Remove the drain plug from the transfer case using a socket.
Allow the old fluid to drain completely into the drain pan.
Inspect the drain plug for metal shavings or debris; clean or replace if necessary.
Reinstall the drain plug and torque to manufacturer's specifications (usually around 30 Nm).
Use a fluid pump to fill the transfer case with new fluid until it reaches the fill level (check the owner’s manual for the exact type and capacity of fluid).

3. Inspect and Repair Transfer Case Components

Tools Required: Socket set, torque wrench, multimeter (if electrical components are inspected)
Remove the transfer case from the vehicle by unbolting it from the transmission and disconnecting any electrical connectors.
Inspect internal gears, bearings, and seals for wear or damage.
Replace any damaged components as necessary, using manufacturer-specified parts.
Reassemble the transfer case and reinstall it in the vehicle, ensuring all bolts are torqued to specifications.

4. Test Drive

Reconnect the battery and start the vehicle.
