A smooth, quiet ride is a sign of a healthy vehicle suspension system. However, when you start hearing clunking noises over bumps or feeling excessive vibration through the steering wheel, it might be time to inspect your car’s suspension. One small but vital component that often gets overlooked is the strut mount. Understanding what it does and how to handle a strut mount replacement can save you from more costly repairs down the road.
This guide will walk you through everything you need to know about the strut mount. We will explain its function, detail the signs of failure, and provide a step-by-step process for replacement. Whether you're a DIY enthusiast or just want to be more informed when talking to your mechanic, this article will equip you with essential knowledge about your vehicle's strut and strut mount assembly.
So, what exactly is a strut mount? In simple terms, it's the component that connects your vehicle's strut assembly to its chassis or body. It acts as a bridge, isolating the tire and suspension noise and vibrations from the rest of the vehicle, ensuring a comfortable and quiet ride.
Most strut mounts consist of a rubber-like insulating material sandwiched between two metal plates. This rubber element is crucial for damping vibrations. The mount also includes a bearing that allows the strut to pivot with the steering wheel as you turn. Without a functional strut mount, your car’s handling would be unpredictable, and the ride would be harsh and noisy.
The relationship between the strut and strut mount is critical. The strut itself is a shock absorber that supports the vehicle's weight and dampens impacts from the road. The strut mount secures this entire assembly in place while allowing for the necessary rotational movement for steering. Think of it as the unsung hero that keeps everything aligned and quiet.
Like any other part of your car, a strut mount can wear out over time. The rubber can crack, the bearing can fail, and the metal components can corrode. Spotting the signs of a bad strut mount early can prevent damage to other suspension parts.
Clunking or Popping Noises: This is often the first sign. You might hear a loud clunk when you turn the steering wheel or drive over bumps and potholes.
Excessive Vibration: A worn-out strut mount can no longer absorb road vibrations effectively, which you'll feel through the steering wheel or the car's body.
Steering Issues: You may notice that your steering feels loose, stiff, or "notchy." This often points to a worn bearing within the mount.
Uneven Tire Wear: Misalignment caused by a failing strut mount can lead to your tires wearing out unevenly and prematurely.
Poor Handling and Alignment: If the vehicle pulls to one side or feels unstable during turns, a faulty strut mount replacement might be needed.
Ignoring these symptoms can lead to bigger problems, including accelerated wear on your struts, tires, and other steering components. A prompt strut mount replacement is the best course of action.
A strut mount replacement is a job that can be done by a confident DIYer with the right tools. However, it involves disassembling a key part of your vehicle's suspension, which is under high tension. Safety should always be your top priority. If you are not comfortable with this process, it is best to consult a professional mechanic.
Before you begin, you will need several tools, including a floor jack, jack stands, a lug wrench, a socket and ratchet set, and most importantly, a spring compressor. Using a spring compressor is non-negotiable, as the coil spring is under extreme pressure and can cause serious injury if not handled correctly.
Here is a general step-by-step guide. Note that specific steps can vary depending on your vehicle's make and model, so always consult your service manual first.
Park your car on a flat, level surface and engage the parking brake. Loosen the lug nuts on the wheel where you will be performing the strut mount replacement, but don't remove them yet.
Use a floor jack to lift the front of the vehicle. Place jack stands securely under the vehicle's frame at the designated lift points. Once the car is stable on the stands, you can remove the lug nuts and take off the wheel.
You will now need to disconnect the components attached to the strut assembly. This typically includes the sway bar link, the brake line bracket, and the ABS sensor wire. Then, remove the bolts that connect the bottom of the strut to the steering knuckle.
Open the hood and locate the top of the strut tower. You will see three or four nuts holding the strut mount in place. While supporting the strut assembly from below, remove these nuts. The entire strut and strut mount assembly can now be carefully lowered and removed from the vehicle.
This is the most critical step. Securely attach the spring compressor to the coil spring according to the tool’s instructions. Slowly and evenly tighten the compressor until the tension is relieved from the upper spring seat.
Once the spring is compressed, use a wrench to remove the large central nut on top of the strut shaft. This nut holds the strut mount onto the strut. With the nut removed, you can take off the old strut mount.
Place the new strut mount on top of the strut assembly, making sure it is oriented correctly. Reinstall the central nut and tighten it to the manufacturer's specified torque.
Now, you can slowly and carefully decompress the spring, ensuring it seats properly against the new strut mount and the lower spring seat. Remove the spring compressor.
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 nuts. Reconnect the bottom of the strut to the steering knuckle and tighten the bolts. Reattach the sway bar link, brake line bracket, and any other components you disconnected.
Tighten the upper strut mount nuts to the correct torque specification. Reinstall the wheel and hand-tighten the lug nuts. Lower the vehicle off the jack stands and use a torque wrench to tighten the lug nuts to the manufacturer's specifications.
After completing a strut mount replacement, it is highly recommended to get a professional wheel alignment. The disassembly and reassembly process can easily affect your car's alignment, and proper alignment is crucial for safety and tire longevity.
The cost can vary significantly based on your vehicle and whether you do the work yourself or hire a professional.
Cost Breakdown for Strut Mount Replacement | DIY Cost | Professional Cost |
|---|---|---|
Parts | A new strut mount can cost anywhere from $30 to $100 per side. | Parts costs are similar, though shops may have a markup. |
Labor | Your time and the cost of any tools you need to buy or rent (like a spring compressor). | Labor can range from $150 to $400 per side, depending on local rates and the complexity of the job. |
Wheel Alignment | An alignment will typically cost between $80 and $150. | This is usually an additional charge on top of the labor for the replacement itself. |
Doing the job yourself can save a significant amount on labor, but it requires the right tools, knowledge, and a strong emphasis on safety. For many, the peace of mind that comes with professional installation is worth the extra cost.
When performing a strut mount replacement, the quality of the new part matters immensely. Using a high-quality strut mount ensures a durable repair, restoring your vehicle's ride comfort and handling for years to come. Low-quality parts can fail prematurely, forcing you to repeat the repair and potentially causing damage to the rest of your suspension.

Yes, you can replace just the strut mount without replacing the entire strut assembly, especially if the strut itself is still in good condition. However, many mechanics recommend replacing the strut and strut mount at the same time, particularly on high-mileage vehicles, to save on future labor costs.
The lifespan of a strut mount can vary but they typically last between 50,000 and 100,000 miles. Factors like driving habits, road conditions, and climate can affect their longevity.
It is highly recommended to replace them in pairs (both front mounts or both rear mounts at the same time). Suspension components wear at a similar rate, so if one side has failed, the other is likely not far behind. Replacing them in pairs ensures balanced handling and stability.
