What to Do When the Rear Shock Absorber Makes Noise on Bumpy Roads?

[DeNoah]

Solutions for rear shock absorber noise on bumpy roads include: 1. Apply lubricant to the rear shock absorber; 2. Replace the shock absorber rubber bushing; 3. Install a new shock absorber. The functions of a shock absorber are: 1. To buffer the movement of the vehicle's center of gravity and conserve energy; 2. To reduce air resistance and minimize the impact of changes in the vehicle's center of gravity on the tires. The principle of a shock absorber is: When relative motion occurs between the frame and axle due to vibration, the piston inside the shock absorber moves up and down, causing the oil in the shock absorber chamber to repeatedly flow from one chamber to another through different orifices. The friction between the orifice walls and the oil, as well as the internal friction between oil molecules, creates resistance to vibration, converting the vehicle's vibration energy into heat energy of the oil, which is then absorbed by the shock absorber and dissipated into the atmosphere.
