SKF 30153 Differential Pinion Seal - Rear

SKF 30153 Differential Pinion Seal

SKF 30153 is a differential pinion seal built for driveline sealing performance where the pinion shaft enters the axle housing. Its dual-lip construction adds a primary sealing lip and a radial lip to help block dirt and water intrusion, while the Bore-Tite outer coating helps reduce oil seepage from minor housing bore imperfections.

For drivers and technicians searching for a differential pinion seal for Ford, Chevrolet, or Chrysler axle applications, SKF 30153 provides a precise sealing solution for the pinion area. The LongLife sealing surface and 3.000 shaft diameter support consistent contact at the seal interface.

Key Features

• Dual-lip design for added sealing protection
• Bore-Tite coated outer diameter to help control leaks at the housing bore
• LongLife sealing surface type
• 3.000 shaft diameter
• 4.943 outside diameter
• 0.807 width
• SKF part number 30153 for axle and driveline service

Detailed Description

SKF 30153 is engineered as a differential pinion seal for the driveline and axle sealing system. The seal’s dual-lip layout is designed to create a stronger barrier against contamination at the pinion opening, which is critical in maintaining differential oil retention and protecting internal components. The Bore-Tite coating on the outer diameter helps compensate for small scratches or minor imperfections in the housing bore, supporting a tighter seal at the case interface. This part cross-references Chrysler 30153 and A1205H2426 for the same application.

When servicing a Ford F-150, Chevrolet Silverado, or Chrysler axle assembly, a properly sealing pinion seal helps maintain lubricant level and reduce contamination at the differential. SKF 30153 is a practical choice for technicians replacing a worn or leaking pinion seal in rear axle service.

What It Helps Fix

• Gear oil leaking from the differential pinion area
• Contamination entering the axle housing through the pinion opening
• Seepage caused by minor bore imperfections
• Seal wear from age, heat, and driveline movement
• Loss of differential lubricant around the pinion shaft

Installation Notes and Tips

Inspect the pinion yoke, seal bore, and shaft surface before installation. Clean the housing bore thoroughly and verify the shaft diameter matches the seal specification. Proper installation depth and alignment are important to avoid premature wear and repeat leaks. Confirm the axle application by part number and dimensions before service.

Quality Assurance

SKF has more than 100 years of experience in bearing and seal engineering, and this seal is manufactured to SKF quality standards for durability and safety in driveline service.
