need help solving death wobble issue on robin's f250

[Fix_It]

took her truck on a test run tonight all i can say wow that hurt ! hit 35 and she dang near kicked me out of the window !!

bushings are in good shape , everything tight no play in tie rods or king pins .. only thing i didnt add after the swap was the track bar is this where i messed up ! is there an adjustable link made to be able to adjust to your vehicle lift ?


thanks
