You'll have to use a gear puller to get the old bushing/bracket assembly off of the control arm. Then you'll have to have the old bushings pressed out of the bracket (also commonly called the "lollipop") and the new ones pressed back in. I took mine to a little automotive shop down the road that did the press work for me for a few bucks. After you get the new bushings pressed into the brackets, lube up the bushing and control arm end with some dish soap, push the bushings back on the control arms, bolt the lollipops back up to the frame quickly, and let the car down off of the jackstands quickly. Push the front of the car up and down several times to work the bushings into their resting loaded positions on the control arms, and let the car sit for several hours before taking it for a drive to let the dish soap dry out. It's pretty easy.
