If your vehicle keeps bouncing after you sharply press down and release on the bodywork over a wheel, it means that your shock absorbers are worn out or damaged. Shock absorbers, also called dampers, are designed to dampen the up- and-down oscillations of the vehicle's suspension. When they are worn, they cannot effectively control these oscillations, causing the vehicle to continue bouncing for some time after being pushed down. This condition compromises vehicle stability, handling, and safety, increasing stopping distances and reducing control especially on corners or bends. It is important to have worn shock absorbers checked and replaced promptly by a qualified mechanic to maintain safe driving conditions.
