Detailed Description

Delphi TC1864 is engineered as a standard replacement ball joint for the front lower position on GM full-size vans. It features a press-in design, a 16.0 mm stud thread diameter, and a tapered stud profile for proper suspension geometry. The greaseable construction and included grease fitting support routine maintenance, while the dust boot helps protect the joint from road contamination. Delphi applies OE-based dimensional and material analysis to help maintain fit and function across the listed Chevrolet Express and GMC Savana applications. This part cross-references MOOG Chassis Products K6711 for the same application.

Compatible With 2006-2024 Chevrolet Express 2500, front lower; 2003-2024 Chevrolet Express 3500, front lower; 2006-2024 GMC Savana 2500, front lower; and 2003-2024 GMC Savana 3500, front lower. It also fits 2003-2005 Chevrolet Express 2500, front lower, with 8500lb & 8600lb GVW, and 2003-2005 GMC Savana 2500, front lower, with 8500lb & 8600lb GVW.

What It Helps Address

• Front-end looseness or play from a worn lower ball joint
• Clunking or popping noises over bumps and turns
• Uneven tire wear caused by suspension joint wear
• Steering wander or reduced directional stability
• Inspection failure from excessive suspension movement

Installation Notes and Tips

TC1864 installs in the front lower suspension position using a press-in mount. Verify vehicle year, model, and GVW before installation, especially on 2003-2005 Chevrolet Express 2500 and GMC Savana 2500 applications with 8500lb or 8600lb GVW. Inspect the surrounding control arm, fasteners, and steering components for wear before pressing in the new joint. Use the included mounting hardware, nuts, and washers as specified by the service procedure.

Quality Assurance

Delphi subjects its OE-style steering and suspension parts to temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and 720 hours of salt spray. That validation supports consistent performance for TC1864 in daily service on Chevrolet Express and GMC Savana front suspension systems.
