Rattles in front and rear end of vehicle

You know it's impossible to diagnose with absolutely no information, details, clues, hints, or observations to go on. Have the steering and suspension systems inspected at a tire and alignment shop. If you tell them nothing more than "Rattles in front and rear end of vehicle", you can be sure they're going to ask you a lot of questions rather than waste your time and money not knowing what they're supposed to be looking for.
