Installation Notes and Tips

Installation of the Delphi TC3645 ball joint requires press-in mounting tools to ensure proper seating. The included mounting hardware simplifies the replacement process, but a grease gun is recommended to lubricate the joint through the grease fitting after installation. Verify compatibility with your specific Chrysler or Dodge model year before installation. Since the ball joint is not adjustable, ensure correct alignment during installation to maintain proper suspension geometry.
