FAG SS2867 Differential Pinion Seal - Rear Center

FAG SS2867 Differential Pinion Seal

FAG SS2867 is a differential pinion seal built with a metal and spring seal design and nitrile sealing material for controlled sealing performance at the driveline. It is sized for a 2.75 in bore diameter, 2.754 in outside diameter, and 1.813 in width to match the specified application requirements.

Compatible with select Ford rear center applications, this seal is used where the pinion enters the differential housing. The FAG SS2867 helps maintain lubricant retention while keeping out dirt, dust, and moisture in demanding axle service.

Detailed Description

FAG SS2867 is engineered for axle sealing where precise dimensions matter. The metal and spring design supports consistent contact at the sealing lip, while the nitrile material is selected for sealing performance in driveline environments. This differential pinion seal is specified for select Ford Ranger, Ford Explorer, and Ford Bronco II rear center applications, including 1990-1998 Ford Ranger rear center, 1991-1994 Ford Explorer rear center, and 1990 Ford Bronco II rear center. The FAG SS2867 also cross-references Bosch 18159 for the same application.

What It Helps Address

• Gear oil seepage at the pinion area
• Contamination from road dirt and dust entering the differential
• Moisture intrusion around the axle seal interface
• Loss of lubricant from the differential housing
• Seal wear related to age, mileage, or service exposure

Installation Notes and Tips

Verify bore diameter, outside diameter, width, and axle application before installation. Clean the sealing surface and inspect the pinion yoke and housing for wear, scoring, or corrosion that could affect seal contact. Confirm the rear center position and match the vehicle year and model exactly, especially on Ford Ranger, Ford Explorer, and Ford Bronco II applications.

Quality Assurance

FAG specifies this seal using manufacturer-level dimensional requirements and works with suppliers to meet its quality standards for axle sealing applications. The design is intended to protect wheel end and driveline components from contamination while helping retain grease or lubricant over the service life of the bearing or seal assembly.
