DRIVING SOUTH ON I65 BETWEEN GARDENDALE, AL AND BIRMINGHAM, AL. AT APPROXIMATELY 60 MPH - CLEAR DAY, SUNNY APPX 80 DEGREES AT 11:00 AM CST. CONCRETE ROADWAY WITH EXPANSION JOINTS. EXPERIENCED VIOLENT GYRATIONS - CAR LITERALLY BOUNCING OFF ROADWAY. SLOWED TO 50 MPH AND MOVED VEHICLE TO FAR LEFT LANE - ROADWAY WAS SMOOTHER AND CAR RETURNED TO A STABLE CONDITION. THE ORIGINAL LANE WAS ROUGHER. BUT THE CAR BECAME VERY UNSTABLE TO THE POINT OF FEARING THAT I WOULD LOSE CONTROL. I WAS ABLE TO RESUME NORMAL FREEWAY SPEEDS WITHOUT FURTHER INCIDENTS. NO APPARENT DAMAGE BUT I WILL HAVE THE SUSPENSION CHECKED BY THE DEALER. *TR
