i have a problem with my 2006 mustang GT where when i’m cruising at like any speed and i completely let off the throttle the rear end feels like it’s swaying u back in forth, it also wobbles u in ur seat. i have a feeling its my sway bar but i’ve checked them and they look good. The rims are also beat up by the old owner with really bad dings and bends in the wheel. if anyone has a good solution please let me know.
