I just bought a new 2003 chevy silverado ext. cab shortbed. I was driving on the interstate and the road changed to concrete. Speed was 70 mph. The truck started bouncing very hard and high. So hard and high that I had a hard time keeping control of the truck. I immediately slowed down and and it still bounced hard and high. I can't take it to the dealer until Mon.. I'm by no means a mechanic. Can anyone give me a clue as to what could be wrong? Thanks.
