Restore precise front-suspension geometry with the Beck/Arnley Suspension Control Arm and Ball Joint Assembly 102-6940 (also written 1026940). This front left upper unit drops in as a direct-fit replacement for the 2003-2006 Mercedes-Benz S430 and 2003-2006 Mercedes-Benz S500 — see the Buyer's Guide tab for engine-level details. The control arm locates the wheel and pivots through its travel, while the pre-assembled ball joint provides the steering pivot, so worn bushings, a loose or clunking ball joint, uneven tire wear, or steering wander are signs the original may need replacing.

  • Control arm with ball joint: ships as a complete assembly for a one-piece installation.
  • OE-matched design: built to Beck/Arnley requirements to match the original part's form, fit, and function for foreign-nameplate applications.
  • Durable construction: made from steel, iron, or aluminum depending on the application, for strength and corrosion resistance.
  • New hardware and bushings: included where applicable; consult the vehicle service information for correct fasteners and torque.
