Refresh a worn front corner with the MOOG Chassis RK623903 control arm, a front left lower control arm and ball joint assembly that locates the wheel and integrates the ball joint into a single serviceable unit. It fits many vehicles, among them the 2009-2017 Chevrolet Traverse, 2007-2016 GMC Acadia and 2008-2017 Buick Enclave; see the Buyer's Guide tab for the full list.

  • Carbon fiber bearing: A patent-pending carbon fiber-reinforced bearing paired with induction-hardened studs reduces socket friction versus non-reinforced bearings for longer socket life.
  • Greaseable socket: Lets fresh lubricant flush contaminants for easier maintenance and reduced wear.
  • Sealed against grit: A pre-installed dust boot seal forms a barrier against wear-causing contaminants, with specially engineered coatings applied to metal surfaces to inhibit corrosion from rain, snow, salt and road grime.
  • Premium bushings & hardware: Pre-installed bushings with optimized stiffness help inhibit noise, and all necessary hardware is included for easy, fast installation.

Studs are induction hardened to resist breakage and improve fatigue life, and a laser-etched ID marks genuine MOOG quality. A worn control arm or ball joint may show clunking, wandering steering, or uneven tire wear.
