The suspension system of a car, truck, or SUV is crucial for its optimal operation. Struts, which function as dampers, provide a comfortable ride under various driving conditions. However, their performance depends on the mount to which they are attached. Strut mounts degrade over time, causing symptoms such as shock and noise transmission issues. Understanding the signs and handling the need for strut mount replacement is essential.
Signs of a Bad Strut Mount
The most typical symptoms of a bad strut mount include some of the following.
“Clunking” In Front End
A worn strut mount can cause a noticeable “clunking” in the front end of a vehicle, causing excessive strut play. This can be heard by occupants and requires replacement after examination for further damage.
Excessive noise or vibration
Excessive noise or vibration while driving is another sign of a bad strut mount, as it compromises its ability to function as a reliable buffer.
Rapid Tire Wear
Front end geometry can deviate from specification due to wear on upper strut mounts, affecting tee settings and potentially accelerating tire wear, especially in recently replaced tires.
Poor Handling
Strut mount failure can affect a vehicle’s caster setting, similar to toe setting. Upper shock mount wear or failure can cause front end geometry changes, necessitating replacement before front end alignment.
Wear of Other Suspension Components
Strut mounts age, causing wear and tear on suspension parts like front end bushings and shock absorbers, leading to secondary issues affecting vehicle handling.
What Causes Strut Mount Failure?
Strut mount failure is primarily due to regular wear and tear, as they are subjected to constant movement and weight transfer. These components start to wear as soon as installed and continue to wear relentlessly. Environmental stressors like rainwater, ice, and road salt worsen this wear, leading to eventual failure.
Strut Mount Replacement Cost
Strut mount replacement costs vary depending on the vehicle’s make and model, typically ranging from $150 to $300. Budget mounts are used on sedans, while high-end performance or sports cars require higher costs and dealer labor rates.
