Differential Pinion Seal for 2002-2007 Chevrolet Trailblazer & More - Schaeffler SS2585

Help keep differential lubricant in and road grime out with the Schaeffler Differential Pinion Seal / Shaft Seal SS2585. It is a direct-fit replacement for many vehicles, including the 2002-2007 Chevrolet Trailblazer, 2004-2005 Chevrolet Colorado and 2004-2005 GMC Canyon; see the "Vehicles it fits" section for the full list and engine details. It is cataloged for both front and rear differential positions, depending on the application.

This seal fits the opening where the pinion shaft enters the differential housing. The seal body stays stationary while its lip rides on the rotating shaft to seal that opening. Schaeffler also lists it as a shaft seal, so you will find it under both names.

• Contamination protection: Designed to help keep dirt, dust and moisture out of the differential.
• OE expertise: Designed and built to stringent OEM standards. Schaeffler works with its suppliers to design seals that meet its own quality standards.
• 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 at protecting over time.

Signs this part may need replacing: Look for lubricant seeping or dripping at the pinion end of the differential, where the driveshaft connects, or a wet, oily housing nose. Other seals and gaskets can also leak, so diagnose the source of the leak before replacing.
