Take up the play in worn, clunky front suspension with the Delphi Suspension Ball Joint TC2543, a front upper ball joint that installs as a direct-fit replacement for the 2002-2005 Ford Explorer, 2003-2005 Lincoln Aviator, and 2002-2005 Mercury Mountaineer. This front upper ball joint forms the pivoting connection between the control arm and the steering knuckle, letting the suspension travel and the wheel steer while keeping everything located. If a worn joint is behind clunking over bumps, wandering steering, or uneven tire wear, replacing it addresses that failed component.
- Forged strength: manufactured with high-quality forgings for increased strength and smooth operation.
