SKF 15761 Differential Pinion Seal - Rear

SKF Rear Differential Pinion Seal

SKF Differential Pinion Seal 15761 is a rear axle sealing component built to help retain gear lubricant at the pinion shaft while keeping road debris and moisture out. It is a direct-fit style seal for service work where a worn pinion seal is causing leaks or contamination.

For rear axle repair on vehicles such as Ford F-150 and Chevrolet Silverado applications, this SKF seal is engineered around the shaft and housing dimensions needed for a proper sealing interface.

Key Features

• Part number 15761 differential pinion seal for rear axle service
• Nitrile sealing surface for dependable oil resistance in driveline use
• 1.563 shaft diameter specification for the pinion shaft interface
• 2.754 outside diameter for housing fitment
• 0.500 width profile for compact rear axle sealing applications

Product Details

SKF has a long history in seal development, including early integrated shaft seal designs and continued refinement of bonding methods and material selection. The 15761 rear differential pinion seal uses premium sealing materials selected for the demands of axle service, where lubricant retention and contamination control are critical. This makes it a practical choice for rear axle maintenance on Ford F-150 and Chevrolet Silverado driveline repairs, especially when the original seal shows wear, seepage, or hardening.

This part cross-references BBB Industries 14979 for the same application.

What It Helps Fix

• Gear oil leaking from the rear differential pinion area
• Contamination entering the axle housing through a worn seal
• Noise or driveline wear related to low lubricant level
• Seal hardening, cracking, or loss of sealing contact
• Service issues during rear axle maintenance on Ford F-150 and Chevrolet Silverado models

Installation Notes and Tips

Inspect the pinion yoke, shaft surface, and housing bore before installation. Clean all sealing surfaces thoroughly and verify the shaft diameter, outside diameter, and width match the application requirements for SKF 15761. Proper installation technique is important to avoid damaging the nitrile sealing lip and to maintain a consistent seal on the rear axle.
