you will need to rent or buy a spring compressor and a lca bushing removal tool. i replaced them without the bushing removal tool, and they were a pita to get out, took me over 6 hours to replace both sides. in order to get the control arm out you will need to remove the spring. the right way to remove the springs is with the klann spring compressor, but i removed them by lowering the control arm with the help of carjack and jackstands. this is a very dangerous way of doing it because the spring can hurt you or even kill you if it flies off, so don't attempt this way if have never done it before.
once i got the control arm out, i used a blue torch to get the old bushing out. also i had previously put the new bushings in dry ice for a few hours so they would go in easier. while doing this job i also recomend changing the lower ball joints, swaybar/stabilizer links and bushings if those have never been changed. by the way i bought lemforder brand lca bushings from bmaparts, i think for lca bushings, stabilizer links and stabilizer bushings all together were around $150. the front end was definitely more solid after the change. also i had to play with the tie rods a little bit until i got the steering straight because car would lean to the left after the lca bushings change.
if i had to redo the whole process again i would just have an indie do it. i was quoted around $550-600 by an indie for oem parts + labor.
