Shock Absorbers: The Invisible Heroes of Comfort and Safety

Shock absorbers are an important part of a car’s suspension, which, despite their “invisibility”, play a huge role in ensuring comfort and safety while driving. They’re like small but mighty warriors, fighting off bumps and vibrations for a smooth, controlled ride.

How do shock absorbers work? Imagine a spring. If you squeeze it and release it, it will oscillate up and down until it stops. The shock absorber “damps” these vibrations, converting the energy of movement into heat. This happens thanks to a special fluid (oil) inside the shock absorber, which passes through narrow channels, creating resistance.

Why are shock absorbers needed?

• Comfort: Shock absorbers smooth out road imperfections, preventing jolts and vibrations that can cause discomfort and fatigue for passengers.
• Handling: Shock absorbers keep the tyres in constant contact with the road, improving traction and vehicle handling, especially during cornering, braking and acceleration.
• Safety: Good shock absorbers reduce braking distances, prevent skidding and reduce the risk of the vehicle rolling over.
• Vehicle safety: Shock absorbers protect other suspension elements (springs, levers, silent blocks) from premature wear.

Types of shock absorbers:

• Oil: The most common and affordable type. Well suited for city driving.
• Gas: Stiffer than oil, providing better handling at high speeds.
• Adjustable: Allows you to adjust the stiffness depending on operating conditions.

By following these tips, you can extend the life of your VW Polo’s shock absorbers and ensure a safe and comfortable ride. Although shock absorbers are considered consumables, proper care can extend their life and save you money. Here are some tips for caring for the shock absorber rear and front from VW Polo:

Regular diagnostics: Once every 20,000 km, check the shock absorbers for oil leaks, damage and wear. Pay attention to knocks, squeaks and other suspicious sounds when the suspension is operating. Carry out suspension diagnostics at a service station at least once a year. Specialists will be able to assess the condition of shock absorbers on a special stand and identify hidden problems.

Driving carefully: Avoid sudden acceleration and braking: This places additional stress on the shock absorbers. Slow down before bumps: Potholes, speed bumps and other obstacles put stress on the suspension. The lower the speed, the less load on the shock absorbers. Do not overload the vehicle: Overloading increases wear on shock absorbers and other suspension components.

Protection from external influences: Keep it clean: Regularly clean your shock absorbers to remove dirt and road salt, which can cause corrosion. Protective covers: Use special protective covers for shock absorbers to prevent dirt and moisture from entering them.

Timely replacement: Do not delay repairs. If signs of wear appear (knocks, oil leaks, deterioration in handling), do not delay replacing the shock absorbers. Driving with faulty shock absorbers is dangerous! Change in pairs: When replacing a shock absorber on one axle, it is recommended to change the second one, even if it is still in good condition. This will ensure even suspension operation.

It is important to remember: The service life of shock absorbers depends not only on mileage, but also on operating conditions and driving style. The worse the roads and the more aggressive the driving, the faster the shock absorbers wear out.
