• Knuckle Material: This ball joint is specifically engineered for models equipped with factory steel steering knuckles. It will not fit models with aluminum knuckles.
• Press-In Type: This is a press-in style component. You will need a standard ball joint press tool to swap out the old unit and seat the new one securely.
