well, no, I did not need a spring compressor, as long as the control arm was supported. But I needed impact tools to loosen the bolts. Unfortunately, the rear lower bolt is positioned in such a way, that only a flat wrench or an impact tool will get it off. so, because of that (I took off all other bolts, and broke two flat wrenches), I could not finish. I ahve to go to a shp so they'll loosen up these ^%$#%$*& bolts. otherwise it looks very easy. by the way, the spring compressor I had did not fit the spring. go figure
