Timken 100712V Differential Pinion Seal

The Timken 100712V differential pinion seal is built for rear, rear outer, front, and front outer axle applications where lubricant retention and contamination control matter. It is a direct-fit sealing solution for a wide range of trucks and SUVs, including Nissan Frontier, Ford F-250 Super Duty, and Chevrolet Silverado 1500 applications.

Key Features

• Precision sealing design helps retain gear oil and block outside contaminants
• Reinforced outer case resists installation damage and adds durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and improve seating
• Internal contamination exclusion system helps reduce debris intrusion that can lead to leakage
• Vent holes promote lubricant flow around the seal lip to help manage heat buildup
• Dimensions: 3.169 in. outside diameter, 1.889 in. shaft diameter, 3.164 in. housing bore, 0.525 in. width

Detailed Description

Timken 100712V is a differential pinion seal engineered for axle assemblies that need dependable sealing at the pinion area. Its reinforced outer case supports a more secure installation, while the ribbed inner diameter helps create a tighter seal against minor surface imperfections. The seal’s contamination exclusion features and vented design work together to help keep lubricant where it belongs and reduce heat-related wear at the seal lip. This part cross-references National 100712V and SKF 20042A for the same application.

Compatible with a broad range of vehicles, including Nissan Frontier rear, Nissan TITAN rear, Nissan Xterra rear, Ford F-250 Super Duty front, Ford F-350 Super Duty front outer, and Chevrolet Silverado 1500 rear applications. It also serves many Dana/Spicer axle configurations found in Chevrolet Express 2500, GMC Savana 2500, Jeep Grand Cherokee, and Dodge Ram models.

Common Uses

• Rear differential oil seepage at the pinion area
• Gear oil loss from worn or hardened seal lips
• Contamination entering the axle housing through a damaged seal
• Heat-related seal wear from poor lubricant circulation
• Leak repair on Dana/Spicer and ring-gear-specific axle applications

Installation Notes

Verify shaft diameter, housing bore, and width before installation to confirm axle match. Inspect the pinion surface for grooves, corrosion, or burrs that could affect sealing performance. Clean the bore thoroughly and install the seal squarely to avoid distortion. For best results, confirm the exact axle type and position listed for your vehicle, especially on Ford Super Duty, Chevrolet Silverado, GMC Sierra, and Jeep applications with front outer or rear outer configurations.

Quality Assurance

Timken oil and grease seals are built with precision sealing geometry and durability-focused construction for drivetrain service. The 100712V follows Timken’s sealing design approach for controlled lubricant retention and contamination exclusion in axle applications.
