This is pretty straight forward. Raise the car and put the front end on jack stands. Remove the trires and wheel. Remove the shock absorber and use a spring compressor to compress the spring. I use an electric impact gun to work this tool. once the spring is compressed, remove the nut from the top of the lower ball joint, and then use a pickle fork to separate the ball joint from the spindle. Once the ball joint is separated, push the lower A frame down and remove the spring. Replace the top spring insulator. Compress the new spring and put in place making sure that the bottom spring end fits in the detent in the lower A frame. put the ball joint back together and then uncompress the spring and remove the compressor. Reinstall the shock, tire and wheel and you are done with one side.
