If the car makes a clunking sound when it is put into gear or when the gears are changed, this indicates a potential problem with the transmission. If the sound occurs when the wheel is turned, the problem is most likely with the wheel bearings. If the clunking sound increases with acceleration, a hole in the exhaust system is one possible cause. When the car makes a clunking sound followed by vibrations during braking at high speeds, have a mechanic conduct a thorough check of the braking system.
If the clunking sound is constant, this makes the cause harder to diagnose. If the sound is accompanied by a change in the alignment of the car, the axle might be bent. In addition, this is a common result of the frame of the car being damaged and rubbing up against other parts near the wheel well. Although it is a fairly uncommon cause, engine knocking can occur from putting low-grade gas in a car.Learn more about Car Parts & Maintenance
