What It Helps Address

• Rear differential gear oil seepage at the pinion
• Contamination entering the axle housing through a worn seal
• Noise or driveline issues caused by low lubricant level
• Service replacement for aging OE-style pinion seals
• Leak repair on 9.50-inch ring gear rear axle assemblies

Installation Notes and Tips

Confirm the axle uses a 9.50-inch ring gear and verify the shaft diameter and outside diameter before installation. Inspect the pinion yoke and sealing surface for wear, since a damaged surface can shorten seal life. Clean the housing bore thoroughly and follow the vehicle service procedure for pinion preload and torque specifications during reassembly.

Quality Assurance

SKF has a long history in seal engineering, beginning with the first integrated shaft seal in 1928. The 19314 differential pinion seal is manufactured to application-specific dimensions using premium sealing materials for driveline service.
