Detailed Description

Delphi TC1704 is engineered for front upper suspension service where accurate fit and stable joint movement matter. Delphi applies OE-level dimensional and material analysis to its aftermarket steering and suspension portfolio, and this ball joint is tested across extreme temperature ranges and salt-spray exposure to reflect demanding real-world conditions. The result is a direct replacement option for 1995-2002 Ford Crown Victoria, 1995-2002 Lincoln Town Car, and 1995-2002 Mercury Grand Marquis front upper applications. Delphi TC1704 uses an alloy steel ball and carbon steel housing, with a protective dust boot to help shield the joint from road contamination.

Common Problems This Part Can Address

• Front suspension looseness or play at the upper control arm connection
• Clunking or knocking noises from the front suspension
• Uneven tire wear related to worn suspension geometry
• Steering wander or reduced front-end stability
• Inspection failure caused by excessive ball joint wear

Installation Notes and Tips

Confirm the vehicle is equipped with the front upper application before ordering. This part uses a bolt-on mounting design with two mounting holes, included nuts, and included mounting bolts; verify bolt length, thread pitch, and mounting-hole spacing against the original component during installation. Because the joint is non-greaseable, it is installed as a sealed replacement unit. Always inspect the surrounding control arm, fasteners, and alignment settings when replacing a worn ball joint on a Ford Crown Victoria, Lincoln Town Car, or Mercury Grand Marquis.

Quality Assurance

Delphi backs this suspension ball joint with OE-focused engineering practices, including dimensional and material validation for aftermarket fitment. The part is also subjected to temperature and corrosion testing to help verify durability in service.
