Service & Repair Manual

I have a knocking problem that comes from underneath the rear of the car, a 2002 Chevrolet Cavalier. Every time I accelerate, little or great, the knocking noise keeps coming, Any ideas what this could be? Thanks

Answer: If you cannot physically inspect your undercarriage by yourself, you must get your undercarriage inspected, you may have a motor mount failure or a suspension component worn out, inspect them before driving further in case there is a safety issue present.
