i have a 2002 rodeo and am thinking about converting it to a 4wd. any thoughts of what would be the easiest and cheapest way? find a junked 4wd and strip it? go with an sas? and if so which one would fit best and be an easy convert.. kinda new to this so any info would be helpful....

Ya,,, the best way to go is sell the 2wd and buy a 4wd unless you want to get into a lot of headaches
