What are suspension struts?

Suspension struts work with the shock absorbers to provide a stable, safe and comfortable driving experience. Most struts consist of a spring coil and damper and connect the axle to the car’s body. The struts are essential for delivering a comfortable ride for you and your fellow passengers.

What is the difference between struts and shocks? 

While struts and shocks form part of your vehicle’s suspension system, they are different components. Shocks are found behind the tyres, while struts are attached to each of the four wheels on your car. Struts are designed to hold the wheels in position and support your vehicle’s steering and braking systems. Shock absorbers stop the car from bouncing, particularly when driving over bumps or uneven road surfaces. 

How long do suspension struts last? 

Typically, most suspension struts can last between 50,000 and 100,000 miles. This depends on driving conditions, road quality and vehicle weight. Carrying heavy loads and driving on rough roads over time can damage your struts. Merityre’s annual car service will ensure the struts continue to provide consistent braking and steering for your vehicle. 

Top tips for maintaining your struts 

Like many parts on your car, you can maintain and extend the lifespan of your suspension struts by: 

• Installing replacement struts in pairs. 

• Avoiding potholes and driving on uneven road surfaces. 

• Maintaining the correct tyre pressure for your tyres. 

• Practising good driving habits, such as reducing your speed when turning into corners and slowing down when approaching speed humps. 

When should I replace my struts? 

There are noticeable signs which can tell you when to replace your struts, such as: 

• Your car swerves and leans while driving. 

• Knocking or clunking noises when making turns or going over speed bumps. 

• Your vehicle’s front-end nose dives while braking. 

• Excessive bouncing or jiggling. 

• There’s oil and grease on the struts. 

Will I need a wheel alignment check after replacing the struts? 

Yes, a wheel alignment check is needed once you’ve replaced worn struts with new ones. Since the struts are connected to the suspension arms and to the main body of the car, replacement struts can affect the wheel position and alignment angles. After replacing the struts, getting the wheels aligned can avoid: 

• Uneven tyre wear. 

• Reduced fuel efficiency. 

• Difficult handling. 

Understanding how the struts work with your vehicle’s suspension system is essential for having a smooth driving experience.
