Detailed Description
Delphi TC1670 is engineered for the front lower suspension position and is a direct service part for 1995-2000 Ford Contour, 1995-2000 Mercury Mystique, and 1999-2002 Mercury Cougar applications.

This part cross-references MOOG Chassis Products K8683 for the same application.
What It Helps Address
- Excessive front-end looseness or play
- Clunking or knocking from the lower suspension area
- Uneven steering response caused by worn ball joint components

- Restoration of proper front lower joint articulation
Installation Notes and Tips
Verify the vehicle’s front lower mounting style before installation, especially on 2001 Mercury Cougar models with 4 bolt holes. Confirm bolt pattern, mounting hole quantity, and suspension position against the removed part before service. Delphi TC1670 uses a bolt-on design and includes mounting bolts and nuts; no grease fitting is provided, so service access is not required after installation.
Quality Assurance
Delphi applies OE-level engineering practices to its aftermarket steering and suspension portfolio. The part is tested for temperature extremes and corrosion resistance, and its materials are selected to support OE-style compatibility and long-term service performance.
