Hello Impala Brothers,
My car has a knocking sound that is coming from the rear of my car. I thought it might of been the right side exhaust pipe that was hitting the spring or something everytime I hit a bump. I have some new springs and shocks that I put on some 10,000 miles. Today I went under the car and had my brother push on the car to simulate the rear end of the car hitting a bump. I didn't find any objects that were hitting against anything else. Could it be the control arms or could one of my shock(Bilstien) be defective? What do you guys think might be causing the problem?
