• Leakage caused by minor shaft wear or surface imperfections
• Heat-related seal deterioration from poor lubricant circulation

Installation Notes and Tips

Verify transfer case type and vehicle application before installation. Some listed applications note that a differential pinion race must be used with the differential pinion seal for proper installation; confirm the exact driveline configuration before service. Clean the shaft and bore thoroughly, and inspect for scoring or wear that could affect sealing performance. Use proper seal installation tools to avoid deforming the reinforced case.
