Keep the front suspension tracking true with the DELPHI control arm and ball joint assembly, part number TC9021. This front right upper unit combines the control arm and integrated ball joint into one piece that locates the wheel and lets the suspension move through its travel, and it drops in as a direct-fit replacement for the 2021-2024 BMW ALPINA XB7 (see the Buyer's Guide tab for engine specifics).
Delphi applies its OE engineering to the aftermarket steering and suspension portfolio, so this control arm and ball joint assembly is built and validated to OE performance standards.
Signs the original may need replacing include clunking on acceleration or over bumps, loose or wandering steering, and uneven tire wear. If a worn front right upper arm or ball joint is the cause, this assembly replaces it.
