What is it?

shock-absorber-suspension-whatitis_image

The suspension system of the vehicle is a complex structure that consists of several components:

  • Dampers
  • Springs
  • Wishbones
  • Wheel bearings
  • CV joints 
  • Tires

ESC

Vehicle manufacturers have developed a large number of systems to improve safety and control, including ESC (Electronic Stability Control).

When the ESC system detects that the vehicle is drifting, that the angle of body roll is too great, or that the tyres are starting to lose grip, it instantly reduces power output from the engine and applies the brakes individually with the force needed to keep the vehicle under control.​​

Slow, gradual wear
 

Slow, gradual wear<br /> 
Shock absorbers wear slowly and gradually, affecting suspension components like tyres, springs and other mechanical parts. Drivers tend to compensate for the reduced efficiency of their shock absorbers by adapting their driving style, often without noticing they are doing so. Proper vehicle maintenance, however, is essential to active safety. It is estimated that over 50% of cars on the road have worn or damaged shock absorbers. Warning! Worn shock absorbers reduce stability and roadholding, especially on bends, and also increase stopping distances. Worn shock absorbers can increase your stopping distance from 50 mph by 2 or even 3 metres.

Shock absorbers and springs: perfect partners

Shock absorbers and springs: perfect partners

Your shock absorbers and springs work together to keep your tyres in contact with the road. If your springs are worn, they can fail and cause additional stress to your shock absorbers. To ensure maximum tyre grip, always replace shock absorbers and springs together, in front and back pairs. Ask your Authorised Fiat Service Centre for advice: they will be happy to recommend the best repair solution for your needs.

A bit of history
 

A bit of history<br /> 

"Instrumental or mechanical science is the noblest and above all others the most useful, seeing that by means of it all animated bodies which have movement perform all their actions", Leonardo da Vinci.

Leonardo da Vinci discovered the principle of the ball bearing back in the 15th century, when studying friction. He understood that friction would be reduced if the balls were prevented from touching each other. He therefore developed a device to keep them apart while allowing them to rotate freely - the forerunner of the modern ball bearing cage.

The world nevertheless had to wait until the Industrial Revolution before ball bearings came into general use in industrial applications. The first ball bearing patent was proposed in 1794.

FIAT’s tips

Shock absorbers have a direct effect on:

  • Driving comfort
  • Road holding, especially on bends
  • Stopping distances
  • Tyre wear

To extend the working life of your shock absorbers:

  • Have them checked at every service
  • Always replace them in pairs, left and right
  • Replace end of travel buffers and dust cover gaiters at the same time

On average, shock absorbers should be replaced every 50 000 miles. The rate of wear, however, depends on how you use your vehicle and your driving style.

For comprehensive servicing, Mopar® Vehicle Protection offers you pre-paid service packs, for scheduled servicing as well as the replacement of the parts most subject to wear. The Mopar® Vehicle Protection servicing plans protect you against unexpected maintenance costs and possible price increases, as every plan includes a fixed discount for the duration of the plan on original used spare parts.

Self-diagnosis

To understand when your shock absorbers need replacing, take note if your vehicle develops the following anomalies:

  • Longer stopping distances
  • Reduced efficiency from the ABS and ESP systems
  • Reduced grip, and a tendency to drift on bends
  • Reduced grip in side winds and on wet roads
  • Aquaplaning, even at low speeds
  • Bouncing and suspension noise, in a straight line or when steering
  • Excessive play in the steering
  • Unusual oscillations when braking or accelerating
  • Anomalous tyre wear (uneven or rapid)

When should you replace the control arms?

  • If you hear metallic clunks when driving over bumps
  • If there is play in the rear wheels
  • If the rubber bushes are worn
As soon as you notice any of these faults, have your vehicle checked at an Authorised Fiat Service Centre.
