• Press-in mounting type for forged arm applications
• Greaseable design with grease fitting included
• Dust boot included with chloroprene rubber construction
• Ball material: alloy steel SAE 5140
• Housing material: carbon steel SAE 1040
• Stud thread diameter: 14.0 mm with 1.5 pitch
• Washers and nuts included
• Standard replacement, non-adjustable design

Detailed Description

Built for OE-style service on the front upper suspension, Delphi TC2542 is engineered for vehicles that use a forged arm ball joint application. Delphi applies dimensional and material analysis to help ensure proper compatibility between the original part and the aftermarket replacement. The result is a suspension ball joint that supports steering and suspension articulation while maintaining the intended fit for the vehicle platform.

This part cross-references MOOG Chassis Products K80272 for the same application. It is a direct-fit option for select Ford Crown Victoria, Lincoln Town Car, Mercury Grand Marquis, and Mercury Marauder models, including 2003-2011 Ford Crown Victoria front upper forged arm applications and 2003-2011 Mercury Grand Marquis front upper forged arm applications.

What It Helps Address

• Front-end looseness from worn upper ball joint wear
• Clunking or popping noises from suspension movement
• Uneven tire wear related to suspension joint play
• Steering wander caused by excess joint clearance
• Restoration of proper front suspension articulation

Installation Notes and Tips

Confirm forged arm application before ordering, since fitment is specific to front upper positions on listed vehicles. Press-in installation requires proper suspension service tools and correct alignment procedures after replacement. Verify thread size, stud type, and dust boot clearance during installation to ensure proper seating and movement.

Quality Assurance

Delphi tests this OE-style replacement through temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure. That testing, combined with OE-focused material and dimensional analysis, supports consistent performance for the listed Ford, Lincoln, and Mercury applications.
