Installation Notes and Tips

Verify axle identification, gear ratio, and reverse-rotation requirements before installation. This front differential ring and pinion is listed without an installation kit, so setup components must be sourced separately as needed. Proper gear setup, backlash, and bearing preload are critical for long-term operation, especially on Ford Excursion, Ford F-250 Super Duty, and Ford F-350 front axle applications.

Quality Assurance

Dorman lists this part as a standard replacement component engineered to directly replace the original equipment on specific vehicle years, makes, and models. Part number 697-455 is intended for accurate fitment in confirmed Dana 50 front axle applications.
