What are the symptoms of bad struts?
Struts are an essential component of a vehicle's suspension system, responsible for absorbing shocks and providing a smooth ride. However, when struts start to wear down, they can cause a range of noticeable symptoms that indicate the need for replacement. In this article, we'll explore the common signs of bad struts and what they mean for your vehicle's performance and safety.
Bouncy or Unstable Ride
One of the most obvious signs of bad struts is a bouncy or unstable ride. When the struts are worn out, they can no longer effectively absorb the impact of bumps and potholes, causing the vehicle to bounce excessively. This can make the ride feel unsteady and uncomfortable, and it may also affect the vehicle's handling and stability.
Uneven Tire Wear
Worn-out struts can also lead to uneven tire wear, as the suspension system is no longer able to distribute the weight of the vehicle evenly. This can cause the tires to wear down more quickly on one side, leading to a noticeable difference in tread depth.
Nose Diving or Squatting
When you apply the brakes, a vehicle with bad struts may experience "nose diving" or "squatting," where the front or rear of the vehicle dips significantly. This is because the struts are unable to effectively control the vehicle's weight transfer during braking, leading to an unstable and potentially dangerous driving experience.
Leaking Fluid
Another sign of bad struts is the presence of leaking fluid. Struts contain a shock absorber fluid that helps them function properly. If this fluid is leaking, it's a clear indication that the struts are worn out and need to be replaced.
Steering Wheel Vibration
Worn-out struts can also cause the steering wheel to vibrate, especially at higher speeds. This is because the suspension system is no longer able to effectively dampen the forces acting on the vehicle, leading to a noticeable shaking in the steering wheel.
If you notice any of these symptoms in your vehicle, it's important to have the struts inspected and replaced as soon as possible. Ignoring the problem can lead to further damage to the suspension system and potentially compromise the vehicle's handling and safety. Regular maintenance and prompt attention to any issues with the struts can help ensure a smooth, comfortable, and safe driving experience.
What sound does a bad strut make?
A bad strut mount can produce popping or clicking noises during vehicle movement. This often occurs in sudden stops or when accelerating. It's not just an annoyance; it reflects deeper issues within the strut assembly that require immediate attention.
How do bad struts affect a car?
Increased wear on other suspension parts – Worn shocks and struts can have a negative effect on related steering, braking, and suspension components. As the shocks or struts wear, they allow more suspension movement, meaning that other steering, braking and suspension components can suffer the same effects.
How to test struts without removing them?
With the wheels off the ground, grip the coil spring as close to the upper strut mount as possible. Push in and out on the strut and spring while watching for movement of the upper end of the strut piston rod. There should be no free movement. If there is excessive movement, the upper strut mount should be replaced.
How can I tell if my struts are bad?
Symptoms of a bad strut include a bouncy or uncontrolled ride, excessive vehicle nose-dive when braking or rear-end squat during acceleration, leaning or swaying in turns, and unusual noises like clunking, knocking, or squeaking from the suspension. You may also notice leaking fluid, uneven tire wear, or a wobbly steering wheel.
Performance and handling issues
- Bouncy or harsh ride: The vehicle bounces excessively after going over bumps or uneven surfaces.
- Poor stability: The vehicle may feel unstable at higher speeds or have a wobbly sensation.
- Leaning in turns: The car body leans or sways more than usual when taking corners.
- Nose-dive and rear-end squat: The front of the vehicle dips sharply when braking, and the rear may sag during hard acceleration.
Visual and auditory signs
- Leaking fluid: Oil or fluid leaking from the exterior of the shock or strut is a clear sign of a seal failure.
- Uneven tire wear: Tires may show signs of "cupping" or "scalloping" due to uneven contact with the road.
- Unusual noises: Listen for clunking, knocking, squeaking, or grinding sounds, especially when going over bumps or turning.
Steering and vibration issues
- Steering wheel vibration: A vibration or shaking in the steering wheel can be a symptom of worn struts.
- Loose steering feel: The steering might feel less responsive or "sloppy" than usual.
Simple diagnostic test
- The bounce test: Push down firmly on each corner of your car and release. If the vehicle bounces more than once or twice, it's a good indication that the struts are worn and need replacement.
