What to Do When the Car Makes Clunking Noises Over Bumpy Roads?
2 Answers
If your car makes clunking noises when driving over bumpy roads, it indicates that the vehicle needs to be sent for inspection and repair. As the car ages, improper maintenance can inevitably lead to unusual noises while driving, especially when passing over uneven surfaces. Clunking noises over potholes, thuds over speed bumps, and louder noises at higher speeds all suggest that the car requires inspection. Here are detailed solutions for addressing clunking noises when driving over bumpy roads: 1. Noise caused by damping failure due to shock absorber oil leakage: If the clunking noise is caused by damping failure due to shock absorber oil leakage, it is recommended to replace the shock absorber. 2. Noise caused by excessive clearance at the front fixing point of the steering knuckle: If the noise is due to excessive clearance at the front fixing point of the steering knuckle, it is advisable to remove the front fixing point of the suspension lower arm and check if the clearance is too large. If the clearance is excessive, adding shims can help offset it.
I usually do my own car repairs, and I find that clunking noises when driving over rough roads are quite common, often related to the suspension system. For example, if the shock absorbers are old and the internal fluid has leaked out, they won't absorb shocks; or if the ball joints on the control arms are loose, they can make knocking sounds when going over bumps; deformed springs or cracked rubber bushings can also produce thumping noises. I suggest you first check if the tire pressure is appropriate, as abnormal pressure can amplify unusual noises; then try a simple DIY—use a car jack to lift the vehicle and shake the wheels by hand to see if there's noticeable wobbling. For more complex issues, you'll need to visit a repair shop to inspect the chassis. Replacing shock absorbers or tightening screws usually solves the problem—don't delay, as this could lead to unstable handling and higher risks. Addressing it early can save you from spending more on serious damage later. Also, slowing down when driving over potholes can protect the parts and extend their lifespan. My experience is that regular inspections can prevent problems from worsening.
