Which actuator is likely not allowing my truck to shift out of 4H to 2H, the transfer case actuator or the differential actuator. I have a service 4wd light on the message center. The transfer case actuator makes a harsh buzz when actuated and the diff. Actuator sounds normal. Could it be another issue?

The one on the transfer case fails alot. You should really have it checked out by a repair shop so they can retrieve the codes from the transfer case control module.
