A smooth ride is something every driver expects from their vehicle. However, when you start hearing clunking noises over bumps or feeling excessive vibration through the steering wheel, it might be time to inspect your suspension. While many people are familiar with struts, a smaller but equally vital component often gets overlooked: the strut mount. This crucial piece of hardware is essential for your car's handling, comfort, and safety.
This guide will dive deep into the world of this essential car part. We'll explain what a strut mount is, why it's so important, and the common signs of failure. We will also provide a detailed overview of the struts and mounts replacement process. Understanding these components can help you make informed decisions about your vehicle's maintenance, ensuring it remains safe and reliable for years to come.
A strut mount is a component that attaches the top of your vehicle's strut assembly to the chassis. It acts as a bridge between your suspension and the car's body, playing a dual role in performance and comfort. Unlike many other car parts that are purely mechanical, the strut mount often contains a rubber or elastomeric insulator. This material is specifically designed to absorb vibrations and impacts from the road, preventing them from transferring into the cabin.
Think of it as a heavy-duty cushion. As the strut moves up and down with the suspension, the strut mount dampens the noise and harshness, contributing to a quieter and smoother driving experience. In many front-wheel-drive vehicles, the strut mount also includes a bearing or bearing plate. This allows the entire strut assembly to pivot as you turn the steering wheel, making it a critical element of your car's steering system. Without a functioning strut mount, your steering would feel stiff and unresponsive.
Because it is constantly under stress from the vehicle's weight and road imperfections, this car part is subject to wear and tear. Over time, the rubber can degrade, crack, or compress, and the internal bearing can fail. Recognizing the signs of a failing strut mount is key to preventing further damage to your suspension system.
Connects the strut to the vehicle body. Absorbs road noise and vibrations. Allows the strut assembly to pivot for steering. Maintains proper wheel alignment.
Diagnosing a bad strut mount can sometimes be tricky, as its symptoms can overlap with other suspension issues. However, there are several telltale signs that point specifically to a problem with this component. Paying attention to these warnings can help you address the issue before it leads to a more costly struts and mounts replacement.
Unusual Noises: This is the most common symptom. You might hear a clunking or knocking sound when driving over bumps, potholes, or uneven surfaces. A popping or creaking noise when turning the steering wheel at low speeds can also indicate that the bearing within the strut mount has failed.
Excessive Vibration: A worn-out strut mount can no longer effectively dampen vibrations. You may feel vibrations through the steering wheel or the floor of the car, especially on rough roads. This can make for an uncomfortable and unsettling driving experience.
Poor Steering and Handling: Since the front strut mount is integral to the steering system, its failure can directly impact handling. You might notice the steering feels loose, stiff, or less responsive. The vehicle may also pull to one side, a sign that the worn mount is affecting your wheel alignment. A complete struts and mounts replacement is often the best solution to restore proper handling.
Uneven Tire Wear: A compromised strut mount can alter the camber and caster angles of your wheel alignment. This misalignment causes tires to wear unevenly, typically on the inner or outer edges. If you notice strange wear patterns during a routine tire check, a faulty strut mount could be the culprit.
Visible Damage: A visual inspection can often confirm your suspicions. Look for cracks, splits, or bulging in the rubber part of the mount. You may also see excessive movement at the top of the strut when you push down on the fender. Corrosion and rust around the mount are also red flags.
A struts and mounts replacement is a job that can be done by a skilled DIY mechanic, but it requires the right tools and a strong emphasis on safety. The process involves compressing the coil spring, which is under extreme tension and can be very dangerous if handled improperly. If you are not confident in your abilities, it is always best to leave this job to a professional.
Here is a general overview of the steps involved in a strut mount replacement. Note that procedures may vary slightly depending on your vehicle's make and model.
Step Number | Action | Description |
|---|---|---|
1 | Prepare the Vehicle | Park on a level surface, engage the parking brake, and chock the rear wheels. Loosen the lug nuts on the wheel you'll be working on, but do not remove them yet. |
2 | Lift and Secure | Use a hydraulic jack to lift the front of the vehicle and support it firmly with jack stands. Never work under a car supported only by a jack. Remove the wheel. |
3 | Disconnect Components | Disconnect the sway bar link, brake line bracket, and any ABS sensor wires from the strut assembly. This will give you the necessary clearance to remove the strut. |
4 | Unbolt the Strut | Loosen and remove the bolts that connect the bottom of the strut to the steering knuckle. Then, access the top of the strut tower under the hood and unbolt the nuts holding the strut mount in place. Be prepared to support the strut as you remove the last nut. |
5 | Compress the Spring | This is the most critical step. Securely attach a high-quality spring compressor to the coil spring. Slowly and evenly tighten the compressor to relieve tension from the top strut mount. |
6 | Remove the Old Mount | With the spring compressed, use a wrench to remove the central nut on top of the strut shaft. You can now take off the old strut mount and any associated hardware. |
7 | Install the New Mount | Place the new strut mount on top of the compressed spring and strut assembly. Ensure it is oriented correctly. Install the new central nut and tighten it to the manufacturer's specified torque. |
8 | Reinstall the Strut | Carefully guide the strut assembly back into the wheel well. Align the studs of the new strut mount with the holes in the strut tower and hand-tighten the top nuts. Reattach the bottom of the strut to the steering knuckle and torque the bolts to spec. |
9 | Final Reassembly | Reconnect the sway bar link, brake line bracket, and ABS sensor. Put the wheel back on and tighten the lug nuts. Lower the vehicle and torque the lug nuts to the correct specification. A struts and mounts replacement for one side is now complete. |
10 | Wheel Alignment | After performing a struts and mounts replacement, it is crucial to get a professional wheel alignment. This will ensure proper handling and prevent premature tire wear. |
It is highly recommended to replace these car parts in pairs (both front or both rear) to maintain balanced handling and suspension performance.

While you can technically drive with a failing strut mount, it is not recommended. Doing so can lead to poor handling, unpredictable steering, accelerated tire wear, and further damage to other suspension components like the struts themselves. For safety, it's best to address the issue promptly.
The lifespan of a strut mount can vary based on driving conditions, climate, and the quality of the part. Generally, they can last between 50,000 to 100,000 miles. If you frequently drive on rough or poorly maintained roads, you may need to replace them sooner.
Yes, it is highly recommended. Since the process for a struts and mounts replacement requires disassembling the entire strut assembly, it is cost-effective and practical to replace both components simultaneously. A new strut paired with an old mount can lead to premature failure and compromise performance.
