^^^ same here, definitely check your trailing arms and panhard bar. Whiteline makes a kit for all of them, very cheap and easy fix. The captive bushings in the lower arms were a bit of a pain but Timmy has a video on pressing them out (personally I just used a hacksaw and cut/hammered them out). Uppers and panhard were dead easy as they were plain old rubber, no captive steel sleeve frozen to the socket. IMO if I could go back in time and do the job over again I'd also take the time to tap all these arms and install some grease fittings for the bushings too, just an idea
