SKF 20098 Differential Pinion Seal - Rear

SKF 20098 Differential Pinion Seal Overview

SKF 20098 is a differential pinion seal built for driveline and axle sealing applications where the pinion shaft must retain gear oil and keep road contaminants out. With a 2.000 shaft diameter, 3.194 outside diameter, and 0.469 width, this seal is sized for precise sealing performance in the differential housing.

For vehicle service work on applications such as Ford F-150 and Chevrolet Silverado driveline repairs, the SKF 20098 helps restore proper sealing at the pinion area. The nitrile sealing surface is selected for dependable contact with the shaft and consistent operation in demanding undercar conditions.

Key Features

• Differential pinion seal for driveline and axle service
• 2.000 shaft diameter for application-specific fit
• 3.194 outside diameter for housing sealing
• 0.469 width for correct seal profile
• Nitrile sealing surface for reliable oil retention
• SKF engineering and manufacturing standards for sealing components

Detailed Product Description

SKF has a long history in seal design, and the 20098 reflects that experience with a seal built to specific dimensional requirements and premium material selection. The nitrile sealing surface is used to maintain contact at the pinion shaft while helping keep lubricant inside the differential and dirt, water, and debris outside. This makes the SKF 20098 a practical choice for differential service where seal integrity matters.

This part cross-references CSF 10763 for the same application. It is also associated with replacement use on Ford F-150 and Chevrolet Silverado driveline repair jobs where the original pinion seal needs to be renewed. The SKF 20098 part number is commonly searched by technicians and parts buyers looking for a differential pinion seal with defined shaft and housing dimensions.

Common Problems This Seal Addresses

• Gear oil leaking from the differential pinion area
• Contamination entering the axle housing through a worn seal
• Noise or driveline issues caused by low lubricant level
• Seal wear from age, heat, and road exposure
• Service replacement after pinion area maintenance

Installation Notes and Tips

Inspect the pinion shaft and seal bore before installation to confirm the sealing surfaces are clean and free of scoring. Measure the shaft diameter and housing dimensions against the SKF 20098 specifications before assembly. Proper seating and alignment are important for maintaining a uniform seal contact pattern and reducing the chance of early leakage.

Quality Assurance

SKF designs and manufactures sealing products to high quality standards, using application-specific materials and construction methods developed from decades of seal engineering. The SKF 20098 is built for long service life in driveline sealing applications.
