Suspension

How Car Suspension Works

The suspension system is a major part of the structure of any vehicle and it is made up of a complex series of components including shock absorbers, springs and linkages. The suspension system works to reduce vibrations and absorb road impact for a smooth and comfortable driving experience. It also maximises friction between the tyres and the road to provide steering stability and good handling, enabling the driver to retain control.

Without suspension to absorb the forces of the road, tyres would not be able to retain contact with the surface of the road, which is essential for handling, steering and braking. In addition, if the suspension system did not absorb forces from the road, this could cause damage to the chassis of your vehicle.

Common Suspension Faults

The suspension of a vehicle is made up of different components and so it can be difficult to locate problems. These are the most common faults which can occur with suspension systems:

  • Shock Absorbers are subject to wear and are often a common cause of suspension problems
  • Springs can snap or snag after a length of time, this is more likely if your vehicle frequently goes over speed bumps
  • The Constant Velocity Joint is covered by a protective rubber component which can wear over time. If it does break, this leaves the joint exposed to damage.
  • The Constant Velocity Joint is often worn down as it constantly moves when the vehicle is in motion
  • Track Rod Ends which help to turn the wheels are prone to wear but are simple to replace

Signs of Suspension Problems

Diagnosing problems with car suspension is difficult as some signs can often indicate an issue with a different vehicle component. Never ignore any of the following symptoms as driving on damaged suspension could cause further damage!

  • Driving is uncomfortable and you can feel bumps in the road
  • It takes longer to come to a stop when braking
  • Increased and/or uneven tyre wear
  • Vehicle pulls to either side
  • One corner of the vehicle sits lower when on level ground
  • Difficulty steering

Free Suspension Health Check

Problems with your suspension system can be difficult to identify due to gradual wear over time. We would recommend having your suspension checked every 12 months or 12,000 miles, if it is not checked during your annual car service or if you have noticed any of the signs listed above.
