front spring shackle replacement? tips tricks or warnings?

[mike657894]

I am about to replace the worn bushings with a new shackle kit from snyders. Is it a straight forward process? support the car lower the alxe and remove the shackles? Or is some or a lot of spreading required and how should I go about this? I see threads on the rear and spreaders. I did some searching but found nothing about stock front spring service. If its simple and I can just go for it with basic tools let me know. I have a 12ton press if the bushings have to be pressed.
