Detailed Description

Delphi TC6841 is engineered for the rear lower forward suspension location and is listed for Mercedes-Benz GLA250, B250, CLA250, B250e, and B Electric Drive applications. Delphi applies OE-focused engineering practices to its aftermarket steering and suspension portfolio, including material verification and dimensional analysis to help maintain proper fit and function. The steel arm and natural rubber bushings are selected to support suspension articulation while helping preserve alignment stability and ride control. This part cross-references MOOG Chassis Products RK642798 for the same application.

Common Problems This Part Can Address

• Excessive rear suspension play from worn control arm bushings
• Clunking or knocking noises from the rear lower suspension area
• Uneven tire wear related to rear alignment movement
• Loose or unstable handling from a fatigued control arm
• Corrosion-related replacement needs on the rear suspension arm

Installation Notes and Tips

Confirm the rear lower forward position before ordering and compare the original arm length and bushing layout to the vehicle. Because mounting hardware is not included, reuse or replace fasteners as required by the vehicle service procedure. After installation, perform a professional wheel alignment to verify rear suspension geometry on Mercedes-Benz GLA250, B250, and CLA250 applications.

Quality Assurance

Delphi subjects this control arm to extreme-temperature testing and extended salt-spray exposure, along with OE-level dimensional and material analysis. Those validation steps help support consistent fit and durability across the listed Mercedes-Benz applications.
