Detailed Description

Delphi TC1664 is built for front upper suspension service and is engineered to match OE dimensional and material requirements for proper fit and function. Delphi applies OE-focused testing to aftermarket steering and suspension parts, including exposure to extreme temperatures and salt spray, to evaluate durability in demanding conditions. This part cross-references MOOG Chassis Products K8560T and Mevotech Supreme MK8560T for the same application. It is a direct-fit suspension ball joint for 1989-1997 Ford Ranger, 1991-1994 Ford Explorer, 1989-1990 Ford Bronco II, 1994-1997 Mazda B2300, 1994-1997 Mazda B3000, 1994-1997 Mazda B4000, and 1992-1994 Mazda Navajo front upper positions. The Delphi TC1664 is a practical choice when replacing worn front upper ball joints on these platforms.

Common Repair Symptoms

• Front-end clunking or popping over bumps
• Excessive steering play or looseness
• Uneven tire wear caused by suspension wear
• Suspension noise during turning or braking
• Visible play or wear at the upper ball joint

Installation Notes

Verify vehicle year, make, model, and front upper position before installation. Inspect related suspension components, including control arms, bushings, and fasteners, for wear before reassembly. Use the included grease fitting to service the joint according to maintenance intervals, and torque all mounting hardware to the vehicle manufacturer’s specifications.

Quality Assurance

Delphi uses OE-based dimensional and material analysis to improve part-to-part compatibility with the original component. The part is tested for temperature extremes below -40 degrees C and above 120 degrees C, and for 720 hours of salt spray exposure to evaluate corrosion resistance and durability.
