Rear Differential Pinion Seal for 1999-2015 Chevrolet Silverado 1500 & More - Schaeffler SS3085

Help keep lubricant inside the differential and road grime out with the Schaeffler Differential Pinion Seal SS3085. Cataloged for the rear position, it is a direct-fit replacement for many vehicles, among them the 1999-2015 Chevrolet Silverado 1500 and the 1999-2015 GMC Sierra 1500.

The pinion seal sits where the pinion exits the differential housing. The seal body stays stationary while its sealing lip contacts the rotating surface at the pinion. This helps hold lubricant in and keep dirt, dust and moisture out. Schaeffler works with its suppliers to design seals that meet Schaeffler's quality standards. It also notes that the seal a vehicle needs depends on the application, the position and the vehicle class.

• Contamination protection: Designed to block contaminants such as dirt, dust and moisture.
• OE expertise: Designed and built to stringent OEM standards for assured quality.
• Durable design: Backed by a robust quality-assurance process that accounts for the precise requirements of automotive systems.
• Premium materials: Chosen so the seal stays durable and effective in providing protection over time.

Signs a pinion seal may need replacing include lubricant seepage or wet residue around the pinion where the driveshaft connects, drips beneath the axle, or a low differential lubricant level. Confirm the source of the leak before replacing. See the "Vehicles it fits" section for the full list of applications and engine details.
