The truck is a 4WD and every now and then makes a growling noise when you start from a stop, but the noise halts if you take the time to flip the drivetrain into 4WD and back to 2WD. The sound appears to be coming from the front of the vehicle.
Why is there a loud growling noise when first moving from a stop on 2003 GMC Sonoma
Have the front axle actuator checked.... sounds like it is trying to ingage 4x4.... without the command to do do!! ...Then you cycle switch.... resets it!
