Detailed Description

This Dorman suspension control arm and ball joint assembly is engineered as an OE-style replacement for the front left lower suspension on 2014-2016 Audi A3, 2016-2018 Audi A3 Sportback e-tron, 2015-2021 Volkswagen Golf, 2015-2020 Volkswagen e-Golf, 2015-2019 Volkswagen Golf SportWagen, and 2019-2025 Volkswagen Jetta. The casting/forged steel arm is paired with a ball joint already installed, helping simplify service while maintaining the original suspension geometry. Dorman part number 526-631 is also referenced by OE and aftermarket numbers including 5Q0407151J and MOOG RK622882 for the same application.

The assembly is pre-greased, includes rubber bushings, and uses a bolt-in ball joint with a threaded stud. Dorman’s evaluation process focuses on fit, ride quality, directional stability, and predictable handling characteristics, making this a practical replacement for worn front suspension components on Volkswagen Jetta, Golf, and Audi A3 platforms.

Common Problems This Part Can Address

• Clunking or knocking from the front left lower suspension
• Excessive play from a worn ball joint
• Cracked or deteriorated control arm bushings
• Uneven steering response or wandering caused by suspension wear
• Front-end vibration or instability from a fatigued control arm assembly

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front left lower position before installation. This assembly is non-adjustable and should be installed with the suspension aligned to OE specifications after replacement. Because the ball joint is already installed, inspect the mating knuckle, fasteners, and surrounding suspension components for wear before reassembly. This part is a strong match for owners searching for a front left lower control arm for Volkswagen Jetta 2019-2025, Volkswagen Golf 2015-2021, or Audi A3 2014-2016 applications.

Dorman designs this replacement control arm and ball joint assembly to meet the needs of specific OE applications and validates it through an industry-focused evaluation process aimed at consistent ride and handling performance.
