replace bumpers on 2004 Chrysler Pacifica
 

My kid managed to bang up the front and rear bumper of her 2004 Chrysler Pacifica, along with a front side panel. I can find some parts at a lcoal junkyaard, but wanted to know how hard this might be to replace.
I work a little bit on my dodge ram and my harley, but dont have any power tools or air compressor.
Is it very hard to take off and install front and rear bumpers? Any step by step info any can share?
Would be greatly appreciated for any help with this. Thanks in advance.
