What Causes a Clunking Noise When Going Over Bumps?

It is not normal for a car to rattle and produce clunking noises when moving. That mainly occurs in vehicles with suspension issues when they go over bumps, rough roads, potholes, and rocks. A problem like that can be frustrating and put you at risk. A vehicle's suspension is an assembly comprising of many components, and one can wonder what might be causing the clunking sound.

We've discussed some of the causes below so that the next time you hear the rattling sound; it'll quickly occur to you what might be the problem.

Worn-out Shocks and Struts

A vehicle's shocks and struts play a crucial in its performance and handling. Their primary role is to absorb vibrations and shocks when the car vibrates and bounces on a rough track. They also help keep the tire in constant contact with the road. Continuous lack of damping can cause severe wear, which leads to pronounced bouncing and rocking when the car moves. Additionally, you'll hear clunking noises when you go over bumps.

Engine Mounts Failure

Loose engine mounts mean that the motor moves and vibrates during power on and off transitions. It might not deliver as loud a sound as faulty shocks when going over bumps, but it is a matter that one needs to take seriously. Additionally, if your power steering components have a problem, you'll hear the rattling noise when driving on uneven ground. You can quickly check that by turning the steering wheel from side to side vigorously when the car is stationary.

Another potential culprit of the clunking noise is worn-out control arm mounts or rubber bushings connected to the suspension's sway bar. One practical means of checking for rubber busing wear is to press the brake pedal firmly with an idle motor, then switch gears from park to drive to reverse. Do that while pricking your ears to any noises. If you hear clunking sounds, then get the rubber bushings repaired.
