Do thoses bushing drivers you see around actually work for getting out bushings? I need to change out rear bushings( torque rod, panhard). Trailing arm bushings were done a couple of years ago and look fine. The others are toast. There is barely anything left in them. They move all over the place. Can you get them out w/o a press. Do you just hammer on thoses drivers with those round plates to push them out? Worth trying or get them done? Thanks
