lower control arms can be done with just ramps and a floor jack and hand tools. (i did it). you remove the 3 bolts from the bottom end of the strut. then you undo the tie rod connecting to it and i think the lower swaybar link ball joint.

once the plate connecting the control arms is taken off - you undo the bolt on the lower control arm and hammer it out placing it on some bricks or sockets (Bill R method).

I would say 2 hours per side, working at home, or 1.5 hours at a shop.
