Detailed Description
Delphi TC3717 is built as a standard replacement suspension ball joint for front upper positions. Delphi applies OE dimensional and material analysis to help maintain proper fit and function, and the part is tested across extreme temperature ranges and salt-spray exposure to evaluate durability in demanding road conditions. This ball joint is a direct-fit style option for 2006-2012 Ford Fusion, 2007-2012 Lincoln MKZ, 2006-2011 Mercury Milan, 2003-2008 Mazda 6, and 2006 Lincoln Zephyr front upper applications. This part cross-references MOOG Chassis Products K500041 for the same application.
What It Helps Address
- Front-end looseness from a worn upper ball joint
- Clunking or popping noises over bumps and turns
- Uneven tire wear related to suspension joint wear
- Steering play caused by excess joint movement
- Restoring stable suspension articulation at the front upper position
Installation Notes and Tips
Fits 2006-2012 Ford Fusion, front upper; 2007-2012 Lincoln MKZ, front upper; 2006-2011 Mercury Milan, front upper; 2003-2008 Mazda 6, front upper; and 2006 Lincoln Zephyr, front upper. Verify the pressed-in mounting style, tapered stud dimensions, and non-adjustable configuration before installation. Because this is a non-greaseable ball joint, routine service is not performed through a fitting. Professional suspension service and alignment checks are recommended after replacement.
Quality Assurance
Delphi uses OE-based engineering, dimensional analysis, and material validation to support fit and durability. The part is evaluated for temperature extremes below -40 degrees C and above 120 degrees C, and for 720 hours of salt-spray exposure as part of Delphi’s testing process.
