Being that it is your first time doing it, it would be about a 4 - 5 hour job.

Front struts:

1)Jack up driver side of car
2)Remove wheel to show strut fork and strut assembly
3)Remove swaybar link bolt (on the fork, to to the left of where the strut enters the fork & You must use pliars to hold the nut on the back of it.)
4)Remove bolt on the back of the strut fork (It come from the left)
5)Remove long bolt at the bottom of the fork.
6)Pop hood
7)Remove the 3 strut tower nuts
8)Get a friend
9)Pull the bottom of the strut out of the fork. Have one person push the strut assembly up as the other uses a hammer and pushes/wacks the fork down. (This is a bitch and takes some time)
10)With the strut assembly out, use a spring compressor and compress the stock spring so it doesn't shoot off in the next steps
(If you want a spring compressor I'll sell you mine for $20)
11)Remove the nut from the top of the assembly
12)Take each piece out one by one maintaining order, and swap in the new strut.
13)Put the assembly back together
14)Now insert the assembly and follow instruction in reverse order
15)Repeat for Passenger side

Rear Struts:

1)Jack up driver side of car
2)Remove wheel
3)Remove lower strut bolt, going through the bottom of the strut.
4)Remove strut tower bolts (Be careful the strut will fall out, have a friend hold it as you remove strut tower bolts)
5)Remove the nut from the top of the assembly
6)Take each piece out one by one maintaining order, and swap in the new strut.
7)Put the assembly back together
8)Now insert the assembly and follow instruction in reverse order
9)Repeat for Passenger side

Its sort of a pain, and you'll get very dirty, but afterwards you will know exactly how your suspension is, and how it all works...which is nice to know. Also you'll save money..
