Detailed Product Overview

The Suspensia X05CJ1126 suspension control arm and ball joint assembly is engineered for BMW front suspension service where OE-style fit and geometry matter. It is a direct replacement for the front right lower position on 2019-2023 BMW 330i and 330i xDrive, 2021-2023 BMW 330e and 330e xDrive, 2021-2023 BMW 430i, 2020-2023 BMW M340i, 2021-2023 BMW M440i, and 2023 BMW M240i. This part cross-references Delphi TC4390 for the same application. The forged aluminum design, pre-greased joint, and included rubber bushings support a clean suspension refresh on BMW 330i, BMW M340i, and related models.

What This Part Helps Address

• Front-end looseness from worn control arm bushings
• Clunking or knocking from a failing ball joint assembly
• Uneven tire wear caused by suspension wear
• Steering instability or wandering at the front right corner
• Restoring proper suspension alignment after component wear

Installation Notes and Tips

Install at the front right lower suspension position only on the listed BMW applications. Verify stud thread size M14 x 1.5 and wrench size 21 mm before installation. Because the assembly is pre-greased and includes bushings and a dust boot, it is suited for a direct replacement service, but final alignment should be checked after suspension work is completed.
