lol i dont think its very likely the spring will actually fly out of the front, i had to push down rly hard on the a-arm to get it down far enough to get the stock spring out. as for the back, its really easy basically all u have to do is take the sway bar off, then take out 1 bolt that holds the lower control arm to the axle(with the floorjack underneath it ofcourse) then let the jack down slowly, pull the spring out, put the new one in, jack it back up, put the bolt back in, repeat on the otherside, put the swaybar back on, done lol. you dont even need a spring compressor because the control arms go down far enough you can just put the spring in then jack it up with a floor jack.
