If a Press is not available or the bushing cannot be pressed, using a vice (if you do not have a vice, secure the control arm to an object such as table or platform) Clamp the control arm so that the front bushing points towards the ground, the rear bushing will be In the air. Using a torch, Heat the outer housing of the control arm that holds the bushing. The metal will get hot, possibly glow, once the bushing begins to catch fire and/or smokes, stop heating and blow out flames.
