removing lwr control arm pivot

I've used my floor jack plenty of times to get them out. Take the jack pad out, and stick the pin up thru the hole from the bottom. Put the lower control arm pointing towards the back of the jack, so the jack will hold it down. Put a big washer or 3 on it and put the nut back on. Stand on the jack and pump it up! It will pull the pin out fairly easy if the bushings are old and tired. I've taken a hacksaw apart and stuck the blade thru the rubber bushing after knocking the sleeve out, and sawed thru the rubber. Then you can remove the hacksaw, and curl the rubber up into itself and pull it out. If you don't need the outer shell to reuse, an air chisel will make short work of that.....but be careful not to muck up the control arm!
