Detailed Description

SKF 15972 is a transfer case output shaft seal for Ford applications using the Warner 1350 manual-shift transfer case. It is designed for the front inner sealing location on the Ranger, Bronco II, and Aerostar, where maintaining a clean, stable seal is important for transfer case operation. SKF has a long history in shaft seal design, and this part reflects that focus with materials selected for the demands of the application and operating environment.

This part number, 15972, is a practical replacement choice when servicing a leaking or worn transfer case seal on a Ford Ranger, Ford Bronco II, or Ford Aerostar with the specified transfer case configuration.

What It Helps Address

• Transfer case fluid seepage at the output shaft
• Contamination entering the transfer case through a worn seal
• Wet housing or residue around the front inner seal area
• Seal wear from age, heat, and drivetrain use
• Service needs on Warner 1350 manual-shift transfer case setups

Installation Notes and Tips

Verify the transfer case model and front inner seal location before installation. Inspect the shaft surface for wear, scoring, or corrosion, since seal performance depends on a smooth sealing surface. Clean the bore and surrounding area thoroughly, and confirm the replacement seal is seated squarely to avoid leaks after service.

Quality Assurance

SKF manufactures seals to high quality standards and uses premium materials selected for the application and its operating environment. The brand’s seal engineering heritage dates back to the first integrated shaft seal design in 1928, and SKF seals have been used for decades to retain lubricants and exclude contaminants.
