just finished up the uppers today, even simpler than the first one... after using the ball joint installer tool to install 1 bushing and inserting the cross bar I simply started the bushing in the hole, placed the arm in the vice where the bushing im about to press in flat on the open jaws of the vice. so when i hammer down on the bushing, the metal will not deflect becuase the vice is right there on the arm. I grabbed a 42mm socker or so and placed it over the bushing were its only on the metal sleeve and gave it a few wacks with a brass 2 lb hammer... went right in.
The lowers were a pain in the butt to remove. after getting the cross shaft out.. which took a while since the bushings werent totally shot, i used the air hammer chissel to remove the rest of the rubber on the inside of the shell. I used the chissel bit to fold in the shell so it looks like an inverted flower kinda... well once it was past the inner portion of the arm, i just kept on air hammering till the shell came out... probablly took 5 minutes.. Used the same method to install the bushing as before with the vice and a socket. Work had some suspension and wheel bearing cups, and one was perfect.. so it was more round than a socket but same concept. hammered it right in with no sweat.
once I install the arms on the truck and set it at ride height i will torque down the cross shaft bolts.
not to hard if you have some sort of cups or maybe even a piece of pipe thats the right diameter..
