Description

Keep the gear oil where it belongs and dirt out of your driveline with the Schaeffler Differential Pinion Seal SS2987. It installs as a direct-fit rear differential pinion seal for a long list of GM trucks, SUVs and vans — including the 1988-1997 Chevrolet C1500, 1980-1995 Chevrolet G10, 1987-1994 Chevrolet Blazer, 1995-1997 Chevrolet Tahoe, 1992-1997 GMC Yukon and many more (see the "Vehicles it fits" section for the full 79-application list).

Job it does: seals around the pinion shaft where it enters the rear differential/axle housing, helping retain the gear lubricant and keep out dirt and moisture.
How it seats: the seal body stays stationary in the housing while its lip rides against the rotating pinion shaft.
Cataloged position: rear differential (pinion) seal.
Signs it may need replacing: gear-oil seepage or drips at the nose of the differential where the driveshaft connects. If a worn pinion seal is the cause of that leak, this replaces it — diagnose the source first, as fluid can migrate from other points.

Buyer's Q&A

Frequently Asked Questions

What does this pinion seal do?

It seals around the differential pinion shaft where it enters the rear axle housing, helping keep gear oil inside and dirt and moisture out.

Where is this seal located?

It is cataloged as a rear differential (pinion) seal, sitting at the nose of the rear differential where the driveshaft connects to the pinion.

Does the seal spin with the pinion shaft?

No. The seal body stays stationary in the housing; only its lip contacts the rotating pinion shaft.

How do I know the pinion seal needs replacing?

Gear-oil seepage or drips at the front of the differential are common signs. Confirm the leak is from the pinion seal before replacing, since fluid can travel from other points.

Does the SS2987 fit my vehicle?

It fits 79 GM applications, such as the 1988-1997 Chevrolet C1500 and 1995-1997 Chevrolet Tahoe. Check the "Vehicles it fits" section to confirm your exact year, make and model.
