I picked up an Internal Coil Spring Compressor to use on the Ranch Wagon. After fiddling with it for awhile, I got the hang of using it and its function. It has 4 arms with hooks that are inserted through the middle of the coils spring, rather than the ones that mount on the outside of the spring. My opinion is that the internal Coil Spring compressor is a safer tool, and works better.
Working with coil springs is always dangerous. They are under enormous tension, so be careful and always take safety measures to ensure that you will not get hurt.
Now that the Spring is removed, carefully set the spring aside. It is still under tension with the spring compressor attached to it! I carefully loosed the tension by loosening the nut on the compressor until it loosed up. I ran out of daylight, so I will have to do the other side tomorrow evening.
