1. Preparation

Gather tools and parts before beginning the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Drain Fluid

Tools Required: Socket set, fluid collection container, funnel.
Place the fluid collection container under the transfer case.
Remove the drain plug using the socket set and allow the fluid to drain completely.
Dispose of the old fluid according to local regulations.

3. Replace Seals and Gaskets

Tools Required: Socket set, torque wrench, seal puller, gasket scraper.
Remove the mounting bolts securing the transfer case to the transmission.
Carefully separate the transfer case from the transmission.
Use the seal puller to remove the old seals and gaskets from both the transfer case and transmission.
Clean the mating surfaces with a gasket scraper to ensure a good seal.
Install new seals and gaskets in their respective locations.

4. Reassemble Transfer Case

Carefully align and position the transfer case back onto the transmission.
Hand-tighten the mounting bolts to ensure proper alignment.
Use the torque wrench to tighten the bolts to the manufacturer's specified torque values.

5. Refill Transfer Case

Tools Required: Funnel.
Replace the drain plug after ensuring all seals are properly installed.
Use the funnel to refill the transfer case with the recommended fluid type until it reaches the proper level.

6. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and allow it to run for a few minutes.
Check for leaks around the transfer case and ensure all connections are secure.
