Installation Notes

Install on the front left lower suspension position only. Verify vehicle year, model, and suspension configuration before replacement. Because the ball joint is already installed and the assembly is pre-greased, installation focuses on removing the worn unit and securing the replacement with the included mounting hardware. After installation, a professional wheel alignment is recommended to confirm suspension geometry.
