Hey all, I have a 2002 Grand Prix with about 180k on it. Recently while running down the highway i notice a feeling almost like as if the wind was gusting and blowing the car from side to side, kind of a swaying feeling from side to side. Stopped and checked wheeels and they all felt tight, kinda rocked the car from side to side to see if anything seem outa sorts, but couldn't find what was causing it. doesn't do it all the time just noticed a couple times now. really feels like it's from the back end of the car . Any thoughts on this. tried bouncing the car and shocks didn't seem to bounce much.
