One of the most important components on a vehicle is its shock absorbers, as they prevent excessive and dangerous motion of the motor vehicle and its suspension. If motor vehicles do not have shocks fitted, they would be very difficult to control on the road. Due to the bouncing that would occur, the tires will not touch the road surface and braking and trying to turn a corner will become hazardous.

To get a basic idea of how a shock works, imagine driving down a road where there are speed bumps. If the car simply has springs, but no shocks, and goes over the speed bump, the springs will continue to move back and forth until they get rid of all the power they gained when they compressed. This will cause the car to sway and bounce, once it has gone over the speed bump.

In contrast, imagine a car with both springs and shocks going over the same speed bump. In the same way, the springs would absorb the bump. The only difference is that the shocks would dampen the springs' swinging by changing the moving energy into heat, and thereby stabilizing the car's movement.

The way the shock works is that it makes use of two valves which increases the effectiveness of it. One of the valves is connected to a piston rod, which is connected to a piston. This piston sits in a tube filled with hydraulic oil. When the car wheel hits a bump in the road, this causes the spring to coil and uncoil. The energy of the spring is transferred to the shock absorber through the upper mount, down through the piston rod and into the piston.

Little holes situated in the piston lets fluids through when the piston goes down and up inside the cylinder. As the holes are so small, it only allows a limited amount of oil to pass through. This fluid is placed under pressure because of the amount it lets through. This will slow down the action of the piston and thus slow down the spring. It will then allow the assimilation of the shock from the spring's movement to go into the shock absorber.

Modern cars are fitted with speed sensitive shocks, so the more rapidly the suspension moves, the greater the forbearance the shock absorber gives. This will allow the shocks to adapt to the road conditions and regulate all the dangerous movements which can happen with a moving car. For example, brake deterioration, oscillation and bounce.

The condition of your shock absorbers should be checked when you start losing control of the vehicle upon braking and trying to enter corners. You will also feel the unevenness when you travel on uneven road surfaces or go over bumps in the road.
