buy or rent a spring compressor from autozone.  you would also need a
special socket setup to remove the shock cartridge from the shock
housing.  Basically you would need two set of special tool before you
start.  Also one more note:  the 2 lower bolts on the shock be sure and
indentify the head of the bolt and put a wrench on it and be sure it
does not turn when you turn the nut off because the bolt is grooved.
Penetrating oil or wd-40 would help.  spraying it the night before
works even better.  Good luck!  I am not an expert but I changed two
sets of front shocks on my caravans and its fairly straight forward,
except for the above mentioned items.

1. 2-bolts at the bottom
2. 3-bolts under the hood
3. remove brakeline clamped onto the shock tower
4. I am not sure if you need to remove the suspension link near the
shock
5. the shock should drop

I hope I helped you!
