Violent death wobble at 45+ when hitting large bumps. Control arms and all bushings are new core 4x4s, as well as track bars. Brand new tires as of last Saturday with a fresh alignment. Also has new steering linkage. Wanted to get opinions on track bar/ ball joint movement. Jeeps been in and out of the shop for about a week and no one can figure it out, also yes my steering box leaks like a stuck pig. Thanks!
