Theres a rattling noise coming from the rear of the car. Any ideas what to look for?
Some, if not most, Impalas arrive with the rear exhaust hanger bolts loose or missing. Have them replaced or tightened at the dealer. Also, there is a heat shield that goes around the plastic gas tank that runs close to the exhaust. It can get resonate when a larger or noisier exhaust is installed. If the heat shield is rattling, try getting some thick sponge or that gray spongy packing material and cut it into four large pieces. Stuff the four pieces in between the heat shield and the chassis, front to rear. The pieces of sponge will act as a noise dampener. Back to the index…
