Check out the How-To sicky on the top of the page. The Green GT put up a pretty good walkthrough which helped me when I did my springs and shocks/struts.
If you get stuck and cant get the springs out for some reason, you can drop the LCA at the K-member and do it that way. I have pointers on that method if needed. It shouldnt be needed on an SN (it is really effective on foxes).
