Do I have to replace the entire set if one shock absorber is broken?
2 Answers
For safety and long-term considerations, it is recommended to replace the entire set if one shock absorber is damaged. Here are the relevant explanations: Explanation 1: If only one damaged shock absorber is replaced, the damping force will differ between the two sides. During braking, the driver may feel uneven height and experience shaking issues, which could potentially lead to other malfunctions. Explanation 2: Shock absorbers can be primarily categorized by their damping materials into hydraulic and pneumatic types, with another type being variable-damping shock absorbers. The main function of shock absorbers is to suppress the oscillation from spring rebound after absorbing shocks and to mitigate impacts from road surfaces.
One of the shock absorbers is broken. After driving for so many years, I've learned that safety should never be taken lightly. If the shock absorbers are unbalanced, the car will experience severe body roll when cornering or on bumpy roads, especially on highways where it's prone to losing control. The braking distance may also increase, making it even more dangerous in rainy conditions. Although replacing just one might be cheaper, I recommend replacing them in pairs because the old one is likely worn out and nearing the end of its lifespan. Otherwise, you'll have to go through the hassle again when the other one fails. During regular maintenance, make sure to check the suspension system to prevent damage to other components, such as uneven tire wear. In short, peace of mind and safety should always come first.
