Shock absorbers that are broken exhibit the following symptoms: 1. Shock absorber oil leakage. A normal shock absorber has a dry and clean outer surface. If there is oil leakage, it indicates that the hydraulic oil inside the shock absorber has escaped from the upper part of the piston rod, meaning the shock absorber is basically ineffective. 2. When the car passes over bumpy roads or speed bumps, a certain wheel makes a "clunking" sound, indicating that the shock absorber on that wheel has poor damping performance or has failed. 3. When the car is turning, there is a noticeable increase in body roll, and in severe cases, even skidding may occur. This is mainly because the damping force of the shock absorber is too small to effectively suppress the compression of the spring. 4. After driving on rough road conditions for a while, touch the outer shell of each shock absorber to feel its temperature. Normally, the outer shell of the shock absorber should be warm. If a certain shock absorber's outer shell is cold, it means that shock absorber is damaged. 5. When the car is stationary, press down on one corner of the car body and then release it. The body will rebound under the force of the spring. If it stabilizes quickly after rebounding, it means the shock absorber is functioning properly.

















The most obvious symptom is the loud clunking noise when going over bumps, as if sitting on a spring mattress. I experienced this when driving my uncle's car—after hitting a speed bump, the rear wheels would bounce up and down several times before stabilizing. The steering wheel also starts to feel loose, and during turns, it feels like the rear end is about to swing out. When braking, the front end dips sharply, and it's especially prone to skidding in rainy conditions. Once on the highway, when driving over undulating road surfaces, the car swayed side to side like a boat, scaring me into slowing down immediately. If you notice these symptoms, it's advisable to check the shock absorbers and also inspect whether the buffer rubber blocks have aged, as these two parts usually fail together.

I often encounter vehicles with failed shock absorbers during car repairs. The most typical symptom is irregular tire wear, such as wave-like patterns on the tread. When going over bumps, you can hear a metallic clunking sound, which indicates the shock absorber has completely lost its damping function. If you look carefully near the wheel arches, oil leakage will accumulate dust and form greasy rings. The braking distance of the vehicle will increase, especially noticeable during emergency stops. There's also a small detail: when pressing down on the four corners of the car body while stationary, a good shock absorber will rebound only once or twice, while a bad one will bounce repeatedly like a spring toy.

It's really tough for a girl when her car's shock absorbers go bad! Driving feels like riding a tractor, and passengers in the back always complain about motion sickness. My best friend's car is like this – you can see the body tilt severely in the rearview mirror when turning. On bumpy roads, lipsticks and compacts in the door storage rattle nonstop. The scariest part is overtaking trucks on the highway; the airflow makes the car sway side to side. Once while taking a curve in the rain, the wheels even briefly lifted off the ground! Later we found out the shock absorber struts had completely leaked all their oil. Remember to check the top of the shock absorbers on both sides of the trunk – oil stains will be visible if there's a leak.

Failed shock absorbers can disrupt the vehicle's geometric alignment. During straight-line driving, a longitudinal rocking motion similar to rowing occurs, especially noticeable above 80 km/h. The steering characteristics also change: severe understeer occurs when entering a turn, which suddenly transitions to oversteer mid-corner. Reduced tire contact patches lead to an increase in braking distance by over 15%. At night, the headlight beams may oscillate erratically, affecting visibility. Special caution is required when crossing railway crossings or other continuous undulating surfaces, as undamped springs can produce a resonance effect, potentially leading to a rollover in extreme cases.

The worst fear when taking kids out is having faulty shock absorbers. The formula cans roll around in the trunk, and the child safety seat wobbles over every manhole cover. A few days ago, while driving my son to school, his breakfast milk spilled all over his uniform when we went over a speed bump. Driving itself is uncomfortable too, with the seat constantly jabbing into my back. After parking, if you notice uneven wheel arch spacing (commonly called 'one leg high, one leg low'), it's a classic sign. Once, while driving my mother-in-law to buy groceries, she complained the car bounced like a lame donkey—turns out the right rear shock absorber had completely failed. It's recommended to have a mechanic perform a rebound speed test by pressing down every 20,000 kilometers.
