Detailed Description

This SKF 18741 differential pinion seal is made for rear axle service where the pinion shaft passes through the differential housing. SKF has a long history in seal design and uses controlled manufacturing methods to produce seals with the correct material properties for the operating environment. For vehicles such as the Ford E-150, Ford E-250, Ford E-350 Super Duty, Chevrolet Express 2500, Chevrolet Express 3500, and GMC Savana 2500 or Savana 3500, the correct rear pinion seal helps maintain lubricant inside the axle and keep road contaminants out.

This part cross-references Bremi 50637 for the same application.

What It Helps Address

• Rear differential gear oil seepage at the pinion shaft
• Contamination entering the axle housing through a worn seal
• Noise or wear concerns caused by low lubricant level
• Service replacement for aging rear axle sealing surfaces
• Leak repair on Dana 60 and Spicer M60 axle applications listed in fitment

Installation Notes and Tips

• Confirm axle configuration, ring gear size, and notes before ordering; fitment includes rear applications with 9.75 in., 10.5 in., 11.50 in., and Dana 60 or Spicer M60 references.
• Inspect the pinion yoke and sealing surface for grooves or corrosion before installation.
• Clean the housing bore and mating surfaces thoroughly to support proper seal seating.
