Detailed Description

This Timken transfer case output shaft seal is engineered to retain lubricant at the output shaft while helping keep contaminants out of the transfer case assembly.

What It Helps Fix

• Transfer case fluid leaking from the output shaft area
• Contamination entering the seal lip and wearing the sealing surface
• Heat-related seal deterioration from poor lubricant circulation
• Leakage caused by minor shaft or spindle imperfections
• Loose or damaged seal fit in the housing bore

Installation Notes and Tips

Confirm shaft diameter, housing bore, and width before installation to verify the seal matches the transfer case opening. Inspect the shaft surface for grooves, corrosion, or burrs that can affect sealing performance. Clean the bore and sealing surface thoroughly, and install the seal squarely to avoid distortion of the outer case or lip.
