I replaced both my pitman arm and idler arm, both ball joints, and three tie-rod ends. i also replaced all of my shocks and replaced my front springs with belltech 2" drop springs. I also removed some leaves from the rear springs, shackles and a new set of tires tires. used to be pretty wild to take down the road. now it is really good, very comparable to a newer truck. my recommendation is to fix what you know is worn and go from there. You may just be happy with your handling after the bad stuff is taken out of the equation and front end replacement parts are cheap for these trucks.
