Why does the shock absorber make abnormal noise when passing a pit at 70 mph?

[McMaggie]

70 mph over a pit shock absorber abnormal noise is mainly caused by not slowing down when passing some large potholes. The following is the relevant introduction about driving on uneven roads: 1. Driver's posture: When driving on uneven roads, the driver should maintain the correct driving posture, with the upper body close to the backrest and both hands holding the steering wheel, trying not to let the upper body swing or jump. If the body loses stability due to the jumping of the car body, it will affect uniform acceleration and thus lose control of the vehicle. 2. Road driving method: When passing short and slightly undulating roads, you can use neutral gear to coast through. On continuous small undulating roads, you can maintain an appropriate speed and drive at a constant speed, and try to choose relatively flat ground to pass slowly.

I've been driving for several years and have encountered the issue of suspension noise when hitting potholes at 70 km/h multiple times. To be honest, this usually indicates a problem with the suspension system, such as leaked shock absorber fluid or stuck pistons, which can cause creaking sounds during high-speed impacts. It could also be due to worn suspension bushings or loose ball joints, making the noise more noticeable when going over bumps. My advice is not to ignore it - get it checked at a repair shop promptly. Replacing the faulty components will solve the problem, otherwise driving at high speeds with unstable chassis can be dangerous. During regular maintenance, pay extra attention to the suspension condition, especially for vehicles over five or six years old as parts are more prone to wear. Addressing issues early saves money and gives peace of mind.

In the workshop, we often encounter car owners complaining about shock absorber noises when going over bumps at 70 km/h. Through diagnosis, I found that most cases are due to shock absorber failures, such as seal wear or damping failure, which cause internal vibrations and noises when hitting bumps. Additionally, loose suspension links or control arms can also trigger similar noises. At high speeds, the increased impact force amplifies these issues due to higher vibration frequencies. I recommend avoiding high speeds initially, checking tires and chassis fasteners. If the noises occur too frequently, it’s best to use professional tools to test shock absorber performance to ensure overall driving safety.

My car's suspension keeps making noises recently when going over potholes at 70 km/h, which is quite annoying. A friend suggested it might be due to worn shock absorbers or weakened springs, with the impact force at higher speeds making the noise more pronounced. I need to find time to visit a repair shop, as it could be dangerous if any suspension components come loose. For now, I'm trying to avoid potholes and pay more attention to road conditions for safety.
