Steer with confidence using the Beck/Arnley control arm and ball joint assembly, part number 102-6940 (also written 1026940). This front left upper unit locates the wheel and pivots the steering knuckle, combining the control arm and its ball joint in one assembly for a complete installation. It drops in as a direct-fit replacement for the 2003-2006 Mercedes-Benz S430 and 2003-2006 Mercedes-Benz S500.
Beck/Arnley builds this part to match OE form, fit, and function for foreign-nameplate applications, and it is application specific for these vehicles.
- Complete assembly: the control arm comes with its ball joint pre-installed for a single-piece installation.
- Construction: steel, iron, or aluminum depending on application, for durability and rust/corrosion resistance.
- Included where applicable: new hardware and bushings where the application calls for them.
- OE-matched: designed to match the original part's form, fit, and function.
Worn ball joints or bushings can cause clunking over bumps, loose or wandering steering, and uneven tire wear — signs this assembly may need replacing. If a failed control arm or ball joint is the cause, this replaces it. This is a front left upper position; order the matching parts for other positions as needed.
