Detailed Product Overview

SKF has a long history in seal engineering, and this differential pinion seal reflects that experience with application-specific construction and material selection. The 14946 is intended for front differential service where the pinion area must maintain a stable seal under driveline load, heat, and exposure to lubricant. It is a direct-fit style seal for vehicles such as Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Chevrolet Trailblazer EXT, GMC Envoy XL, GMC Envoy XUV, and Oldsmobile Bravada.

Use SKF 14946 when servicing the front differential on 2002-2009 Chevrolet Trailblazer, front; 2002-2009 GMC Envoy, front; 2004-2007 Buick Rainier, front with 7.25" ring gear; 2002-2006 Chevrolet Trailblazer EXT, front; 2002-2006 GMC Envoy XL, front; 2004-2005 GMC Envoy XUV, front; and 2002-2004 Oldsmobile Bravada, front. The part number 14946 is also a useful reference when verifying replacement seals during driveline repair.

Common Problems This Seal Can Address

• Gear oil seepage at the front differential pinion area
• Contamination entering the differential through a worn seal
• Noise or driveline wear associated with low lubricant level
• Seal replacement during front differential service
• Leak repair on Chevrolet Trailblazer and GMC Envoy front axle assemblies

Installation Notes and Tips

Inspect the pinion shaft surface, seal bore, and surrounding components before installation. Clean the sealing area thoroughly and verify the shaft diameter and outside diameter match the application dimensions. During service on Chevrolet Trailblazer, GMC Envoy, and related models, confirm the front differential configuration and ring gear specification where noted, especially on the 2004-2007 Buick Rainier with 7.25" ring gear.
