Know Your Suspension System

The suspension system of your car is complex and made up of many different parts. They include shock absorbers, springs, struts and ball joints, just to name a few. The suspension system on a vehicle is between the frame and the road. Its primary function is to maximize the overall performance of a vehicle as it cruises down the road. The suspension system also helps to absorb bumps in the road and provide a safe and comfortable ride.

1. What Parts Make Up the Suspension System?

The suspension system consists of the following parts (these are the only part of the suspension system that touches the ground):

  • Coil springs

The function of coil springs is to support the vehicle at its desired height, to maintain proper alignment angles and to absorb road shock transmitted through the tires and shock absorbers.

  • Shock absorbers

Shock absorbers limit overall vehicle body movement or sway. They support the springs in your car ensuring they don’t rebound on impact over rough surfaces. In this way they absorb and level out jolts to your car. They also do the job of keeping your tyres in contact with the road at all times.

  • Stabilizer links

The stabilizer links are a critical component of this system. A stabilizer link connects to both of your front wheels and enables steering. When they’re in good shape, they give you smooth, responsive steering.

Conlinks
  • Joints/bearings/bushes

Bushes act like cushions; they’re mounted on car suspension and steering joints to absorb road bumps, control the amount of movement in the joints and reduce noise and vibration.

The entire suspension system sits on top of the vehicle’s frame, which carries the weight of the vehicle.

2. What Signs Indicate a Problem with the Suspension System?

Here are some signs that indicate that your suspension system needs some attention:

  1. Continued bouncing after hitting bumps or a dipping when braking
  2. A drifting or pulling to one side when turning corners
  3. One side of the parked car sitting lower than the other side
  4. Difficult steering
  5. Unusually bumpy rides

Bouncing and “nose-diving” likely indicates worn shocks. Pulling to one side could be as simple as a soft tire or the need for a wheel alignment or it could signify that some of the suspension components are wearing out. If your car looks uneven when on level ground with one side dipping, it could mean something in the suspension system has been damaged. Steering difficulties and rough rides are indicators of suspension system issues.

1.When Do Parts of the Suspension System Need Replacement?

Like any part of your vehicle, you will eventually need to replace certain parts of your suspension system. This is especially the case with your shocks or struts. Look for any dents, rust, or other damage on the shock absorber. These are good indicators of your shock’s current condition. If your vehicle has done more than 80,000km there is a good chance your shocks may not be operating 100% anymore. It is recommended you test your vehicle’s shocks every 20,000km.

If you routinely drive on rough, bumpy roads, you may need to replace your shocks and struts sooner. If you drive on smooth surfaces only, the shocks and struts will most likely last much longer.
