Detailed Description

SKF 25026 is a rear differential pinion seal engineered for the Dana 80 axle used in Ford F-350 Super Duty trucks from 2000 through 2005. SKF has a long history in seal design and uses application-specific materials and bonding methods to match the operating environment of driveline sealing points. This seal is intended to retain gear lubricant at the pinion area while helping block road debris and other contaminants. This part cross-references Ford 1C3Z4676AA and NS100727 for the same application.

What This Part Helps Address

• Gear oil seepage at the rear pinion area
• Contamination entering the differential through the pinion seal
• Wet housing or driveline residue around the axle yoke
• Seal wear from age, heat, and driveline movement
• Service replacement needs on Ford F-350 Super Duty rear Dana 80 axle applications

Installation Notes and Tips

Verify the axle is Dana 80 and confirm the shaft diameter, outside diameter, and width before installation. Inspect the pinion yoke and sealing surface for grooves, corrosion, or damage that could affect seal performance. Clean the housing bore and surrounding area thoroughly, and install the seal squarely to avoid distortion. Confirm proper pinion preload and check for leaks after service.

Quality Assurance

SKF seals are manufactured to defined design standards using premium materials selected for the application and operating environment. The LongLife sealing surface type supports durable sealing performance in driveline service.
