How do i remove the 4 bolts on the back of the wheel bearing on a 2005 g35x. i cannot get back there. for all of them. is it a must to disconnect the suspensoin? Or do i have to remove the drive shaft? I'm hoping that i dont have to remove too much, but even if i can squeeze in there and remove them, will i need to take the suspension apart to have room to put the bolts back in?

You will need to remove the drive shaft. However, the manual has you disconnecting all of the other suspension arms. Per other posts, you don't need to disconnect the rest of the suspension. The trick is to remove the drive shaft without bending it too much and not messing up the splines. Google 'g35 rear wheel bearing removal' and you should find a g35driver thread.
