Technical Details and Construction

The Delphi TC1671 suspension ball joint features a robust ball made from SAE 5140 alloy steel, known for its strength and wear resistance. The housing is crafted from carbon steel, providing a solid foundation for suspension components. The ball joint assembly includes a chloroprene rubber dust boot to protect internal components from dirt and moisture, extending service life. The stud is threaded with a 14 mm diameter and tapered at 0.125 inches per foot, ensuring a precise fit and secure connection. This ball joint is designed for press-in mounting and comes with essential hardware such as a castle nut, cotter pin, washers, and mounting hardware to facilitate installation.

Compatible Vehicles and Applications

This suspension ball joint is compatible with the following vehicles:

• Ford Taurus
• Lincoln Continental
• Mercury Sable

It is intended for use in standard suspension systems where a non-greasable, durable ball joint is required to maintain proper steering and suspension geometry.

Common Suspension Issues Addressed

• Eliminates excessive play or looseness in suspension linkage
• Prevents uneven tire wear caused by worn ball joints
• Reduces clunking noises during steering or over bumps
• Maintains proper wheel alignment and handling stability
• Protects suspension components from dirt and moisture ingress

Installation Notes and Tips

Installation of the Delphi TC1671 ball joint requires pressing the unit into the control arm or mounting location. Ensure the mounting surface is clean and free of debris before installation. Use the included castle nut, cotter pin, washers, and mounting hardware to secure the ball joint properly. Since this ball joint is non-greasable, no additional lubrication is necessary. Verify that the tapered stud seats correctly and that the cotter pin is installed to prevent loosening during operation.
