Front upper ball joint designed as a direct replacement for select 1995–2011 Ford, Mazda, and Mercury vehicles. This ball joint secures the control arm to the steering knuckle, allowing smooth pivoting of the suspension while maintaining proper wheel alignment and steering response. Built for durability and reliable performance, it restores worn or failed joints to factory-like function and reduces vibration, uneven tire wear, and steering play. Note: this replacement will fit many aftermarket control arms but may not be compatible with some original equipment (OE) arms — verify fitment before installation.

- Fits select 1995–2011 Ford, Mazda, and Mercury vehicles — verify application for your specific model and control arm type.
- Durable metal construction with corrosion-resistant finish for long service life.
- Restores secure connection between upper control arm and steering knuckle to reduce play and improve handling.
- Direct-replacement design for many aftermarket arms; may not fit some OE control arms — check compatibility.
