The shock absorber is mainly used to suppress the shock and the impact from the road surface when the spring rebounds after absorbing the shock. When passing on uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will reciprocate, and the shock absorber is used to suppress the jump of this spring. If the shock absorber is too soft, the body will jump up and down. If the shock absorber is too hard, it will bring too much resistance and prevent the spring from working properly. In the process of modifying the suspension system, hard shock absorbers should be matched with hard springs, and the hardness of the spring is closely related to the weight of the vehicle, so heavier cars generally use harder shock absorbers. The device connected with the shock-inducing crankshaft is used to counteract the torsional vibration of the crankshaft (that is, the phenomenon that the crankshaft is twisted by the impact of the ignition of the cylinder). Therefore, it is better to find a professional replacement for such an important part.
The front shock absorber of Vios is usually made into an assembly with the spring. The steps and methods for removing the shock absorber are: remove the wheel, brake disc, brake pump, tie rod, upper and lower cantilever, half shaft, upper tray screw, and then together Remove the spring, shock core, and upper tray as a whole, then use a special tool to compress the spring, remove the center screw, and then take out the shock absorber core. Both the front and rear disassembly and installation methods are similar.
