When Should I Replace My Shock Absorbers?

  • Shocks-Shocks

Shocks (and struts) are safety-critical components. Because they generally wear out gradually over time, the negative effects on safety and performance are not easily noticeable. How long they last depends on a number of factors, such as vehicle load, road and environmental conditions, as well as your driving style.

What are shock absorbers for?

In a nutshell, shock absorbers keep unwanted motion of a vehicle under control. The springs function as a cushion between the axles and the body of a vehicle, reducing vibration and shock from rough road surfaces. This can otherwise cause damage to  the underside of your vehicle.

Your car’s shocks provides a smooth ride and allows you to steer the vehicle with proper control.

What happens when shock absorbers are worn?

Shocks that begin to wear can eventually cause:

  • Uneven tyre wear
  • Loss of handling and control especially around turns and corners
  • A reduction in its road-holding force and ability to absorb road impacts, making the car bounce excessively
  • An increase in your car’s stopping distance
  • A negative effect on steering, braking, and suspension components

How do I know if I need to replace my shock absorbers?

Look out for any of these symptoms:

  1. Rough and bumpy ride – Excessive bouncing when you hit a bump
  2. Difficulty steering – Stiff or hard to turn steering wheel
  3. Abnormal steering vibration – When your steering wheel vibrates on smooth roads
  4. Handling control – Rolling, swaying, or leaning action when corning or caught in a cross wind
  5. Nose diving – Lurching forward when braking
  6. Uneven tyre wear – Pieces of rubber are gauged out of the tyre causing scalloped dips or cupping
  7. Clunking sounds – Caused when the shock bottoms out when hitting a bump
  8. Leaking fluid – Hydraulic fluid on the exterior of your shocks due to a worn seal
  9. Braking inefficiency – When tyres are not in firm contact with the ground, a longer braking distance is required before the car comes to a stop
  10. Dangerous in wet conditions – Increased risk of skidding in the wet and aquaplaning

How to check your shocks for corrosion and leakage

Any other component from your car’s suspension system could be a potential culprit causing any of the above symptoms.  If you want to check if your shock absorbers could be the problem, try the following:

  1. Check the strut mounting. Shove the car, if there is movement or noise coming from the mounting, that’s a sign of trouble.
  2. Check the housing. Is there any excess oil or notable corrosion?
  3. Look for any dents, rust, or other damage on the shock absorber.

You’re a motorist who wants to stay in control when you’re behind the wheel. All of the time. A good set of shocks will help you do that. To keep your ride safe and smooth, visit Supa Quick for a complete suspension system checkup.
