 Ford Focus. It locates the front suspension and provides the pivoting ball-joint connection to the steering knuckle, with the ball joint pre-installed so you replace the arm and joint as one assembly.

  • Carbon fiber bearings: Induction-hardened studs add strength, and a patent-pending carbon fiber-reinforced bearing reduces socket friction versus typical non-reinforced bearings for longer socket life.
  • Optimized bushings: Engineered for quiet operation and resistance to wear, salt, road grime and oils.
  • Greaseable socket: Allows new lubricant to flush contaminants, easing maintenance while reducing corrosion and wear.
  • Corrosion protection: Coated studs plus e-coated cast iron and steel control arm construction help inhibit premature deterioration.

The ball stud shape is designed to compensate for sag and add swing under load, and the assembly is heat treated to match or exceed OE requirements. Laser-etched ID marks genuine MOOG quality, and it comes with all necessary hardware for installation. Precision tolerances are designed to support an easy fit and steering alignment.
