A smooth, quiet ride is something every driver wants. When you hear clunking noises, feel excessive vibrations, or notice uneven tire wear, it's easy to suspect major issues. Often, the culprit is a small but vital component of your vehicle's suspension system: the strut mount. Understanding what this part does, how to spot a failing one, and the process of a strut mount replacement can save you time, money, and stress.
This guide will walk you through everything related to the strut mount. We will cover its function, common signs of failure, and a detailed look at how to replace it. By the end, you'll have a clear understanding of why maintaining this part is crucial for your vehicle's safety and performance.
A strut mount is the component that attaches your vehicle's strut assembly to its chassis. It acts as a bridge between the suspension and the body of the car. While it may seem simple, it performs several critical functions that directly impact your driving experience.
First, it serves as an insulator, absorbing vibrations and noise from the road. This prevents the harshness of bumps and uneven surfaces from transferring into the vehicle's cabin, ensuring a more comfortable ride. Second, in most front-wheel-drive vehicles, the upper strut mount includes a strut mount bearing. This bearing is a pivot point for the steering system, allowing the front wheels to turn smoothly left and right.
Without a functioning strut mount, your car's handling, stability, and alignment would be severely compromised. It's a key element that works with the rest of your suspension to keep your tires firmly on the ground and your steering precise.
Identifying a bad strut mount early can prevent more significant damage to your suspension system and tires. Here are the most common symptoms to watch for:
Symptom | Description |
|---|---|
Unusual Noises | A clunking or popping sound when driving over bumps, potholes, or making sharp turns is a classic sign. This is often caused by the loosening of internal components. |
Excessive Vibrations | If you feel more road vibrations through the steering wheel or the car's body, the mount's dampening capabilities may have worn out. |
Steering Issues | Difficulty turning the steering wheel, a feeling of stiffness, or a "memory steer" (where the wheel doesn't return to center easily) can point to a seized strut mount bearing. |
Uneven Tire Wear | A bad strut mount can throw off your vehicle's wheel alignment, leading to premature and uneven wear on your tires, particularly "cupping." |
Poor Handling | The vehicle may feel less stable, especially when cornering or driving at higher speeds. This indicates a loss of connection between the strut and chassis. |
If you notice any of these signs, it's time to inspect your suspension and consider a strut mount replacement. Ignoring them can lead to further damage to the strut assembly, tires, and other steering components.
Changing a strut mount is a job that requires mechanical knowledge, the right tools, and a strong emphasis on safety. While the terms "change" and "replace" are often used interchangeably, let's break down the step-by-step process. A strut mount replacement involves removing the entire strut assembly from the vehicle, compressing the coil spring, and then replacing the old mount.
Before you begin, gather the necessary tools. This is not a task for a basic toolkit. Jack and jack stands Lug wrench Socket and ratchet set Wrenches (box and open-end) Torque wrench Strut spring compressor (CRITICAL for safety) Pry bar Penetrating oil
Safety is paramount. Never work under a vehicle supported only by a jack. Always use jack stands rated for your vehicle's weight. The coil spring is under extreme tension; mishandling a spring compressor can result in serious injury. If you are not confident, leave this job to a professional.
The process of a strut mount replacement can be broken down into three main stages: removing the strut assembly, replacing the mount itself, and reinstalling the assembly.
Prepare the Vehicle: Park on a level surface, engage the parking brake, and loosen the lug nuts on the wheel you'll be working on. Do not remove them completely yet.
Lift the Vehicle: Use a jack to lift the vehicle until the wheel is off the ground. Place a jack stand securely under the frame rail or a designated lift point.
Remove the Wheel: Finish unscrewing the lug nuts and remove the wheel to expose the strut assembly.
Disconnect Components: Disconnect the sway bar link, ABS sensor wire, and brake line from the strut. Take care not to damage these components. It's often best to unbolt their brackets rather than detaching the lines themselves.
Unbolt the Lower Strut: Remove the two 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 or penetrating oil.
Unbolt the Upper Strut Mount: Access the top of the strut mount from under the hood or in the trunk (for rear struts). Loosen and remove the three or four nuts holding the strut mount to the vehicle's chassis. Have a hand ready to support the strut assembly as you remove the last nut, so it doesn't fall.
Remove the Assembly: Carefully maneuver the strut assembly out of the wheel well.
Compress the Spring: Secure the strut assembly in a vise or on a stable workbench. Attach the strut spring compressor to the coil spring according to the tool's instructions. Slowly and evenly tighten the compressor bolts, alternating between sides, to relieve tension from the strut mount.
Remove the Top Nut: Once the spring is compressed, use a wrench to remove the large central nut on top of the strut rod. This nut holds the strut mount in place.
Disassemble: With the top nut removed, you can now take off the old strut mount, the strut mount bearing (if separate), and any associated washers or insulators. Pay close attention to the order of disassembly.
Install the New Mount: Install the new strut mount bearing and strut mount in the reverse order of removal. Make sure all components are seated correctly.
Tighten the Top Nut: Hand-tighten the new central strut nut. You will torque it to the manufacturer's specification once the assembly is back in the car.
Decompress the Spring: Slowly and carefully loosen the spring compressor, ensuring the spring seats correctly in the upper and lower perches.
Position the Assembly: Guide the strut assembly back into the wheel well, pushing the top strut mount studs through the holes in the chassis.
Secure the Top Mount: Hand-tighten the upper mounting nuts to hold the assembly in place.
Reconnect the Lower Strut: Align the bottom of the strut with the steering knuckle and insert the two large bolts.
Reconnect Other Components: Reattach the sway bar link, ABS sensor bracket, and brake line bracket.
Torque to Spec: Now, use a torque wrench to tighten all bolts and nuts to the vehicle manufacturer's specified values. This includes the upper mount nuts, lower strut bolts, and the central strut rod nut.
Reinstall Wheel and Lower Vehicle: Mount the wheel and hand-tighten the lug nuts. Lower the vehicle off the jack stands, and then use a torque wrench to tighten the lug nuts in a star pattern.
Get an Alignment: After completing a strut mount replacement, a professional wheel alignment is essential. The process of removing and reinstalling suspension components will almost always affect your car's alignment settings.
While you can technically drive with a worn strut mount, it is not recommended. Doing so compromises your steering, braking, and overall stability. It also accelerates wear on your tires and other suspension parts, leading to more expensive repairs down the line.
Yes, it is highly recommended. The labor involved in accessing the strut mount is nearly identical to replacing the entire strut. Since you have to remove the assembly anyway, replacing the strut and mount together ensures the entire system is refreshed and saves you from paying for the same labor twice.
The cost varies greatly depending on the vehicle model and labor rates. The part itself is relatively inexpensive, but the labor can be significant due to the complexity of the job. Expect to pay several hundred dollars per corner.
Yes. Suspension components should always be replaced in pairs (both front or both rear) to ensure even handling and performance. Replacing only one strut mount can create an imbalance, affecting stability and steering.
