Why Is My Car Making a Thump Noise When Driving?

Identifying an oddity in your vehicle can sometimes prove to be a daunting task, especially when the glitch is not so apparent. Inability to identify this glitch on time can lead to a more extensive and expensive repair.

However, with signs communicated to us by our cars, we can diagnose and hone in on the actual problem. In this article, we will be examining thumping sounds.

Below are common reasons why you might hear a thumping noise from your car:

Outside the Car

Bad Tires

If you hear a thumping noise when driving that appears to be coming from the wheels of your car, your tires are most likely the problem here. It is either they are irregularly worn, have a shifted belt, or need a replacement.

Uneven wear should not be treated as a minor problem because your tires won’t produce the appropriate tread and pressure necessary for safer driving. Dealing promptly with this issue can help to forestall other problems, including the risk of an accident.

Aerodynamic Interference

Part of your car’s exterior can become loose or caked in gunk over time, resulting in thumping noises. The sound is usually frequent and sporadic, growing in intensity as you gain speed and sometimes disappearing completely. The heat and dust shield are common culprits, but any part of your vehicle’s body can also be to blame.

Under the Car

Loose or Worn Suspension Components

If you are getting the thumping sound from the front end of your vehicle, then the problem is most likely due to loose or worn suspension system components. The suspension system comprises many moving parts, including the ball joint and the bushing. If any of these components are worn out, you may start to get a jagged thumping noise. To verify this, get an experienced mechanic to inspect the entirety of the system.

Warped Brake Rotors

Hearing a clanking noise from the front end of your vehicle when braking may be a sign that you have warped brake rotors. A more pronounced noise indicates that the brake pads are overdue for replacement, requiring more labor than a regular brake job. If this is your experience, it is highly advised to treat this issue as a top priority. Leaving your brakes in a compromised condition can be catastrophic and even lead to an accident.

Exhaust System

Your exhaust system might have a problem if you pick up a clanking noise beneath your car. To help identify the source of the noise, a certified mechanic will examine each system component from the tailpipe to the front, ensuring that all clamps are secure and that there’s enough space between the chassis and the clamps.

Under the Hood

Internal Engine Component

If you are getting a metallic thump, there could be a problem with your engine components’ rotating mechanism. Low motor oil level, engine calibration, or timing issues are probable causes. If you suspect an internal engine thump, get a skilled mechanic to check it out for you.

Finally

To recap, enlist the services of a qualified automobile technician to help you determine the source and cause of the thumping noise. The technician will also provide a full inspection report, including the scope and cost of any needed repairs.
