When driving over rough roads, a vibration can be felt in the gas peddle. We have had the front end suspension parts checked and all bolts under truck tightened, including transmission mounts. We have had 4 new shocks put on. Our mechanic can not think of anything else. The chevy dealership suggested maybe ourt after market side bars are the problem. Anyone have ideas?
