Bad Strut Mount Symptoms

Reading Time: 5 minutes

A strut mount is one of the lesser-known parts of a vehicle’s suspension system. Small, flat, and unremarkable, it is easily overshadowed by other components with a more active role in the suspension, like shock absorbers and struts.

Although this component is often overlooked, the suspension system can’t function properly without it. A damaged strut mount can cause strange noises, poor handling, and overall ride discomfort.

Do you think your car may have a bad strut mount? If it exhibits one or more of the symptoms below, you may be right.

Signs of a Bad Strut Mount

A strut mount is a part of the vehicle’s suspension system that connects the strut to the chassis or body of the vehicle. It keeps the strut firmly in place when the car is in motion. The mount also insulates tire noise and vibrations from the vehicle by cushioning road bumps and rough driving conditions.

Watch out for the following symptoms to determine if a bad strut mount is causing issues in your vehicle:

Weird Noises

If you hear clunking or squeaking coming from the suspension system while driving, this could mean the mount has worn out. The noise comes from two or more metal components hitting each other without any insulation.

Front strut mounts may also make a noise when you turn the steering wheel.

Uneven Tire Wear

If your tires are wearing out unevenly, this could be a sign that the strut mount needs to be replaced. A damaged strut mount may wobble and fail to keep the wheels aligned, leading to uneven tire wear as they drag against the pavement.

Excessive Vibration

Aside from connecting the struts to the chassis, strut mounts also provide insulation. If they’re damaged, they won’t be able to cushion noise and vibrations.

A bad strut mount likely won’t have any rubber left for insulation, leading to excessive vibrations while driving.

Steering Issues

In some vehicles, the strut mount also serves as the steering pivot. This means that when it fails, the steering movement’s smoothness and response time may be affected. This could lead to steering issues, as the steering and suspension systems are interlinked.

Corrosion

Because most strut mounts are made of metal, they can easily succumb to corrosion when exposed to moisture.

Worn Rubber

If the rubber inside the mount has cracked or disintegrated in any way, it’s time for a strut mount replacement. Keep an eye out for this symptom when you visually inspect your suspension system.

Excessive Movement

The strut mount is supposed to help cushion the impact of road bumps on the car. If it malfunctions, it could loosen and fail to keep the strut in place.

This could result in abnormal vehicle bounce and excessive movement while driving.

Worn Struts

If you notice your vehicle’s struts are wearing out faster than they should, a failed strut mount may be the culprit. A perfectly working mount should handle the weight of the vehicle and keep everything in place. A failed one can’t, causing the strut to fall out and knock against other components within the suspension. This can lead to premature wear and costly repairs.

What Causes Strut Mounts to Go Bad?

Strut mounts can go bad from natural wear and tear. Because it is a wear item, the strut mount will require replacement after a certain number of miles or years.

Other causes of a faulty strut mount include impact damage and contamination. Minor accidents and bad weather may affect the strut mount and cause it to fail prematurely.

At the first sign of wear, consider replacing your vehicle’s strut mounts immediately. It is strongly recommended that you replace both strut mounts on either side of your car for a seamless, even ride. Often, when one mount fails, the other is not too far behind.

Prevent unexpected car trouble by replacing all your strut mounts at the same time.

What to Look for in a New Strut Mount

When in the market for a new strut mount, the wide variety of options available can get confusing. To help narrow down your options, here are some factors you should keep in mind:

Application

Always guarantee fit before purchasing a strut mount for your vehicle’s suspension. The replacement should be compatible with the year, make, and model of your ride to ensure functionality and easy installation.

Quality

The new strut mount should be sturdy and resistant to premature wear, as it is a fundamental component in your vehicle’s suspension system. You can either pick a replacement made of the same material as your factory-installed strut mount or invest in an upgraded strut mount.

If you opt for the latter, consult your mechanic before deciding on anything to ensure your enhanced replacement is compatible with your ride. 

Be sure to choose a top-grade mount to ensure long-term functionality. Restore your car’s handling performance and ride quality with a durable strut mount replacement.

How Much is a Strut Mount Replacement?

The price of an aftermarket strut mount replacement ranges from $10 to $350. However, this price range is for the part only. You’ll need to spend more to have it installed by a professional.

The cost of a new strut mount also depends on its brand, series, intended location, and quantity. It can be bought individually, in sets, or as part of a kit.
