4WD Actuator motor

What is your question?

GMC Yukon 350 Yukon SLT 4wd 1999 Service 4wd light goes on. I ignore for a few weeks. Then today red light on NEUTRAL on 4wd switch comes on & Service 4wd light goes out. Now I have no 4wd. What happened? Big question I know. But could it be front actuator motor? All suspension is good, no wrecks nothing hit or rough riding did this. Truck drives fine otherwise. I do use 4wd so I will fix it. Is this the common problem? What else should I check? Help greatly appreciated. Any knowledge of replacing w/ posi-lok system?
