Each motorist knows that the state of domestic roads leaves much to be desired. All this is reflected in the state of auto parts. So, the highest destructive effect is subject to machine suspension. In particular, shock absorbers suffer greatly. And here a logical question arises: whether the springs should be changed if shock absorbers fail?
It’s no secret that springs with shock absorbers work in pairs, providing smoothness and good control of the car. The task of the spring is to mitigate the blows and shocks that occur when driving through all kinds of bumps of road surface. When the wheel jumps on a bump and breaks away from the ground, the spring strives to return it to its original state. The “softer” the spring, the more energy from the blow it can absorb.
During the drive, the springs of the spring do not subside, since there is a constant “recharge” from blows on the road. Here the shock absorber comes to the aid of the spring. Its function lies in the extinguishing of the body fluctuations by converting the energy of oscillations of the suspension into heat. Since the design of the shock absorber is more complex than the design of the spring, it is a less reliable device and more often fails. With a deterioration in the quality of work, it should be replaced.
The spring also loses its properties over time, a result of which is the deterioration of the working characteristics. The spring loses its properties due to natural wear and due to fatigue of metal. In addition, the surface of the spring is damaged due to friction, full compression cycles, during the overload of the car and due to overcoming road bumps at high speed. Do not forget that there is such a phenomenon such as metal corrosion.
The springs that have failed are not able to “hold” the road, and also contribute to increased depreciation. In fact, when replacing shock absorbers, it is advisable to replace the springs. But since this is quite costly in material terms and visually determine the fatigue of the metal of the spring, not many car owners change the considered parts in the kit.
In fact, it turns out that when installing new shock absorbers in combination with old springs, it can be assumed that the service life of shock absorbers will halve twice. With the simultaneous replacement, the suspension will be completely restored. There are a number of cases when the replacement of springs is simply inevitable: the formation of visible metal corrosion, the breakdown of the spring, the visible difference in the height between the front and back of the car. If there are no visible damage to the springs, then they are allowed to change with each second replacement of shock absorbers.
In the case when the driver drives by car often alone, when replacing shock absorbers, it is recommended to change the left and right spring in places, since the left side is always more loaded due to the weight of the driver. In addition, it is important to understand that the springs (like shock absorbers) change in pairs to the axis. If this is not done, the suspension balance will be violated and the machine control will deteriorate.
