Detailed Description

Delphi TC7803 is engineered as a front lower suspension ball joint for Ford E-150 and Ford E-150 Club Wagon models listed above. The assembly includes a dust boot, castle nut, cotter pin, cotter pin hole, and mounting hardware, helping support a complete service replacement. Its steel construction and press-in design match common OE service requirements, while the threaded tapered stud supports secure suspension connection. Delphi’s OE testing includes exposure to temperatures below -40 degrees C and above 120 degrees C, plus 720 hours of salt spray, along with dimensional and material analysis for OE-to-aftermarket fit alignment. This part cross-references MOOG Chassis Products K80195 for the same application.

Common Repair Uses

• Restores worn front lower ball joint movement
• Addresses looseness or play in the front suspension
• Helps correct clunking or popping from the lower control arm area
• Supports tighter steering response on Ford E-150 and E-150 Club Wagon models
• Replaces a damaged or corroded press-in ball joint

Installation Notes

TC7803 uses a press-in mounting style, so proper suspension service tools are required for removal and installation. Inspect the lower control arm, related bushings, and steering components before assembly, and verify the tapered stud, cotter pin hole, and castle nut are seated correctly during installation. Confirm vehicle application by year, model, and front lower position before service.
