Modern cars, thanks to the achievements of science in the automotive industry, have become the epitome of perfection. Even inexpensive, budget cars boast enviable performance that even five years ago was shown by the best sports cars or executive class sedans.
Over time, the device of the car has changed, its technical characteristics, behavior on the road, as well as the atmosphere in the interior itself have changed. Previously, cars competed in power, speed, but now the disputes have shifted to environmental friendliness, efficiency, comfort and smoothness. Therefore, the design solutions had to be changed, and the suspension device also changed with them, since it is she who is called upon to be responsible for this indicator.
If the suspension is set too hard, it will perform well on a twisty road, as roll is minimal. No wonder racing and track cars have a very stiff suspension. But for road versions, it is not applicable, especially for our roads. First of all, it is accompanied by low ground clearance, which is simply unacceptable in our road conditions. In addition, you also need to “swallow” the bumps, which are enough.
The front suspension used to have separate springs and shock absorbers, but now they are combined into racks, it was called MacPherson strut. It has fairly stable characteristics, easy to assemble and dismantle. In addition, the manufacturer himself can choose the optimal ratio of spring and shock absorber, depending on the purpose of the rack.
Rear suspension may vary. This may be a cross beam on which leaf springs are fixed. They are sheets of metal that have a rounded shape. Under pressure, they unbend, after which they take their shape. This type of rear suspension is used on drive axles, as a rule, these are large-class sedans, as well as pickup trucks on a loading platform and trucks.
There is a rear suspension with springs. Here they are installed in glasses instead of springs. The springs have the usual helical configuration. Shock absorbers are attached separately. Such a suspension has become widespread on mid-range sedans for everyday use. Again, it is used with a leading motor or a beam. Its name is semi-independent.
And finally, the last type is an independent rear suspension. This means that the wheels of the rear axle are not fastened in any way and can move independently of each other. It is quite convenient, but difficult to install, has a low load capacity. In addition, it uses only springs, which makes it softer. As a rule, it serves for smallhatchbacks.
The rear suspension device directly affects the smoothness of the car. Here, her action will be noticed more by the passengers of the second row, because it is they who are sitting just above her. In addition, do not forget that the performance of the suspension depends not only on its design, but also on the condition, so you should not demand high results from it with worn rubber seals or leaking shock absorbers.

Knock in the rear suspension: causes and solutions
Structurally, the rear suspension of the car is much simpler than the front. However, this does not mean at all that there is nothing to knock on there. Knocking in the rear suspension usually becomes audible at the moment when repair is required. In the front chassis, you can feel the impact on the steering wheel, pedals, body, and the sounds are closer. In the rear, the sounds are reverberated into the trunk, from where it is difficult to hear them
