4. In order to install the new lower ball joint, the sway-bar connector arm tab needs to be removed (arrow). This tab is welded onto the stock lower control arm and can be easily removed using a Sawzall with a metal-cutting blade. We removed the tab, cutting it flush with the top of the lower control arm. Once removed, a grinder was used to smooth the area. We wiped down the area with a cleaning solvent and spray-painted the surface black.
