Is your vehicle making unusual clunking noises when you turn or drive over bumps? Do you feel excessive vibration through the steering wheel? These could be signs that you have a failing strut mount. A worn-out strut mount can compromise your vehicle's handling, comfort, and overall safety. While it may sound like a complex job, performing a struts and mounts replacement can be a manageable task for a confident DIY mechanic. This comprehensive guide will walk you through the process, helping you understand how to replace a strut mount safely and effectively. Understanding the role of the strut mount is crucial before beginning the replacement. The strut mount is a key component of your vehicle's suspension system. It serves as the mounting point that connects the top of the strut assembly to the vehicle's chassis. More than just a simple connector, the strut mount also contains a bearing that allows the strut to pivot with the steering system. A healthy strut mount is essential for smooth steering, proper wheel alignment, and absorbing road imperfections. Over time, the rubber and bearing components of the strut mount can wear out, leading to the need for a struts and mounts replacement.
This article will provide a detailed, step-by-step guide to changing a strut mount. We will cover the necessary tools, safety precautions, and the entire replacement procedure from start to finish. We will also explore the common symptoms of a bad strut mount and answer frequently asked questions to ensure you have all the information you need for a successful struts and mounts replacement.
Before you begin the replacement process, it is important to correctly diagnose the problem. A failing strut mount will present several noticeable symptoms. Recognizing these signs early can prevent further damage to your suspension system.
Unusual Noises: One of the most common indicators of a bad strut mount is noise. You might hear clunking, popping, or creaking sounds, especially when turning the steering wheel at low speeds or driving over bumps and uneven road surfaces. This noise is often caused by the worn-out bearing or deteriorated rubber in the strut mount.
Excessive Vibrations: A healthy strut mount helps to dampen vibrations from the road. When a strut mount fails, you may feel increased vibrations through the steering wheel and the vehicle's floor. This makes for an uncomfortable ride and indicates that the strut mounts are no longer isolating the suspension from the chassis effectively.
Steering Issues: A worn strut mount can affect your vehicle's steering. You might experience a stiff or "memory steer" sensation, where the steering wheel is slow to return to its center position after a turn. This is a significant safety concern and a clear sign that the strut mount bearing is binding.
Uneven Tire Wear: Misalignment is a common consequence of a failed strut mount. When the strut mount is worn, it can alter the camber and caster angles of your wheels. This improper alignment can lead to accelerated and uneven tire wear, costing you money in the long run.
Visible Wear and Tear: A physical inspection can often confirm a bad strut mount. Look for cracks, splits, or separation in the rubber part of the strut mount. You might also see that the center portion of the strut mount has sagged or dropped, creating a visible gap.
Having the right tools is essential for a smooth and safe struts and mounts replacement. Attempting this job without the proper equipment can be dangerous and may lead to damaging your vehicle. Please gather the following tools before you start.
Tool Category | Specific Tools Needed |
|---|---|
Safety Equipment | Safety glasses, gloves, jack stands, wheel chocks |
Lifting & Support | Floor jack, jack stands |
Wrenches & Sockets | Socket set (metric and/or standard), wrench set, torque wrench |
Specialty Tools | Spring compressor, strut socket or pass-through socket set |
General Hand Tools | Breaker bar, hammer or mallet, pry bar, wire brush |
The most critical specialty tool for this job is the spring compressor. The coil spring is under extreme tension, and attempting to disassemble the strut assembly without properly compressing the spring can result in serious injury or death. Always use a high-quality spring compressor and follow its instructions carefully. A successful struts and mounts replacement relies on having these tools ready.
With your tools gathered and your new strut mount ready, you can begin the replacement process. Please follow these steps carefully for a successful installation. Remember, safety is your top priority throughout this procedure.
First, park your vehicle on a flat, level surface and engage the parking brake. Place wheel chocks behind the rear wheels to prevent any movement. Next, use a breaker bar or lug wrench to loosen the lug nuts on the wheel where you will be replacing the strut mount. Do not remove them completely yet.
