How to Change Strut Mounts: A Comprehensive Guide
Strut mounts are an essential yet often overlooked component of your vehicle's suspension system. They play a critical role in ensuring a smooth and comfortable ride while maintaining steering precision and stability. This guide takes you through everything you need to know about strut mounts—including how to change them—so you can tackle this task with confidence and keep your car performing at its best.
What Is a Strut Mount and Why Is It Important?
A strut mount is a crucial part of your car's suspension system, acting as the connection point between the strut assembly and the vehicle's chassis. It ensures smooth strut movement while isolating vibrations and road noise from the cabin. Some strut mounts also house a bearing, allowing the strut to rotate for easier steering. There are two main types of strut and strut mount setups:
Standard strut mounts – Typically used in rear suspension systems and serve a simpler purpose. Strut mounts with bearings – Found in front suspension systems, as they also accommodate steering movements. When functioning correctly, strut mounts contribute to a quiet, stable ride with improved handling and reduced wear on other components. Faulty strut mounts, however, can lead to discomfort, reduced control, and potential damage to your suspension system.
A strut mount is a critical component of a vehicle's suspension system, providing the connection between the strut assembly and the chassis. The strut mount not only ensures proper alignment but also helps absorb shocks and vibrations, improving overall driving comfort. Regular inspection of the strut mount is essential to maintain peak performance, as a worn or damaged strut mount can result in increased noise, reduced stability, and compromised handling. Keeping your strut mount in good condition is key to ensuring your vehicle functions smoothly and reliably.
Signs of a Faulty Strut Mount
Over time, wear and tear can cause strut mounts to fail, leading to various warning signs. Here’s a table summarizing the common symptoms of a faulty strut mount and what they signify:
| Symptom | Possible Cause |
|---|---|
| Clunking noises when driving | Damaged or loose strut mount causing the strut assembly to rattle. |
| Vibrations in the steering wheel | Worn bearing in the strut mount affecting steering precision. |
| Uneven tire wear | Misalignment or poor contact between suspension components. |
| Poor handling and stability | Excessive play or wear in the mount, reducing the suspension's effectiveness in absorbing road impact. |
| Increased road noise or harsh ride | Failed isolating material in the mount leading to more vibration and noise entering the cabin. |
Tools and Preparation
Replacing a strut mount requires some preparation. Below is a breakdown of tools you’ll need and steps to prepare safely for the task.
Tools Needed
| Tool | Purpose |
|---|---|
| Socket wrench set | To remove bolts and nuts. |
| Strut spring compressor | To safely compress the strut spring. |
| Torque wrench | For proper tightening to manufacturer specs. |
| Screwdrivers (Flat/Phillips) | For disassembly tasks. |
| Jack and jack stands | To lift and stabilize the vehicle. |
| Penetrating lubricant | To loosen rusty or stuck bolts. |
| Safety gloves and goggles | Protect yourself during the process. |
Safety Precautions
Choose a flat, well-lit work area and ensure the car is on a stable surface. Use quality jack stands to support the vehicle and avoid relying solely on a jack. Wear safety gloves and eye protection, especially when working with compressed springs or old hardware.
Keep a repair manual specific to your vehicle handy for reference. Preparing properly will save time and ensure your safety while working on the strut and strut mount replacement.
Step-by-Step Guide to Changing a Strut Mount
Replacing a strut mount isn’t overly complicated, but it does take time and attention to detail. Below is a comprehensive step-by-step guide.
1. Lift and Secure the Vehicle
Park the car on level ground and engage the parking brake. Use a jack to lift the vehicle and secure it on jack stands. Remove the wheel to access the strut assembly.
2. Detach the Strut Assembly
Locate the strut assembly by identifying the bolts securing it to the steering knuckle and chassis. Spray penetrating lubricant on stubborn bolts to make removal easier. Use a socket wrench to disconnect the strut from the chassis and knuckle.
3. Compress the Strut Spring
Position the spring compressor on the coil spring and tighten it gradually. This step is crucial for safety to release tension from the spring before removing the strut mount.
4. Remove the Old Strut Mount
Once the spring is compressed, remove the nut holding the strut mount in place using a socket or impact wrench. Carefully detach the old strut mount, taking note of its orientation.
5. Inspect Components
Inspect the strut, spring, and other suspension components for wear or damage. Replacing the entire strut assembly may be more cost-effective if other parts are worn.
6. Install the New Strut Mount
Position the new strut mount onto the strut assembly. Reinstall and torque the nut to the manufacturer-recommended specifications. Gradually decompress the spring, ensuring it rests securely in the mount and strut assembly.
7. Reattach the Strut Assembly
Align the strut assembly and bolt it back to the knuckle and chassis. Torque all bolts to the correct specifications listed in your repair manual.
8. Test and Realign
Reinstall the wheel and lower the vehicle.
Test drive the car to ensure the suspension feels stable and there are no abnormal noises. Consider getting a professional wheel alignment after replacing the strut mounts to ensure proper handling and even tire wear. By carefully following these steps, you can replace your strut mounts with confidence and restore your suspension system's performance.
FAQs About Strut Mount Replacement
Replacing a strut mount can raise several questions, especially for DIY mechanics. Here are some commonly asked questions:
How long does it take to replace a strut mount?
Replacing a single strut mount typically takes about 1.5 to 3 hours, depending on your experience level and whether you encounter difficulties like stuck bolts.
Can I drive with a bad strut mount?
While it’s technically possible, driving with a faulty strut mount is dangerous. It can compromise your vehicle’s handling, cause excessive tire wear, and lead to further suspension damage. Replace it as soon as possible.
How much does it cost to replace a strut mount?
Costs vary depending on the make and model of your vehicle, but the typical price for parts ranges from $40 to $150 per strut mount. Labor costs at a professional shop can add $100 to $300 per mount.
Do I need a spring compressor to replace a strut mount?
Yes, a spring compressor is essential for safely removing and reinstalling the strut mount. Without it, the compressed spring could release suddenly, causing serious injury.
Should I replace all strut mounts at the same time?
It’s generally recommended to replace both strut mounts (front or rear) at once. If one has failed, the other is likely to be close to failing as well.
