- Summary
- Some 2021-2025 F-150 vehicles built on or before 30-Apr-2025 equipped with the 9.75" rear axle (minor feature code EGPAF) may exhibit a drive pinion seal leak. To confirm a vehicle is built with a minor feature code EGPAF, review the build information by double-clicking the vehicle identification number in the upper left-hand corner in the Professional Technician System (PTS). This may be due to the rear axle drive pinion seal. To correct this condition, replace the rear axle drive pinion seal with revised part number NL3Z-4676-A. Refer to Workshop Manual (WSM), Section 205-02. For claiming, use causal part number 4676 and labor operation 4676A.
