Your vehicle suspension system plays a crucial role in providing a smooth, comfortable ride. A major component of this system is the strut mount. When this part begins to wear out, you might experience unusual noises, poor handling, or a bumpy ride. Learning how to change a strut mount can save you time, improve your driving experience, and restore the performance of your vehicle.
This comprehensive guide will explain the entire strut mount replacement process in detail. We will walk you through the necessary tools, the safety precautions to take, and the exact steps required to complete a successful strut mount replacement. By the end of this guide, you will have a thorough understanding of your vehicle suspension components, particularly the strut and strut mount.
To fully appreciate the strut mount replacement process, it helps to know what this component actually does. A strut mount is essentially a sandwich-like component made of rubber or polyurethane, often containing a bearing in the center. It connects the suspension strut to the vehicle body.
The rubber portion acts as an insulator. It absorbs tire vibrations, road noise, shocks from potholes, minimizing the impact felt inside the cabin. The bearing part allows the strut to pivot smoothly when you turn the steering wheel. Because the strut mount constantly bears the weight of the vehicle while absorbing heavy impacts, it undergoes significant stress. Over time, the material degrades, necessitating a strut mount replacement. Understanding the relationship between the strut and strut mount ensures you maintain the entire suspension system properly.
How do you know it is time to perform a strut mount replacement? Recognizing the early warning signs can prevent further damage to your suspension system. Please be observant of the following symptoms:
Clunking Noises: If you hear a loud clunking or knocking sound from the front or rear wheels when driving over bumps, your strut mount has likely failed.
Stiff Steering: A worn bearing inside the strut mount can cause your steering wheel to feel unusually stiff or difficult to turn.
Uneven Tire Wear: When a strut mount deteriorates, it alters the alignment of the suspension system, leading to premature or uneven tire wear.
Vibration During Operation: Excessive vibration felt through the steering wheel often points to a degraded rubber insulator within the strut mount.
If you experience these issues, investigating how to change a strut mount should become a priority.
Before you begin the strut mount replacement, you must gather the correct tools. Having the right equipment ensures safety and efficiency throughout the procedure. Please review the table below for a complete list of required items.
Tool Name | Purpose During Strut Mount Replacement |
|---|---|
Jack stand | Securely lifting the vehicle off the ground |
Socket wrench set | Removing various bolts from the suspension system |
Strut spring compressor | Safely compressing the coil spring on the strut |
Torque wrench | Tightening fasteners to manufacturer specifications |
Penetrating fluid | Loosening rusted or stubborn bolts safely |
Safety glasses | Protecting your eyes from debris during the process |
New strut mount | The replacement component for your vehicle |
With these tools prepared, you are ready to move forward with the strut mount replacement.
Safety is the most important factor when learning how to change a strut mount. Please park your vehicle on a flat, level surface. Engage the parking brake to prevent any unintended movement.
Loosen the lug nuts on the wheel where you plan to replace the strut mount. Do this before lifting the vehicle. Next, place the jack beneath the designated lifting point of your vehicle and raise it carefully. Slide the jack stands underneath the chassis to secure the vehicle. Never rely solely on a hydraulic jack when working on a strut and strut mount system. Once the vehicle rests securely on the jack stands, remove the lug nuts completely and take off the wheel.
To proceed with the strut mount replacement, you must first extract the entire strut assembly from the vehicle. Begin by locating the brake line bracket and the sway bar link attached to the strut body. Use your socket wrench to carefully remove these bolts.
Next, find the lower mounting bolts connecting the strut to the steering knuckle. These bolts are often tightly secured and may require an application of penetrating fluid. Allow the fluid to sit for a few minutes before attempting to loosen them. Once removed, support the lower control arm so it does not drop abruptly.
Move to the engine bay to access the upper strut mount nuts. These nuts secure the strut mount to the chassis of the vehicle. Carefully remove these nuts while supporting the strut assembly from below. If you do not support the assembly, it may fall and cause injury or damage. Gently maneuver the entire strut and strut mount assembly out of the wheel well.
Now that you have the strut assembly on your workbench, you can begin the core part of the strut mount replacement. You must exercise extreme caution during this step, as the coil spring holds a tremendous amount of stored energy.
Attach your strut spring compressor tool to the coil spring. Tighten the compressor evenly on both sides until the spring pulls slightly away from the upper spring seat. The spring must be fully compressed and secure before you proceed.
Once the spring tension is safely contained, locate the center nut on top of the strut mount. Use a socket wrench to loosen and remove this nut. Carefully lift the old strut mount off the strut shaft. Take a moment to inspect the other components, such as the dust boot and the bump stop. If they appear damaged, consider replacing them alongside the strut mount.
You are now ready to install the new strut mount. Clean the top of the strut shaft and the spring seat to ensure a smooth installation. Place the new strut mount onto the strut shaft, ensuring it aligns perfectly with the coil spring and the upper spring seat.
Thread the center nut back onto the strut shaft. Use your torque wrench to tighten the nut to the specific torque setting recommended by your vehicle manufacturer. Do not overtighten, as this can damage the new strut mount bearing.
With the new strut mount securely fastened, you can begin releasing the tension on the strut spring compressor. Loosen the compressor evenly on both sides, ensuring the coil spring seats correctly into the new strut mount and the lower spring perch. Your new strut and strut mount assembly is now ready to go back into the vehicle.
Guide the newly assembled strut and strut mount back into the wheel well. Align the upper studs of the strut mount with the holes in the vehicle chassis. Have an assistant thread the upper mounting nuts loosely from inside the engine bay to hold the assembly in place.
Next, align the lower portion of the strut with the steering knuckle. Insert the lower mounting bolts and tighten them securely. Reattach the brake line bracket and the sway bar link.
Use your torque wrench to tighten all lower bolts to the manufacturer's specifications. Finally, return to the engine bay and fully torque the upper strut mount nuts.
Reinstall the wheel, hand-tighten the lug nuts, and carefully lower the vehicle off the jack stands. Once the vehicle sits firmly on the ground, use the torque wrench to secure the lug nuts completely. You have now successfully completed a strut mount replacement. We highly recommend taking your vehicle for a professional wheel alignment, as altering the strut and strut mount can shift the suspension geometry.
For an individual with moderate mechanical experience, a strut mount replacement generally takes between two to four hours per side. The time required depends heavily on the condition of your suspension system. Rusted bolts can extend the duration of the strut mount replacement.
While it is technically possible to replace a single strut mount, automotive professionals strongly advise replacing suspension components in pairs. If the left strut mount has failed, the right strut mount has likely experienced the same amount of wear. Replacing them together ensures balanced handling and even tire wear.
You do not strictly have to replace the strut when performing a strut mount replacement. However, because you must completely disassemble the strut and strut mount to change the mount, it is often more cost-effective to replace both parts simultaneously if the strut is nearing the end of its lifespan. This saves you from performing the exact same labor twice.
Yes, a spring compressor is absolutely mandatory. The coil spring is under immense pressure. Attempting a strut mount replacement without properly compressing the spring can result in the assembly flying apart with lethal force. Always prioritize safety when dealing with a strut and strut mount.
