'81 Z28? If it is then you have the 8.5 corporate rear end. That will have the Traction Lock differential. It's very comon for the clutches to wear and loose their preload, which will make it act like a standard differential when you try turning the wheels like that. The only way that you are going to know what you have is to remove the cover and look inside. There is no other way to be sure. There are after market reproduction clutches available for these now at about $200 a set with shims. They are no longer available from GM. You can also shim the clutches that are in it if they are not worn too much.
