Detailed Description

Delphi TC1663 is engineered for front lower suspension service on Ford F-250 and Ford F-350 applications listed below. Delphi applies OE-focused dimensional and material analysis to help ensure proper fit and consistent suspension geometry, while the greaseable design supports routine maintenance. The ball joint uses a press-in mounting style, a tapered threaded stud, and a protective dust boot to help manage contamination in demanding road conditions. This part cross-references MOOG Chassis Products K8435 and Mevotech Supreme MK8435 for the same application.

Fits 1997 Ford F-250 HD, front lower with 4600lb axle(s). Fits 1986-1996 Ford F-250, front lower with 4600lb axle(s) and 4.10 gear ratio. Fits 1980-1985 Ford F-250, front lower with 4500lb and 4600lb axle and 4.10 gear ratio. Fits 1982-1985 Ford F-350, front lower. Fits 1980-1981 Ford F-350, front lower with 4500lb axle(s).

What It Helps Address

• Front-end looseness or play at the lower ball joint
• Clunking or popping from worn suspension joints
• Uneven steering response caused by joint wear
• Suspension noise during turning or road impact
• Restoration of proper lower control arm articulation

Installation Notes and Tips

Install as a press-in front lower ball joint on the listed Ford F-250 and Ford F-350 applications only. Verify axle and gear-ratio notes before ordering, especially on F-250 models with 4600lb axle(s) or 4.10 gear ratio requirements. Inspect the mating control arm, steering knuckle interface, and surrounding suspension components for wear before installation. Use the included mounting hardware, nuts, and washers as specified by the service procedure, and grease the joint after installation if required by the maintenance schedule.

Quality Assurance

Delphi subjects its OE-based steering and suspension parts to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure, to evaluate durability and corrosion resistance. The brand also uses dimensional and material analysis to support OE-to-aftermarket compatibility for the listed Ford truck applications.
