Expert Tips: How to Remove Coil Spring from Strut in Minutes

Replacing struts and shocks is a common car maintenance task that often involves removing the coil spring. While it might seem daunting, the process is manageable with the right tools and a clear understanding of the steps. This blog post will guide you through the process of safely and effectively removing a coil spring from a strut, providing you with the knowledge to tackle this task with confidence.

Gather Your Tools and Equipment

Before you dive into the removal process, ensure you have the necessary tools and equipment. This will make the job smoother and safer. Here’s a checklist:

• Jack and Jack Stands: To safely lift the vehicle and secure it while working.
• Lug Wrench: To loosen the lug nuts on the wheel.
• Wheel Chocks: To prevent the vehicle from rolling while it’s lifted.
• Torque Wrench: To tighten bolts and nuts to the correct specifications.
• Socket Set: To remove and install nuts and bolts.
• Spring Compressor: This is a crucial tool for safely compressing the coil spring.
• Penetrating Fluid (Optional): Helps loosen rusted bolts.
• Safety Glasses: To protect your eyes from flying debris.
• Gloves: To protect your hands.

Preparing Your Vehicle

1. Park on a Level Surface: Ensure your vehicle is parked on a solid, level surface. This will help maintain stability and prevent accidents during the process.
2. Engage the Parking Brake: Engage the parking brake to prevent the vehicle from rolling.
3. Chock the Wheels: Place wheel chocks behind the rear wheels to prevent the vehicle from rolling during the lift.
4. Loosen Lug Nuts: Using the lug wrench, loosen the lug nuts on the wheel that corresponds to the strut you’re working on. Don’t remove them completely yet.

Lifting the Vehicle

1. Position the Jack: Locate the jacking point near the strut you’re working on. Refer to your vehicle’s owner’s manual for the precise location.
2. Raise the Vehicle: Slowly raise the vehicle using the jack until the wheel is slightly off the ground.
3. Secure with Jack Stands: Place the jack stands securely under the vehicle’s frame, ensuring they are properly positioned to support the weight safely.
4. Remove the Wheel: Once the vehicle is securely supported, remove the wheel by fully unscrewing the lug nuts.

Disconnecting the Strut

1. Identify the Strut Components: Locate the strut assembly, which includes the strut itself, the coil spring, and the strut mount.
2. Disconnect Stabilizer Bar Link: If applicable, disconnect the stabilizer bar link from the strut. This may require loosening a nut or bolt.
3. Disconnect Brake Line: Carefully disconnect the brake line from the strut. This is typically done by loosening a clamp or clip.
4. Remove Strut Mount Bolts: Identify the bolts attaching the strut to the vehicle’s body. Use the appropriate socket to loosen and remove these bolts.

Compressing the Coil Spring

1. Secure the Spring Compressor: Carefully position the spring compressor around the coil spring, ensuring the arms are properly engaged.
2. Compress the Spring: Slowly compress the spring using the spring compressor handle. Be cautious and avoid over-compressing the spring, as this can cause damage.

Removing the Coil Spring

1. Remove the Strut Mount: Once the spring is compressed, remove the strut mount from the top of the strut. This may require loosening or removing a nut or bolt.
2. Release the Compression: Carefully release the spring compressor while keeping the spring compressed.
3. Remove the Coil Spring: With the spring compressed, remove it from the strut assembly.

Reversing the Process

1. Install the New Coil Spring: If you’re replacing the coil spring, install the new spring onto the strut.
2. Re-compress the Spring: Use the spring compressor to compress the new spring to its original height.
3. Reinstall the Strut Mount: Reinstall the strut mount on top of the strut.
4. Tighten the Strut Mount Bolts: Tighten the strut mount bolts to the specified torque.
5. Release the Spring Compressor: Carefully release the spring compressor.
6. Reconnect the Brake Line: Reattach the brake line to the strut.
7. Reconnect the Stabilizer Bar Link: If applicable, reconnect the stabilizer bar link to the strut.
8. Lower the Vehicle: Lower the vehicle using the jack.
9. Tighten Lug Nuts: Tighten the lug nuts on the wheel to the specified torque.

Final Touches: Ensuring a Smooth Ride

1. Test Drive: After completing the installation, take your vehicle for a test drive to ensure the new strut and spring are functioning properly.
2. Inspect for Leaks: Check for any leaks from the strut or brake lines.
3. Adjust Alignment (If Necessary): If you suspect the alignment might have been affected during the installation, consider getting a wheel alignment done by a professional.

Riding into the Sunset: A Final Word

Replacing a coil spring is a rewarding DIY task that can save you money. By following these steps, you can confidently remove a coil spring from a strut and ensure your vehicle’s suspension is in top shape. Remember to always prioritize safety and use the appropriate tools.

Answers to Your Most Common Questions

Q: What are the signs that a coil spring needs to be replaced?

A: You might need a new coil spring if you notice a noticeable drop in ride height, uneven tire wear, squeaking or clunking sounds when driving over bumps, or a bouncy ride.

Q: Can I reuse the old coil spring?

A: It’s generally not recommended to reuse an old coil spring, especially if it shows signs of wear or damage. This can compromise the safety and performance of your vehicle’s suspension.

Q: How often should I replace the coil springs?

A: The lifespan of coil springs varies depending on driving conditions and vehicle usage. However, it’s generally recommended to inspect them every 50,000 to 75,000 miles.

Q: Is it dangerous to work on car suspension without proper training?

A: Working on car suspension can be dangerous if you don’t have the proper knowledge and experience. It’s always best to consult a qualified mechanic if you’re unsure about any aspect of the process.
