What we call cushions are really “cushions”. The suspension springs of a vehicle, in fact, absorb shocks and other shocks when we walk a road, squeezing and cushions and checking the amount of rebound created.
Various alarm signals are able to tell you when the cushions need to be replaced, such as the fate that the lower car parts continue to bounce after it has passed over the railroad tracks, bumps or bumps in the street. Other signals are unusual noises when you walk over the above obstacles, too much inclination of the car in narrow curves or the “dive” of the front of the car following a sudden braking.
Since all these dampen little by little, you may be used to “tired” cushions, just as you get used to longer brakes as brake pads wear out. So, you have to be careful to capture these signals.
One way to test the shock absorbers is to push hard on the bodywork at every corner of a vehicle. If the machine continues to bounce after it is let go, the shock absorbers must be replaced. However, this test may require a bit of strength, and with many SUVs and high pickups, it’s not easy to get the boost you need to do it.
In this case, a shock absorber should be checked by a specialized mechanic when the car is on a bridge, such as when the tires are rotated in a workshop. The mechanic will be able to see if there are major leaks (the cushions are full of liquid), worn out supports, or physical damage, such as dents.
Despite the advice to replace the dampers at specific intervals often given by those who sell these components – for example every 80,000 kilometers – when it is necessary to do so may depend on the vehicle and how and where to drive. If you drive often on pitched roads that put more stress on the cushions, then you will probably need to replace them more often than it is if you are driving primarily on a smooth pavement.
