What This Seal Helps Address

• Differential fluid seepage at the shaft or axle sealing point
• Contamination entering the differential housing through a worn seal
• Noise or driveline wear associated with low lubricant level
• Leak-related maintenance on Ford Fiesta, Ford Focus, and Ford EcoSport driveline assemblies
• Front differential or axle seal replacement on listed Ford and Mercury vehicles

Installation Notes and Tips

Verify the seal dimensions, 40.0 mm inside diameter, 55.0 mm outside diameter, and 10.2 mm height, before installation. Inspect the shaft surface for scoring or wear, clean the sealing bore thoroughly, and confirm the radial shaft seal orientation matches the application. On vehicles such as Ford Fiesta, Ford Focus, and Ford EcoSport, confirm whether the listed position is Front or N/A before ordering.
