Ok used 4 wheel drive for the first time today after owning the truck for almost a year now. When I took it out of 4 wheel drive with the shift on the fly i noticed that I have no power steering and my brakes are very hard to apply. I am guessing Vaccum but not sure where to look any help???

 

The power brake assist (hydro boost) , and the power steering are both pressure supplied by thepower steering pump.. No vacuum..

 

Thanks for the help I will have to see if it is doing the same this morning.
