Look for a damaged or broken sway link that connects the sway bar (one runs across the front of the vechicle and one runs across the back) to the area around the bottom of the shock tower. You will have to check the condition of the connecting link at each location. These usually don't last 10 years and they are inexpensive parts. They are fairly difficult to remove without applying some elbow grease or using a good rotorary cutting tool to cut into the lock nuts to remove them. I use a Dremel style rotary power tool with (here's the key) a diamond cutting wheel. These are available from Harbor Freight Tools for about $6 for a package of three or four on a card and they don't break as easy as the stone type.
