Detailed Description

Delphi TC4026 is engineered as a premium suspension control arm and ball joint assembly for the front left side. Delphi applies OE-focused dimensional and material analysis to help match the original part’s fit and construction, while the assembly is tested for temperature extremes and salt-spray exposure to support durability in demanding road conditions. The stamped steel arm, black painted finish, and rubber-isolated bushings are selected for service replacement on the Ford Flex and Ford Taurus X applications listed below. If you are replacing a worn front suspension control arm on a 2009 Ford Flex or a 2008-2009 Ford Taurus X, TC4026 provides a direct replacement format with the ball joint already included.

Common Repair Reasons

• Clunking or knocking from the front suspension
• Uneven tire wear caused by worn control arm bushings or ball joint wear
• Loose or unstable steering feel at the front left corner
• Visible cracking, separation, or deterioration in the bushings
• Ball joint play affecting alignment and road control

Installation Notes

Verify position before installation: this part is listed for front left and front left lower applications depending on vehicle. Confirm mounting hole diameter, bushing dimensions, and ball joint stud style against the original component before service. Because the assembly is pre-greased and non-greaseable, no routine greasing is required after installation. An alignment check is recommended after suspension replacement.

Quality Assurance

Delphi backs this part with OE-based engineering practices, including dimensional and material validation plus environmental testing for heat and corrosion exposure. That focus helps support consistent fit and long-term service performance in the specified Ford Flex and Ford Taurus X applications.
