Many people traveling on our roads today do not understand the importance of maintaining the suspension system of the vehicle they are driving. While they commonly think of servicing such things as the engine, the brakes and the exhaust, the suspension sometimes gets neglected.
This is not a good thing considering the suspension is the part of your vehicle that allows you to keep control of it on the roads. The suspension is made up of many different parts. General front side suspension systems come in two fundamental configurations. One of them uses front gasoline charged struts (big coil over shock absorbers), lower ball joints, suspension springs, a stabilizer or anti roll bar along with various rubber bushings and grommets to complete the system. The second type of system that is normally found has all of the above except the gas charged struts, these are replaced with smaller gas charged shocks and the addition of the upper ball joint.Visit Cardan Shaft India

Now to examine the pieces that makes up your suspension in a little more depth.
The gas charged struts on the front of the vehicle handle shock absorption. They connect to the upper inner fender nicely on a bolstered section of the vehicles main structure. Sometimes they are fitted into what is called a bearing plate on the top and connect to the wheel hub itself. The purpose of the bearing plate is to allow the strut to turn and rotate as you turn the steering wheel pointing your vehicle in the direction you want to go. Sometimes they are mounted solidly, this just means the vehicle strut does not turn when the steering wheel is turned and it is normally fastened to the lower control arm rather than the wheel hub. By absorbing the shock from the road it allows your vehicles tyres to remain in constant contact with the road surface thus allowing you full control while driving.Get more information about Suspension
The ball joints (upper or lower) possess two primary jobs. They allow the wheel hub to rotate as you turn the steering wheel and they also allow the up and down movement of the tyre when traveling on a road surface. Years ago these ball joints were what we call serviceable. This means they had grease fittings built into them in order to grease and extend the life of them. More recently most manufacturers have adopted a non serviceable design which come pre greased from the factory as a sealed unit. The downside to this design is that if the protecting rubber boot around the joint itself rips you are left with little alternative but to replace the entire ball joint itself. On some vehicles the ball joint can be removed from the lower or upper control arm and replaced on its own, on others they are a welded unit and will need to be replaced as an assembly when used.
The suspension springs support the weight of the vehicle and return it to normal ride height after the suspension can be compressed. The road springs come in two different types. One type is what is called a coil over spring. These are actually mounted on the vehicle and the front strut slides through the middle of them. So coil over means the coil is over or surrounding the actual strut. The other type is a conventional road spring set aside from where the strut is mounted on the vehicle. Both types do their intended job well. It just depends on the vehicle designers which type they choose to use in their vehicles.
The stabilizer bar or anti roll bar can be another system component with one singular job. In effect it is a sturdy singular bar that spans the front of the vehicle and is attached with what are known as stabilizer or anti roll bar links to the lower control arms of the suspension. The sole purpose of this bar is to stop the vehicle from dropping traction to the front wheels when cornering. As your vehicle goes into a turn, if it did not possess the anti roll bar, all of the weight of the vehicle would be transferred to the outside wheel causing the inside wheel to have little, if any, traction on the road.
As a combined system your suspension continues you and other motorists around you safe while your vehicle is on the road. If the system is allowed to fall into disrepair then you run the risk of not only hurting yourself but others on the road with you.
