What It Helps Address

• Transfer case fluid seepage at the input shaft
• Contamination entering the transfer case through the shaft opening
• Seal wear from age, heat, and fluid exposure
• Noise or drivability concerns related to low transfer case fluid level
• Service replacement for a leaking or damaged transfer case seal

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and width before installation to verify the seal matches the transfer case opening and input shaft. Inspect the shaft surface for scoring or corrosion, and clean the sealing area thoroughly before fitting the new seal. Use proper seal installation tools to avoid distorting the lip or damaging the sealing surface. Verify the vehicle application by year, make, and model before ordering, especially on Toyota RAV4, Toyota Sienna, Toyota Venza, Toyota Matrix, Toyota Highlander, and Lexus RX350 applications.
