i would very much so disagree with this as I found the backs easy as hell! But then again each LS is in its own condition and different things are worn in different places. I had a hell of time with my right front, but the left front was easy and the rears took less time combined than the left front took alone.
loosen the two (I beleive 18mm) bolts on the control arm. Thats what holds the control arm up, or makes it springy.
just remember to lift it back up when you tighten it, or it will squeak like mine did.
