Again: Question about Stabi + coupling rods

Hello all, I have a little bit of worries with my little flicker. It seems to me to be very windy on the side, moreover it dangles after every splint and tilts on uneven road to move. Facts: s80 MY2000, approx. 330 Tkm, FWD “normal” 215/55R16 (Conti Premium Contact) What I have already found out myself: – shock absorbers are not (Testtsnad 2 weeks ago) – track is OK (freshly measured) – “very obvious” defects could neither the nor a friend’s screwdriver see 20 tkm old I know that the first quick shot is the Stabi coupling rods – especially since I had to change one in the last 250 tkm !! What I ask myself … 1. Can also the “real” Stabis (so not the coupling rods) be covered, especially so that you can not see it at first sight? 2. What makes more sense – everything at once (all Stabis and all coupling rods) and hope that then finally some longer time is quiet, or first start small (with the coupling rods) and then, if necessary, continue with the Stabis, if that didn’t help? Thank you for your help. Andreas
