Solution

1. Preparation

Tools Required: Socket set, torque wrench, fluid pump, drain pan, funnel, clean rags.
Parts Required: Transfer case fluid (as specified in the owner's manual).
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.

2. Drain Old Fluid

Place a drain pan underneath the transfer case.
Using a socket set, remove the drain plug from the transfer case.
Allow the old fluid to fully drain into the pan.
Inspect the drain plug for metal shavings or debris and clean if necessary.

3. Replace with New Fluid

Reinstall the drain plug and torque it to the manufacturer's specifications (consult the owner's manual for the correct torque value).
Locate the fill plug on the transfer case and remove it using the socket set.
Using a fluid pump, fill the transfer case with new fluid until it reaches the fill level (fluid should start to pour out of the fill hole).
Reinstall the fill plug and torque it to specifications.

4. Final Check

Start the vehicle and allow it to run for a few minutes.
Shift through the different drive modes (2WD, 4WD) to circulate the fluid.
Check for leaks around the drain and fill plugs.
