If the effectiveness of the shock absorber deteriorates, this is felt by a change in the nature of the ride. Rule of thumb: After replacing two worn sets of tires, stock shock absorbers are no more than 1/2 of their original efficiency. Therefore, they need to be changed.
Inaccurate "diagnosis" obtained using the rocking method when the car is parked. The car is rocked at a certain wing and suddenly released: the vibrations must be immediately extinguished. But in this way you can only find a completely released one! shock absorber failure.
A more accurate picture of the state of the shock absorber can be a special test bench. The diagram records the vibrations of the machine axis; the axis is preliminarily set into oscillatory motion. To do this, the liquid in the shock absorber must not be too cold, otherwise the measurement result will be distorted. With the help of the diagram, you can get the data by which the suitability of the shock absorber is judged.
