Im going to be getting a 2wd 2002 Grand cherokee from a friend of my dads from work. It is almost perfect and I fell in love with it. I know I could just get a cheap doner car and pull the parts I need to change it over to 4wd. On all the forums I have seen I people have just said the big parts that they needed but can someone who has done it write up a list of all the parts that are needed to do this swap. It is a 6cyl automatic if that matters.
