I Have A Mate Here In Australia Who Has Just Bought A New 2008 Gmc 2500 Crew Cab Duramax On His First Trip Towing His Van Which Weighs Aprox 3 Tonne The Front Of The Truck Continously Bounces Up And Down He Has Air Bags Fitted To The Rear And Changing Pressures Makes No Difference Sounds Like Shockers Are They Prone To Being Faulty From Brand New
Any Ideas Much Appreciated
