Springs installation (need help)

ok i've completely installed 2 of my springs in front. now i am having trouble taking out the bottom screw in the rear. i think the screw's weldered or something because when i try to unscrew its, it wont even notch. i broke one of my socket already and i took my car to pepboy and they charge me 340 dollars for installing the 2 rear springs with an aligment. i dont wanna pay that much. so could u guy, who've installed springs on ur own, tell me how u take the 2 nuts in the rear wheel out?
thanx

you mean the ones to the lower control arm? and what do you mean by "notch"?

yeah the one in the lower arm. what i meant was it didnt even move.

well the screw isn't welded so you just have to use some gusto. try and use a breaker bar. or put a pipe on the end of a well made ratchet. but a breaker bar would be better. you could also soak it in wd40 for a couple of hours or overnight.
