What It Helps Address

• Transfer case fluid seepage at the main shaft seal area
• Contamination entering the transfer case through a worn seal
• Leaks that can lower lubricant level in NP231-equipped drivetrains
• Seal wear from age, heat, and normal driveline operation

Installation Notes and Tips

Confirm the transfer case model and shaft dimensions before installation. Inspect the shaft surface for grooves, scoring, or corrosion, since seal condition depends on the mating surface. Clean the sealing bore thoroughly and verify the seal seats evenly during assembly. For best results, compare the removed seal to SKF 15629 and confirm the application against the vehicle and transfer case code.
