I'm not very knowlegeable (sp) when it come to rear ends, but I notice today when I swapped my wheels that I was able to turn the drivers side wheel with it in gear and the e-brake on. This kinda worried me that an axle may be broke or something else. Any help???

 

I believe that would be the charecteristics of a torsen posi unit. An Auburn which came in earlier 4th gens wouldnt allow it. Also, I doubt your axle coumd be broken because stock 10 bolt axles in 4th gen camaros (or 3rd gen 10 bolts for that matter) have "C" clip axles which, if broken, would just slid right out of the houseing (scary huh?) thats why they make "C" clip eliminators, I would imagine guys who road race probably use them a lot.

although i dont know how it would spin with your e-brake on unless it needs to be adjusted...

 

Maybe but I tried the passenger side and I didnt do it I'll try that out.

 

Your e-brake need to be ajusted, and do both sides not just the one.
And there is nothing wrong with your axil, its just the posi slipping.
