Jack the car up until the stock spring is compressed and install the coil spring compressor by sliding the hooked section of the tool onto the top and bottom part of the spring, effectively holding the compressed spring in place. Remove the lug nuts and pull the wheel off of the wheel studs. Use the socket set to remove the nut from the top of the strut tower, which is the cylindrical rod extending up through the coil spring itself.
