I have 2007 g35 coupe. I got my front suspension in. Im using ISC N1 Coilovers. In this video if you look at 8:25 to 8:45. The screw and nut that they took out so easily, mines is seize with the bushing on both sides. Is there any way of removing the screw and bushing and replace them without taking out the whole spindle. I have a mechanic saying that they need to remove the whole rear axle knuckle to replace that one bushing and screw. You know the price for something like that is outrageous. Is there any tool I can use to install a new bushing on that shock without removing the whole thing?
