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