What’s Causing That Clunking Sound When I Go Over Bumps?

What’s Causing That Clunking Sound When I Go Over Bumps?

You’re cruising along, hit a speed bump, and clunk!—your car makes a sound that definitely wasn’t there before. It might feel like something shifted, knocked, or even bounced under the car.

At Wayside Garage, we hear this concern a lot, and the good news is: you’re not imagining things. That clunk is trying to tell you something.


🚗 Is a Clunk Over Bumps a Big Deal?

It might be. While not every noise is an emergency, clunking when you hit bumps often means there’s something loose, worn out, or broken in your suspension system—the parts that help keep your ride smooth and your tires on the road.

And when suspension parts start to fail, it doesn’t just make your car noisy—it can mess with your handling, steering, and even your braking performance.


🛞 What Could Be Causing That Clunking Noise?

Here are the most common things we find when a customer says, “My car clunks when I hit a bump”:

  • Worn Out Shocks or Struts
    These help absorb road impacts. When they’re blown, you might hear clunking and feel extra bounce after hitting a bump.

  • Broken or Loose Sway Bar Links
    These connect the left and right sides of your suspension. When they wear out, they can rattle or clunk with every dip or bump in the road.

  • Ball Joints or Control Arms
    These allow your suspension and steering to move. If they’re worn or loose, they can make a knocking or popping sound—especially over uneven roads.

  • Loose Suspension Mounts or Bushings
    These rubber parts cushion the metal suspension pieces. When they wear out or crack, metal can hit metal, creating—you guessed it—clunks.


👀 How Do I Know If It’s Serious?

Here are some signs it’s time to get your suspension checked out:

  • The clunk is getting louder or more frequent

  • Your car feels floaty, like it’s bouncing too much

  • You hear squeaks, rattles, or knocking on turns or rough roads

  • Your steering feels loose or off-center

  • You’re feeling every crack in the pavement like never before

Whether it’s a small fix or a bigger repair, the sooner we look, the better. Clunks don’t go away on their own.
