SKF 16427 Transfer Case Output Shaft Seal - Front Outer

SKF 16427 Transfer Case Output Shaft Seal

SKF 16427 is a transfer case output shaft seal built for applications that need reliable fluid retention at the output shaft. With a polyacrylate sealing surface and precise dimensions, it supports a tight seal where the transfer case meets the driveline.

Compatible with Ford Bronco II, Ford Ranger, and Ford Aerostar applications using a Warner 1350 with manual shift, this SKF 16427 seal is specified for front outer positions in the listed fitments.

Key Features

• Transfer case output shaft seal for front outer applications
• Polyacrylate sealing surface type for controlled sealing performance
• Outside diameter: 2.684 in.
• Shaft diameter: 1.614 in.
• Width: 0.456 in.
• SKF engineered sealing design backed by long-running seal manufacturing experience

Application Details

SKF 16427 is used in transfer case sealing systems where the output shaft must retain lubricant and keep road contaminants out. It is listed for 1984-1990 Ford Bronco II, front outer, Warner 1350 w/ Man. Shift; 1983-1990 Ford Ranger, front outer, Warner 1350 w/ Man. Shift; and 1986-1989 Ford Aerostar, front outer, Warner 1350 w/ Man. Shift. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems 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 outer seal area
• Seal wear from age, heat, and driveline movement
• Loss of sealing integrity in Warner 1350 manual-shift setups

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the transfer case bore and output shaft. Inspect the shaft surface for grooves, corrosion, or scoring before installing SKF 16427, and clean the sealing area thoroughly so the new seal seats evenly.

Quality Assurance

SKF has a long history in seal engineering, including early integrated shaft seal development, and manufactures seals to specific designs using premium materials for the application and operating environment. SKF 16427 is produced to high quality standards for long service life and dependable sealing performance.
