Application Details

This SKF 18108 seal is designed around the dimensions of the transfer case output shaft and sealing bore to help maintain proper lubricant control in the transfer case.

What It Helps Fix

  • Transfer case fluid seepage at the output shaft
  • Contamination entering the transfer case through a worn seal
  • Wet housing or driveline residue near the rear output area
  • Seal wear caused by age, heat, or mileage
  • Loss of proper lubricant retention in the transfer case

Installation Notes and Tips

  • Confirm transfer case model before ordering: New Process 231 or New Process 242, depending on vehicle application.
  • Inspect the output shaft surface and seal bore for scoring, corrosion, or debris before installation.
  • Clean the sealing area thoroughly so the new seal seats evenly.
  • Verify the seal dimensions match the shaft and housing specifications listed above.
  • Use care during installation to avoid damaging the sealing lip.
