Installation Notes

Verify vehicle application by year, model, and front left upper position before installation. Inspect adjacent suspension components, alignment settings, and mounting points during replacement. Because the ball joint is already installed and the assembly is pre-greased, this part is ready for suspension service once the vehicle-specific mounting procedure is followed.
