What Causes the Loud Clunking Sound When a Car Goes Over a Speed Bump?

[VanJohn]

When a car makes a loud clunking sound while going over a speed bump, it is usually caused by a loose stabilizer bar or a faulty shock absorber. This sound originates from the car's shock absorber. Here are some precautions to take when driving over speed bumps: Reduce speed in advance: When approaching a speed bump, it is best to slow down early and then pass over it straight on, distributing the impact force evenly between both tires. This balances the load on the left and right suspension systems. Avoid slamming on the brakes or accelerating; instead, let the vehicle pass over the bump naturally. This approach is both safer and helps protect the car's suspension and steering systems, minimizing potential damage. Pass over the bump with one side: When going straight over a speed bump, the car tends to bounce and jolt more significantly. However, when crossing at an angle or with only one wheel, the bouncing is reduced, and there are fewer instances of swaying when a single wheel passes over.
