What is the general lifespan of shock absorbers?

Currently, there is no specific time frame for the lifespan of shock absorbers, but they generally need to be replaced after driving approximately 100,000 kilometers. The car shock absorber is a crucial component of the vehicle's vibration filtering system. It absorbs the vibrations and impacts caused by uneven road surfaces during driving, providing a comfortable ride for passengers. Once the shock absorber is damaged, the vehicle may experience excessive bouncing and instability while driving, which can severely affect driving safety in serious cases. From the perspective of damping materials, shock absorbers are mainly divided into hydraulic and pneumatic types, with another type being variable damping shock absorbers.
Having driven for nearly thirty years, I've learned that shock absorber lifespan is really unpredictable. Generally, you should start paying attention after seven or eight years or around 80,000 to 90,000 kilometers, depending on your driving habits. When I was younger and drove long distances frequently on rough roads, my car would feel noticeably bumpy after about four years; after switching to urban commuting, they could last a decade without issues. The key is regular checks: every 10,000 to 20,000 kilometers, press down on the front of your parked car to see how quickly it rebounds—be alert if there's oil leakage or squeaking sounds. Ignoring these signs not only makes the ride uncomfortably shaky but also causes vague steering during high-speed turns and dangerously extends braking distance. I recommend getting a professional inspection every two to three years, and when replacing, don't skimp—change them in pairs to maintain balance. Avoid overloading and drive slowly on bad roads to help them last longer.
Having worked in auto repair for nearly twenty years, I've seen plenty of common shock absorber issues. Typically, their lifespan is around seven to ten years or 100,000 kilometers, though this varies in practice. For instance, vehicles frequently driven on rural dirt roads might need replacements in as little as five years, while city-driven cars can last longer. Clear signs of aging include oil leaks, excessive body bouncing, and unusual noises—all indicators it's time for a change. Remember to always replace them in pairs; changing just one can lead to imbalanced driving and suspension damage. Maintenance tip: Check for oil leakage every 10,000 to 20,000 kilometers and avoid sudden acceleration or braking. In terms of quality, OEM brands tend to be more durable despite the higher cost, reducing the hassle of repeat repairs. Delaying repairs isn't just uncomfortable due to the bouncing—it also accelerates tire wear, increasing expenses. Safety first—don't cut corners.
