If you are talking about the triangle shaped bushings then the only way I have found to replace them is to cut open the bracket, place it around the bushing (after it is on the swaybar) and then carefully weld the bracket back together. Tried making a setup to press the bushings in and never had success; gave up and ground out a weld and opened the bracket up. Managed to not damage the bushing when we welded the bracket back together but it was close!
