4x4 not working.. front actuator works, all buttons work, tcase motor shifts high and low, no service 4x4 lights, abs light is on, think it’s hub/hubs/abs sensors.. I hear tcase make noise when I shift 2hi to 4hi, no front wheel assist... tcase shifts into low range also, is there a seperate motor to lock the 4x4 in the tcase?? Jacked truck up, tcase shifts high and low but doesn’t spin front shaft, I don’t hear any odd noises in tcase. Front actuator is work, front drive shaft and front wheels are connect when switch is pressed for 4h or 4l, and disconnected in 2h...
