WHAT DO SHOCKS AND STRUTS DO?
At each wheel, a vehicle will have either a shock or a strut never both. A shock and a strut do the same job on a vehicle, damping the movement of the spring and stop bouncing and swaying. Although they do the same thing, shocks and struts are completely different parts.The major difference between shocks and struts is that a strut is a structural part of the vehicles suspension system but a shock is not.
Shock absorbers are basically oil pumps. Since the oil can only flow through these valves at a certain rate, the suspension movement becomes slower, smoother, and infinitely more predictable. Conventional shock absorbers do not support vehicle weight. Instead, the primary purpose of the shock absorber is to control spring and suspension movement. This is accomplished by turning the kinetic energy of suspension movement into thermal energy, or heat energy, to be dissipated through the hydraulic fluid.
A strut is a crucial part of the vehicles steering system and greatly affects alignment angles. It is, basically, a shock absorber mounted inside a coil spring. It takes the place of the upper control arm and upper ball joint used in conventional suspensions. Because of its design, a strut is lighter and takes up less space than the shock absorbers in conventional suspension systems. Struts perform two jobs: They provide a moisten function like shock absorbers, and they provide structural support for the vehicle suspension.
