Solution

1. Preparation

Gather tools and materials required for the repair.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to avoid electrical shorts.

2. Fluid Change

Sub-steps:
1. Remove the drain plug from the transfer case and drain the old fluid into a pan.
2. Replace the drain plug and torque to manufacturer specifications (typically around 30 lb-ft).
3. Remove the fill plug and use a fluid pump to add new transfer case fluid (refer to owner's manual for the correct type and specifications).
4. Replace the fill plug and torque to specifications.

3. Inspect and Replace Seals

Sub-steps:
1. Identify any leaks around the transfer case seals and gaskets.
2. Remove the old seals using a seal puller.
3. Clean the sealing surfaces thoroughly.
4. Apply a thin layer of gasket maker, if required, and install new seals.
5. Reassemble any components removed for access.

4. Test Transfer Case Motor

Sub-steps:
1. Disconnect the electrical connector from the transfer case motor.
2. Using a multimeter, check for voltage at the connector while engaging 4WD.
3. If no voltage is present, trace the wiring back to the control module for faults.
4. If voltage is present but the motor does not engage, replace the transfer case motor.
