8. Signs Your Car Needs New Struts

Knowing when to replace your car’s struts is essential for maintaining a safe and comfortable ride. Struts play a crucial role in your vehicle’s suspension system, and worn struts can negatively impact handling, braking, and overall stability. Here are some key signs that indicate your car needs new struts.

8.1. Excessive Bouncing

The Symptom: One of the most noticeable signs of worn struts is excessive bouncing after hitting a bump. If your car continues to bounce several times after going over a bump, it’s likely that the struts are no longer effectively damping the suspension.
The Test: Perform the bounce test by pushing down firmly on each corner of the vehicle. If the car bounces more than two or three times, the struts may need to be replaced.

8.2. Nose Diving During Braking

The Symptom: Worn struts can cause the front of the car to dip excessively during braking, a phenomenon known as “nose diving.” This can increase braking distance and reduce control.
The Cause: When struts are worn, they don’t provide enough resistance to counteract the weight transfer during braking, leading to the front end dipping.

8.3. Uneven Tire Wear

The Symptom: Struts that aren’t functioning properly can cause uneven tire wear. You may notice that the tires are wearing more on one side than the other, or that there are bald spots on the tires.
The Reason: Worn struts can cause the wheels to lose contact with the road intermittently, leading to irregular wear patterns.

8.4. Poor Handling

The Symptom: If your car feels unstable or difficult to control, especially during turns or at higher speeds, it could be a sign of worn struts.
The Explanation: Struts help maintain stability and control by keeping the tires in contact with the road. When they are worn, they can’t effectively dampen the suspension, leading to poor handling.

8.5. Leaking Fluid

The Symptom: Visible fluid leaking from the struts is a clear indication that they are failing. The fluid is hydraulic oil that is essential for the strut’s damping action.
The Consequence: Once the fluid leaks out, the strut’s ability to control the suspension is significantly reduced.

8.6. Clunking Noises

The Symptom: A clunking or knocking noise coming from the suspension area, especially when driving over bumps, can indicate worn struts or strut mounts.
The Source: The noise can be caused by the strut bottoming out or by worn bushings and mounts.

8.7. Vehicle Instability at Highway Speeds

The Symptom: If your car feels shaky or unstable at highway speeds, it could be due to worn struts.
The Effect: Worn struts can cause the car to wander or feel floaty, making it difficult to maintain a straight line.

8.8. Increased Braking Distance

The Symptom: Worn struts can increase braking distance, making it take longer to stop the car.
The Impact: This is because worn struts can reduce the tires’ contact with the road, decreasing braking efficiency.
