Re: my rear axle shaft (?) is busted. help!
Could be simple, could be no. Get that corner up in the air and get underneath. Is the disconnect where the "driveshaft" (as Nissan calls them, we call them "halfshafts" generally) bolts up to the stub axle flange that comes out of the back of the wheel hub? Or is that flange still bolted up correctly and but has broken away from the axle? Wait, you've got the outer universal joint circled in the diagram, is it split right there?
I hope it is the first case, and the halfshaft bolts just became loose and you somehow sheared them off. Can you get a clear digital picture of it and post it?
