Strut Mounts: The Unsung Heroes of Your Car's Suspension System

When it comes to vehicle maintenance, strut mounts are often overlooked, yet they play a critical role in your car's suspension system. This article delves into the importance of strut mounts, the interplay between struts and strut mounts, and the key indicators that it's time for a strut mount replacement.

Understanding Strut and Strut Mount
A car's suspension system is a complex assembly designed to ensure a smooth ride, maintain tire contact with the road, and provide vehicle control and handling. At the heart of this system are struts and strut mounts.

What is a Strut?

A strut is a crucial component of a vehicle's suspension system that combines the functions of a shock absorber and a spring. Its primary roles include:

Absorbing Shock: It dampens the impact of bumps and potholes, providing a smoother ride.

Supporting the Vehicle's Weight: The spring within the strut bears the vehicle's weight, maintaining proper ride height.

Enhancing Stability and Control: It helps keep the tires in contact with the road, which is essential for steering and braking.

Struts are typically found in the front suspension systems of most vehicles, though some cars also have rear struts.

What is a Strut Mount?
The strut mount is a vital component that attaches the strut to the vehicle's chassis. It serves several important functions:

Absorbing Vibrations: The strut mount helps to isolate vibrations and road noise from the cabin, contributing to a quieter and more comfortable ride.

Bearing Load: It supports the strut and the weight of the vehicle, aiding in maintaining proper alignment.

Facilitating Steering: In front-wheel-drive vehicles, the strut mount allows the strut to pivot as the wheels turn, playing a crucial role in steering.

The Interplay Between Struts and Strut Mounts

The relationship between struts and strut mounts is symbiotic. While the strut absorbs road impacts and provides structural support, the strut mount ensures that these forces are effectively transferred to the chassis without compromising ride quality. A well-functioning strut mount can extend the life of your struts by minimizing wear and tear. Conversely, a damaged strut mount can lead to premature strut failure and adversely affect vehicle handling and safety.

Signs You Need a Strut Mount Replacement
Recognizing when it's time for a strut mount replacement is crucial for maintaining your vehicle's performance and safety. Here are some key indicators:

Unusual Noises: If you hear clunking, knocking, or creaking sounds, especially when driving over bumps or making turns, it could indicate that the strut mounts are worn out or damaged.

Poor Handling: A noticeable decline in vehicle handling, such as increased body roll, excessive bouncing, or difficulty steering, can be a sign of strut mount issues.

Uneven Tire Wear: Strut mounts that are not functioning properly can lead to misalignment, resulting in strut mounts uneven tire wear.

Visible Damage: Upon inspection, visible cracks or other damage to the strut mounts necessitate immediate replacement.

Vibrations and Noise in the Cabin: Increased vibrations and noise inside the vehicle, particularly from the front end, can be symptomatic of worn strut mounts.

The Process of Strut Mount Replacement

Strut mount replacement is a task that requires mechanical knowledge and the right tools. While it can be performed by skilled DIY enthusiasts, it's often recommended to have a professional mechanic handle the replacement to ensure safety and proper installation.

Steps Involved in Strut Mount Replacement:

Safety First: Ensure the vehicle is on a flat surface, engage the parking brake, and use jack stands for support.

Remove the Wheel: Loosen the lug nuts, lift the vehicle, and remove the wheel to access the strut assembly.

Detach the Strut Assembly: Remove the bolts securing the strut to the steering knuckle and the top bolts connecting it to the chassis.

Compress the Spring: Use a spring compressor to safely compress the coil spring, allowing the strut mount to be removed without releasing the spring force.

Replace the Strut Mount: Remove the old strut mount, inspect the strut and spring for any strut mount replacement additional wear, and then install the new mount.

Reassemble: Reinstall the strut assembly in reverse order, ensuring all bolts are securely tightened and torqued to the manufacturer's specifications.

Wheel Alignment: After replacing the strut mounts, it's crucial to have the vehicle's alignment checked and adjusted if necessary to ensure optimal handling and tire wear.
The Importance of Regular Maintenance

Regular inspection and maintenance of struts and strut mounts are essential for vehicle safety and performance. Here are some tips to keep in mind:

Routine Checks: During regular vehicle maintenance, have the struts and strut mounts inspected for any signs of wear or damage.

Listen to Your Vehicle: Pay attention to any unusual noises or changes in handling, as these can be early warning signs of suspension issues.

Timely Replacement: Don't delay replacing worn or damaged strut mounts. Prompt replacement can prevent further damage to the suspension system and ensure a safe and comfortable ride.


Strut mounts may not receive as much attention as other car components, but their role in the suspension system is indispensable. By understanding the function of struts and strut mounts, recognizing the signs of wear, and knowing when to replace them, you can maintain your vehicle's performance and safety. Regular maintenance and timely strut mount replacement will ensure that your car continues to provide a smooth, comfortable, and safe driving experience.

Investing in the health of your suspension strut mounts system is an investment in your vehicle's longevity and your peace of mind on the road. Don't wait until a small problem becomes a major repair-- keep an eye on your strut mounts and keep your ride running smoothly.
