11.3. Check of shock-absorbers – is obligatory after deterioration of two complete sets of tyresIn the course of the labour activity shock-absorbers turn to «the air pump»: after deterioration of two complete sets of tyres shock-absorbers, as a rule, lose almost 50 % of the initial influence and consequently require replacement. As such decrease in their action occurs slowly and not so sharply, losses in their working capacity at once to notice difficultly. Instinctively, as well as the majority of drivers, you are accustomed to the worsened dynamic parametres of movement: in extreme situations it can lead to nasty surprises. That it does not happen, it is necessary to check annually the shock-absorbers on the test bed of the automobile club or in TÜV or DEKRA. A rocking method, when you swing the car for wings to "check up" its resonant properties, here it is obviously not enough. Such way it is possible to "expose" only completely worn out shock-absorber. But all the same pay attention to following symptoms:
Whether the steering mechanism shivers? In this case wheels "dance" by the ground or are incorrectly balanced.
Whether strongly you resounds Mondeo after movement on road potholes?
How it passes bends? Whether it is shaken on each roughness of a road cloth?
Whether uniform deterioration of tyres (partially worn out surfaces)?
Whether strong oil traces on the case of shock-absorbers are visible? Small «oil impregnations» – the phenomenon usual.

So the shock-absorber works You Mondeo will amortise wheels by means of two-tubular shock-absorbers. They consist of the working cylinder in which the working piston supplied with the valve upwards-downwards goes. The working cylinder envelops the second cylinder which forms "warehouse" for hydraulic oil.
Pressure step: the piston moves downwards and on the way squeezes out hydraulic oil through the valve in space over the piston. The valve design defines resistance occurrence (wheel amortisation) which the working piston should overcome.
Draught step: not loaded spring returns back the working piston in the starting position. The oil thus superseded over the piston through the compression valve gets back to the spare chamber. The valve defines resistance (amortisation of wheels) which the working piston should overcome.
