Posi Going Out?

I am on ET Streets, I was hoping this was a problem caused by the lack of a Line Lock, well I have a SJM one that is going in soon. I thought that there was just too much force for the posi to overcome on the left tire so it only spun the right one, is it possible, or is my posi dead. :dunno:
the leak i used the bottle on street tires once
this is a shot of the same rear end just added a solid pinion spacer and some 4.10's
this is going to be certain death for the little 7.625 10 bolt welcome to the F body's down fall
