Installation Notes
Verify vehicle year, make, model, and front lower position before installation.

Always inspect the surrounding control arm and mounting surfaces for wear or damage before installing the new ball joint.
Quality Assurance
Delphi subjects its OE-based steering and suspension parts to extreme temperature testing below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure. These validation steps support durability and corrosion resistance for demanding service conditions.
