Installation Notes and Tips

Verify the vehicle position before installation: this part is for the front right lower forward location. Confirm fitment by year, model, and suspension configuration before ordering. Because the assembly includes a pre-installed ball joint and bushings, it is typically installed as a complete unit rather than rebuilt in service. After installation, a professional wheel alignment is recommended to restore proper suspension angles and steering performance.
