Coil springs are an essential component of a vehicle’s suspension system, absorbing shocks and vibrations to ensure a smooth ride. However, when replacing or repairing a strut, removing the coil spring can be a daunting task. This comprehensive guide will provide a detailed step-by-step approach to safely and effectively remove a coil spring from a strut.
Safety Precautions
Before proceeding, it is crucial to prioritize safety:
- Wear appropriate safety gear, including gloves, safety glasses, and earplugs.
- Ensure the vehicle is parked on a level surface and the parking brake is engaged.
- Use a sturdy jack and jack stands to support the vehicle securely.
- Allow the suspension to fully settle before attempting any work.
Tools and Materials
To remove a coil spring from a strut, you will need the following tools and materials:
- Spring compressor
- Impact wrench or socket wrench
- 18mm socket or wrench
- 19mm socket or wrench
- Torx bit (size varies depending on vehicle)
- Penetrating oil (optional)
Step-by-Step Guide
1. Prepare the Spring Compressor
Begin by assembling the spring compressor according to the manufacturer’s instructions. Ensure that the compressor is compatible with the size and type of spring you are removing.
2. Position the Compressor
Place the spring compressor over the coil spring, aligning it with the grooves on the spring. Tighten the compressor gradually until it is securely in place.
3. Remove the Upper Nut
Using an impact wrench or socket wrench with an 18mm socket, remove the upper nut that connects the strut to the vehicle’s frame.
4. Detach the Sway Bar Link
Locate the sway bar link that connects the strut to the sway bar. Using an 18mm socket or wrench, loosen and remove the nut that secures the link to the strut.
5. Remove the Lower Bolts
Use a 19mm socket or wrench to remove the two lower bolts that connect the strut to the steering knuckle.
6. Separate the Strut from the Knuckle
Carefully pull the strut away from the steering knuckle. The coil spring will remain compressed by the spring compressor.
7. Release the Spring Compressor
Slowly and carefully release the spring compressor, allowing the coil spring to expand.
Additional Tips
- If the upper nut is seized, apply penetrating oil and allow it to soak before attempting to remove it.
- Use a wire brush to clean any rust or debris from the bolts before attempting to remove them.
- Be cautious when releasing the spring compressor, as the spring can expand with force.
- If you are not comfortable performing this task, consult with a qualified mechanic.
Wrapping Up: A Job Well Done
Removing a coil spring from a strut requires careful preparation, safety precautions, and the right tools. By following the steps outlined in this guide, you can safely and effectively complete this task, ensuring a smooth and comfortable ride for your vehicle.
Questions We Hear a Lot
