Installing replacement coil springs on your car requires the right technique and some specialist equipment. The job is not extremely difficult, but it is risky. If you observe some sensible safety precautions, you stand a better chance of success. To remove the coil from the strut you must, above all, observe safety. The coil springs must be compressed before you undo the bolt at the top of the strut. This is one of the most dangerous parts of vehicle maintenance and the spring can uncoil and do serious harm. Use the compression brackets at 180 degrees, opposite each other on the spring and tighten them evenly with about 8 – 10 turns each before swapping. Once they have been compressed tightly, you can remove the holding bolt at the top of the strut and take the coil off.
