What Causes the Abnormal Noise When a Car Goes Over Speed Bumps?

[DeMaximus]

There are many reasons for abnormal noise when a car goes over speed bumps, mainly including faulty car shock absorbers, detached exhaust pipes, or improperly installed brake pads. Faulty Car Shock Absorbers: When the bearings of the car shock absorbers have issues, significant abnormal noise will occur when the vehicle passes over bumpy roads. In this case, it is necessary to go to a repair shop or 4S store for professional inspection and repair. Detached Exhaust Pipe: If the car has been used for a long time, the exhaust pipe may detach due to aging. When the car goes over speed bumps, the exhaust pipe area will produce a "clanging" noise. The solution to this problem is simple—just re-secure the exhaust pipe. Improperly Installed Brake Pads: If the car's brake pads are excessively worn or improperly installed, abnormal noise will also occur while driving. In this case, check the wear condition of the brake pads and reinstall them. If necessary, the brake pads can be directly replaced.
