Start by removing the front calipers and wiring them up out of the way, be careful not to damage the hoses. Now you can begin to remove the control arms, you have to remove the sway-bar end-link from the arm, followed by the tension rod bolts on the bottom of the arm, followed by the bolts on the bottom of the strut that attach the strut to the steering knuckle, and last but not least, the bolts holding the arms to the cross-member. (ok, that was one HUGE run-on sentence).
your car should now look like this:
(notice I removed my struts, this was to install the 88SS springs, you do not need to do this in order to swap the control arms)
The old bushings should be burned out in the same manner as the rear bushings, but this time you will not need to save the inner sleeve since they are provided with the bushings. Also, be careful not to heat the control arm itself too much, you can actually weaken it (bad thing). Now clean the inside of the outer bushing sleeve with a scotch brite pad, then grease and insert the new bushings. Make sure to use plenty of grease, and only the grease that came with the bushings! The arms should be ready to go back in the car at this point.
This is the "early" style arm on the top with a stock rubber bushing and a "late" style arm on the bottom with a poly bushing:
Now simply put everything back together the way you took it apart. This is a picture of the arm in the car.
Now go get a front end alignment (or DO IT YOURSELF), you most likely will need it. Enjoy!
