All of what the previous posters suggested checking are good tips and can identify problem areas that could worsen your ride. However, you have to remember that these vehicles have a suspension setup (Torsion bars on the front and leaf springs on the rear) that is not condusive for a smooth ride regardless if you have no problems. Mine has new tires, fairly new shocks and a solid front supension, but it still has a somewhat rough ride. The new shocks and tires did help though. My wifes 2008 Ex, which has a more car-like supension, rides soooo much better.
