I think my truck may be stuck in 4WDhigh but how would i be able to tell? It sounds the same whether it is in or out, kinda makes a humming noise at high speeds. Will it hurt to drive it like this until i get it looked at?

Hi:
Take the car to a road with loose gravel and see if all 4 wheels spin. Also, it isn't a good idea to drive on dry pavement in 4wd.
