Radius arm bushings are removed by removing the wheel. Unbolt the radius arm from the control arm. Mark the angle of the radius arm. Then unbolt the radius arm cover. Now comes the hard part. Pull the radius arm off of the torsion bar.

Once the radius arm is removed you have to then cut the rubber bushing off of the radius arm.

What some people do to save money is switch the left and right radius arms because the top of the bushing is what carries the load and is the side that wears out. Personally I consider my time to valuable to take such a shortcut.

To remove the control arm bushing you need start like you did with the control arm. Remove wheel, unbolt control arm from radius arm. Disconnect brake lines. (You should change them and rebuild the calipers while your at it. Change the fluid as well. All easy and inexpensive to do.) Now you can unbolt the the control arm from the torsion bar tube. Remove control arm and extract the bushing. When you reassemble. Install the bolts from outside in so that the nut is next to the tranny. This way if you need to get back in there you won't have to remove the motor and tranny.

That's the short story version. Check the Pelican Tech articles for a more in depth version.
