- A front axle actuator that's faulty will prevent your truck from going into four wheel drive mode. One symptom would be that the four wheel drive switch flashes when attempting to engage. Also, codes may be stored in the transfer case control module.
- How to test your actuator:
- Disconnect the wiring to it. Remove the actuator from the front axle by unscrewing it. When you reconnect the wiring and engage four wheel drive, your actuator should extend. If your actuator does not extend, and the wiring is not faulty, the most likely fault is your actuator.
