I have a 2008 Hummer H-3. on November 3rd 2009 while driving about 30 miles an hour on a sharp left curve, there was a loud clunk in the front end and the truck pulled hard to the right making the vehicle go down into the ditch. Several week before this incident while in a parking lot making a sharp left turn( less than a mile per hour) there was a real loud clunk in the front passengers side, this happen twice including a week before the failure. When I checked under the front end I did not see anything. The vehicle was taken to the Hummer dealer but they could not tell if anything failed. Something failed! this causes me great concern because if it happened on a main highway and the vehicle went into traffic, that would not have been good. Please help me find out what went wrong as I don't think Hummer is going to help!
