Keep the front suspension tight and the steering precise with the Delphi control arm TC4026, a front left lower control arm and ball joint assembly that drops in as a direct-fit replacement for the 2009 Ford Flex and 2008-2009 Ford Taurus X — the exact 2009 Ford Flex lower control arm many owners are searching for. The arm locates the wheel and connects it to the chassis, while the integrated ball joint allows the steering and suspension to move together; see the Buyer's Guide tab for engine-level fitment.
Delphi applies its OE steering expertise to this aftermarket part, testing to the extreme — below -40°C, above 120°C, and through 720 hours of salt spray — with dimensional and material analysis for close OE compatibility.
If a worn control arm or ball joint is behind clunking over bumps, loose steering, or uneven tire wear, this assembly replaces the failed original. Interchange: 8A8Z-3C403-A
