The cost will depend on the make and model of your vehicle, the type of coil spring, and whether you do it yourself or hire a mechanic.

Replacing a coil spring might seem like a daunting task, but with the right tools, knowledge, and a bit of elbow grease, it’s a job that many DIYers can tackle themselves. This comprehensive guide will walk you through every step of the process, from gathering the necessary tools to safely installing the new springs.

Safety First

Before you begin, safety should be your top priority. Here are some essential precautions:

Park your vehicle on a level surface and engage the parking brake.
Use jack stands to support the vehicle securely.
Wear safety glasses and gloves at all times.
Be aware of the potential for falling parts and sharp edges.

Step-by-Step Instructions

1. Gather Tools and Materials

You’ll need the following tools and materials:

New coil springs
Jack stands
Floor jack
Socket wrench set
Torque wrench
Spring compressor
Safety glasses
Gloves

2. Remove the Wheel

Use the socket wrench to loosen the lug nuts on the wheel associated with the coil spring you’re replacing. Jack up the vehicle and place a jack stand under the appropriate jack point. Remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper

Locate the brake caliper and remove the bolts holding it in place. Carefully lift the caliper off the rotor and hang it from the suspension using a bungee cord or wire. Do not let it hang by the brake hose.

4. Remove the Strut Assembly

Use the socket wrench to remove the bolts connecting the strut assembly to the steering knuckle. Carefully pull the strut assembly away from the knuckle and lower it to the ground.

5. Compress the Coil Spring

Position the spring compressor over the coil spring and slowly tighten the bolts to compress the spring. Compress the spring until it’s safe to remove the strut mount.

6. Remove the Strut Mount

Remove the bolts holding the strut mount to the strut assembly. Carefully lift the strut mount off the assembly and set it aside.

7. Install the New Coil Spring

Carefully slide the new coil spring onto the strut assembly. Ensure that the spring is properly seated and facing the correct direction.

8. Reassemble the Strut Assembly

Place the strut mount back onto the strut assembly and tighten the bolts. Slowly release the spring compressor by loosening the bolts.

9. Reinstall the Strut Assembly

Lift the strut assembly back into place and align it with the steering knuckle. Tighten the bolts connecting the assembly to the knuckle.

10. Reinstall the Brake Caliper

Place the brake caliper back onto the rotor and tighten the bolts holding it in place.

11. Reinstall the Wheel

Put the wheel back on and tighten the lug nuts. Lower the vehicle and torque the lug nuts to the specified torque.

Tips for Success

Use a torque wrench to tighten all bolts to the specified torque.
Inspect the other coil spring for any signs of wear or damage.
If you’re replacing both coil springs, do one side at a time to ensure the vehicle remains stable.
If you encounter any difficulties, don’t hesitate to consult a mechanic.

Signs of a Bad Coil Spring

Sagging or uneven ride height
Abnormal noises when driving over bumps
Reduced handling and stability
Increased tire wear

Wrapping Up

Replacing a coil spring can be a challenging but rewarding task for DIY enthusiasts. By following the steps outlined in this guide, you can safely and effectively restore your vehicle’s suspension to optimal performance. Remember to prioritize safety and consult a mechanic if you encounter any difficulties.