Using a floor jack, lift the front of the vehicle at the manufacturer's recommended lift point. Once it is raised high enough to remove the wheel, place a jack stand securely under the frame or a designated support point. Gently lower the vehicle onto the jack stand, ensuring it is stable. Never work under a vehicle supported only by a jack. Now, you can finish removing the lug nuts and take off the wheel.
The strut assembly is connected to the steering knuckle at the bottom and the strut tower in the engine bay at the top. You will need to disconnect it at both ends. Start by detaching any brake lines, ABS sensor wires, or sway bar end links that are clipped to the strut. Take photos if you need help remembering how they go back.
Next, remove the large bolts that connect the bottom of the strut to the steering knuckle. These bolts are often very tight, so you may need a breaker bar. Once those are removed, move to the engine bay. Locate the top of the strut tower and remove the nuts that secure the top of the strut mount to the chassis. Usually, there are three or four of them. Leave one nut loosely threaded to hold the strut assembly in place while you work. Now, support the bottom of the strut assembly and remove the final nut. Carefully maneuver the entire strut assembly out from the wheel well.
This is the most critical and potentially dangerous part of the job. Place the strut assembly in a secure position. Carefully attach the spring compressor to the coil spring according to the tool's instructions. Slowly and evenly tighten the compressor, alternating between sides, to relieve the tension from the spring.
Once the spring is compressed and you can see it is loose from its seats, you can safely remove the top nut of the strut. This nut holds the old strut mount in place. You may need a special strut socket or pass-through wrench to hold the strut shaft while you turn the nut. With the nut removed, you can take off the old strut mount, the upper spring seat, and any associated hardware.
Inspect the other components of the strut assembly, like the dust boot and bump stop, and replace them if they are worn. Place the new strut mount onto the top of the strut assembly, ensuring it is oriented correctly. Reinstall any washers or hardware and tighten the new top strut nut to the manufacturer's specified torque.
With the new strut mount secured, you can now slowly and carefully decompress the spring. Again, alternate between sides to release the tension evenly. Make sure the spring seats correctly in the upper and lower perches as the tension is released. A poorly seated spring can cause noise and handling problems.
Carefully guide the newly assembled strut back into the wheel well. Start by aligning the studs on the new strut mount with the holes in the strut tower and loosely install the top nuts. Next, align the bottom of the strut with the steering knuckle and reinstall the lower bolts.
Torque all fasteners to the manufacturer's specifications. This is crucial for safety. Reattach the brake lines, sensor wires, and sway bar end link that you previously disconnected. Reinstall the wheel and hand-tighten the lug nuts.
Raise the vehicle off the jack stand, remove the stand, and lower the vehicle to the ground. Now, use a torque wrench to tighten the lug nuts to the specified torque in a star pattern.
Finally, it is highly recommended to get a professional wheel alignment after performing a struts and mounts replacement. Replacing these components will almost certainly alter your vehicle's alignment angles.
While you can technically drive with a bad strut mount for a short time, it is not recommended. It compromises safety, affects steering control, and can lead to further damage to your tires and other suspension components. Addressing a faulty strut mount promptly is always the best course of action.
Yes, it is highly advisable to replace strut mounts in pairs (both front or both rear). If one strut mount has failed due to age and wear, the other on the same axle is likely not far behind. Replacing both ensures balanced handling and performance.
A strut is the main shock-absorbing component that also serves as a structural part of the suspension. The strut mount is the part that connects the top of the strut to the vehicle's body. The strut mount allows the strut to pivot for steering and isolates noise and vibration. A complete struts and mounts replacement addresses both key areas.
The cost can vary widely depending on the vehicle and whether you do it yourself or hire a professional. DIY replacement saves on labor costs, but you must invest in tools. The new strut mounts themselves are generally affordable parts.
