What is the solution for shock absorber bumping and clunking noises in winter?

The solution for shock absorber bumping and clunking noises in winter is: simply replace them, as this situation is caused by oil leakage or bending of the shock absorber itself. Shock absorbers are used to dampen the oscillations from the rebound of springs after absorbing shocks and impacts from the road. Shock absorbers are widely used in automobiles to accelerate the attenuation of vibrations in the frame and body, thereby improving the ride comfort of the vehicle. When driving on uneven roads, although the suspension springs can filter out road vibrations, the springs themselves still undergo reciprocating motion, and the shock absorbers are designed to suppress this spring bouncing. If the shock absorbers are too soft, the vehicle body will bounce up and down; if they are too hard, they will create excessive resistance, hindering the proper functioning of the springs.
I've noticed that the clunking noise from shock absorbers in winter is quite common, likely due to aging shock absorbers or rubber components hardening in the cold. Ignoring this can affect driving stability and the noise is really annoying. I've experienced it myself. First, check if the shock absorbers are leaking oil or have cracks—if so, they need replacing. If there's no leak, apply some low-temperature-specific grease, as regular grease tends to solidify in cold weather and won't work. Also, inspect other parts of the suspension system; loose springs can also cause noise. Try to avoid potholes when driving, and regular maintenance is crucial—check before each season change. If the problem persists, head to the repair shop promptly before the noise worsens and becomes a bigger issue.
