CAR Coil Springs / Suspension Springs

Suspension spring: common defects and their signs

  1. Stiffness reduction.
    • The car spontaneously changes its trajectory during driving.
    • Hits on the car body are felt when running over obstacles.
    • Road clearance of the wheels on one axle or on one side is different.
    • The car body inclines forward at sharp braking.
    • The tyres wear out unevenly.
  2. Corrosion or mechanical damages.
    • Abnormal knocking sound appears during driving.
    • The car rolls at cornering.
    • Road clearance decreased.
    • Car steerability worsened.
    • The braking path increased.

How to replace suspension spring?

In case of suspension spring breakdown it is to be replaced. Remember that the components should be replaced on both sides of the car for their further correct work. That is why it is recommended to buy the suspension spring kit and perform replacement in pairs. Installation of a new component is usually performed like this:

  1. Unscrew the shock absorber rod nut in the engine compartment.
  2. Loosen wheel fastening bolts, lift the car body with the help of a lifting screw, unscrew the fasteners and demount the wheel.
  3. Disconnect brake hoses from the shock strut, unscrew the bolts which fix the strut to the brake caliper.
  4. The shock absorber is demounted from its mounting seat.
  5. The defective spring is demounted with the help of a special remover and a new one is installed into its place.

As replacement requires availability of special tools for spring demounting and mandatory adjustment of the wheels alignment, it should be performed at a service station.

Replace the suspension springs as a set for each car axle.
For the safe and convenient replacement procedure use a special tool to tighten the springs.
It is recommended to leave suspension spring replacement to garage technicians.

Types:

  1. By degree of stiffness:
    • standard;
    • reinforced;
    • variable stiffness.
  2. By purpose:
    • raising springs;
    • lowering springs.
  3. By axle-related location:
    • front-axle springs;
    • rear-axle springs.

Coil Springs / Suspension Springs Information

Unfortunately, for easy and comfortable driving tires are not enough. More energy and elastic elements are required. For passenger cars there are used cylindrical coiled springs. Over time springs wear or break down. Continuous service of suspension springs often leads to subsidence of the metal. In this case power consumption and suspension travel are reduced. The suspension starts to work to the limit. This results in breakage of body parts. But even these reasons are not enough for drivers to replace worn-out or broken suspension springs. They try to put gaskets under the spring or something like that.

But because of this decision the suspension can trigger before closing of the coils springs and, as a result, the transfer of hard blows directly on the body occurs. In a correct design suspension makes full travel all the way to soft polyurethane bump stop, which immediately puts out the remnants of energy. Gasket fills air gaps between the coils of the spring and limits suspension travel, thus transforming it from a spring into a rubber one.

Both front and rear springs implement important functions. They mitigate the motion of the vehicle, prevent lateral forces, as well as provide stability of the road clearance. To make the car look sportier, there are used front springs with lowering. They can reduce the roll of the car, increase its stability and control on the road. More rigid front spring reduces turnability of the car, but it becomes more controllable. You have to realize that driving on a reloaded car is very dangerous.

If you want your car to serve you long, it is necessary to replace old springs with new that correspond to your car model.
