[The Gibster]

Right now i am in the middle of making my blazer finally drivable. Last time I was home, I lifted the back of it up to check and see if it had a locker or anything (I bought it with the 14 bolt already in) and when i spun the driver side wheel the passenger side didn't move at all but the yoke did. From reading up on other posts both the g-80 and an open diff should rotate in opposite directions. Is the carrier blown? thanks!
