I have a 2007 chevy uplander, it makes a banging noise when ever i hit a bump. coil spring and shock are good but still noisy. What really is banging? Can someone please help? I love this car but just can't take the noise.
Besides exhaust system also check the evap canister it is also located up under vehicle by fuel tank jack up one side at a time and using a rubber mallet and your hands see if you can move any of the systems
Could be the exhaust system hitting the frame or body of vehicle when you hit a bump. There should be some wear marks where the pipe is hitting.
