Common Problems This Seal Can Address

• Service replacement for a leaking transfer case seal during drivetrain repair

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the transfer case housing and input shaft dimensions. Inspect the shaft surface for wear, grooves, or corrosion before installing the new seal, since surface damage can shorten seal life. Clean the sealing bore and shaft area thoroughly so the seal seats evenly and the lip contacts the shaft correctly.

For best results, install the seal squarely and avoid damaging the sealing lip during assembly. Confirm the vehicle application by year, make, model, and transfer case configuration before ordering SKF 13963.
