I do not have the special tool or a ball joint folk, so it is not easy to get it off. I unscrewed all screws, there are only two screws, one is on the rotor side (18mm), the other one is on sub-frame side (22mm). I just tried to tap it off or just use hand force to get it off. That is wahy I failed. Someone here said that it was very easy to get it off by using a hammer, but not for me. Can anyone tell me that how to use the puller or the ball joint folk to get the control arm off? Thanks a lot!
