put a C-clamp on the spring, (up near center bolt) take the center bolt out, loosen C-clamp slowly until the spring is relaxed. take each spring off. you wont need a spring spreader as the main leaf comes off easily once all the leaves are off. just unbolt shackles.
install on the new axle the same way. bolt main leaf onto axle/shackles, once its on stack the other leaves on and run the bolt back through. clean each spring up, paint them, maybe add Teflon strips in between each spring before installing.
oil spring perches, don't pound them. stick a rod/ long screwdriver in shackle hole, twist back and fourth until loose.
