I have a 2008 Jeep Wrangler JK Unlimited with a 3.5in rough country lift drop Pittman arm track bar relocation mount and sway bar links for rear and front. I have replaced all front end ball joints, tie rod ends and track bar drag link and pitman arm joint. New steering stabilizer, tires and lower control arms. The whole front end is basically brand new and alignment done. I havent replaced the shocks yet. Problem I am having is when driving down the highway or any road that may have grooves or uneven lanes my jeep becomes hard to control. It will dart left or right when changing lanes or road uneven. Feels loose and is unpredictable. Any ideas on what could cause this and how to fix it?
