Excuse me everyone, I'm trying to buy a diff from a 95 Z28, but I have a doubt, it wasn't possible to lift the car to check if the wheels spin to the same side, but it was possible to pick up only one, but it spin, so my doubt if is a "posi" diff it is possible that its happens, cause til I now, the wheels has to be stuck, or I don´t know how to say, or is possible that a Z28 doesn´t have a posi differential, thanks for your help, to every one.

 

The '95 would have the Auburn differential. It is very possible that it is worn out. If it is worn out then it is useless. The only way to be sure of what is in it is to remove the cover and look inside.

 

thank you big gear head, I´m gonna try to remove the cap, thanks for all.
