3. Inspect and Replace Components

Sub-steps:
1. Remove any components obstructing access to the transfer case (if necessary).
2. Inspect the transfer case actuator and wiring for damage or corrosion.
3. If the actuator is faulty, disconnect it and unbolt it from the transfer case.
4. Install the new actuator in reverse order, ensuring all connections are secure.
5. Reconnect the negative battery terminal.

4. Testing

Sub-steps:
