Exhaust Noises, Clunks, and Creaks: What Your Car's Underside Is Trying to Tell You

‎When you drive over a bump, what is that clunk underneath the car? What makes the exhaust to suddenly rattle when you are accelerating? These sounds are never random; they can be signs of worn, damaged, or loose components beneath your vehicle.

‎At Wrights Car Care, we can help you find the root cause before it becomes serious.

‎Rattling that Becomes Louder While Driving

‎Most rattle noises under the car come from the exhaust system. Exhaust components can vibrate if the hangers are worn, the brackets are damaged, or the heat shields are loose. When accelerating, the engine movement can also make the sound more noticeable as it changes the position of the exhaust.

‎An auto repair professional can check the exhaust for loose shields, hangers, clamps, and pipes. This appropriate inspection is necessary, since tightening a single component might not solve the problem.

‎Clunks over Bumps and Uneven Road

‎A heavy clunk sound when driving over speed bumps or potholes could signal suspension issues. Plus, loose components, worn bushings, broken shocks, or other worn components can result in unnecessary movement. If a clunk occurs, make sure you note it.

‎That's not all. If a wheel goes over an uneven surface, then suspension components could be affected. Other signs to look out for are unusual tire wear or changes in the handling of the tyres. A good auto repair expert will explain whether the sound needs monitoring or attention.

‎Creaks During Turns or Body Movement

‎There may be several reasons for creaking noises. As parts age, they can cause rubber bushings to wear or dry, and suspension joints to become movable. The noise could be heard when turning your steering wheel, pulling into a driveway, or crossing over a sharp transition.

‎In some cases, these sounds may be difficult to inspect due to vibrations in the metal and may appear to be coming from a different place. An auto repair shop technician in Brookhaven might have to lift the vehicle and inspect the components for any looseness or damage.

When the Exhaust Sounds

Rattling is just one of several exhaust problems. If the pipe is broken or the muffler is damaged, it can produce a lower, deeper sound, and if sections are not tight, they could knock against the underside of the car. It is important to pay attention to changes in exhaust noise, especially if they happen suddenly.

‎Wrights Car Care can check for any visible issues that may be causing problems with the system, such as broken parts, loose connections, or misaligned components. Paying attention early ensures there's no damage to surrounding parts. Though a small noise isn't necessarily an instant breakdown, it can indicate a potential problem.‎ An auto repair shop in Sandy Springs can figure out if the sound is due to normal vibration or perhaps a mechanical issue.

‎Why Ignoring Underside Noises Can Cost More

‎Your car's underside gives off sounds that you shouldn't ignore. Loose exhaust parts can cause rattles, clunks can indicate suspension issues, and worn bushings and joints can cause creaks.

‎If your car is making odd sounds, Wrights Car Care has the experts who are ready to help you figure out the problem and also provide a viable solution. Call us today.

What Our Happy Customers Are Saying

My experience with Wrights Car Care was probably the best car repair experience I could ask for. The last thing that you want to worry about while putting yourself through college is whether or not you can trust the people working on your car.  Wrights Car Care was very honest about exactly what the problems were with my vehicle and which issues needed to be addressed immediately and which ones could wait.  I have had no issues with any of the repairs I have had. They really have the customer's best interest in mind and it shows!

Susan Knippenberg

have been going to Wright's for numerous years and David has always been honest and helpful and concerned about each customer and their circumstances.  They always give detailed reports about what needs to be fixed and even a time frame if it can wait a while or needs immediate attention.  I really appreciate that personal attention.

Marcia Werner

This place is absolute gold. We moved to the neighborhood 3 years ago, and they have been our go-to car place for every issue, large or small, ever since. It's like bringing my car to a trusted and knowledgeable family member. They have done everything from major repairs to minor tune-ups for us, and we have never been dissatisfied. Twice I have brought my car not sure what was going on, and it turned out to be a small enough issue that they fixed it on the spot for no charge! Honest, competent, quick, fair, and kind. You can't do better.

Amy Robertson

Wrights car care rocks!! I had a car issue with a quick timeline to get back to college. David got me in and out quickly, with the part I needed, and didn't try to sell me something I didn't. You cannot beat the kindness and service I experienced!! We have gone to Wrights Car Care before, and this is why we keep going back. THANK YOU!!
