Mine did this a while back and it was a broken vac line a good way to test it is to see if your cruise control still works or the 4X4 both are controlled by vac

So my 4x4 is ran buy a vacumn accuater or not cause my front axel has one but its welded in the locked posistion on the axel ..... And them vacumn lines are just tucked under the truck..... I think I have a problem 
I would say so, thats not doing your front diff and t-case any favors. Vac pump is below the injection pump, and the lines come up to the fire wall above the injector fuel lines. Check in that area.
