- Clean the mating surfaces thoroughly to ensure a proper seal.
- Install new seals or gaskets in the correct orientation.

4. Reinstall Transfer Case

Align the transfer case with the transmission and slide it back into place.
Torque the mounting bolts to the manufacturer’s specifications (typically around 25-30 Nm, but check the service manual for specifics).

5. Refill Transfer Case Fluid

Use a fluid pump to fill the transfer case with the appropriate transfer case fluid until it reaches the fill plug level.
Reinstall the fill plug and torque to the manufacturer’s specifications.
